Battle of Kursk
The Battle of Kursk was a Second World War engagement between German and Soviet forces on the Eastern Front near Kursk in the Soviet Union, during July and August 1943. The battle began with the launch of the German offensive, Operation Citadel, on 5 July, which had the objective of pinching off the Kursk salient with attacks on the base of the salient from north and south simultaneously. After the German offensive stalled on the northern side of the salient, on 12 July the Soviets commenced their Kursk Strategic Offensive Operation with the launch of Operation Kutuzov against the rear of the German forces in the northern side. On the southern side, the Soviets launched powerful counterattacks the same day, one of which led to a large armoured clash, the Battle of Prokhorovka. On 3 August, the Soviets began the second phase of the Kursk Strategic Offensive Operation with the launch of Operation Polkovodets Rumyantsev against the German forces in the southern side of the Kursk salient; the battle was the final strategic offensive that the Germans were able to launch on the Eastern Front.
Because the Allied invasion of Sicily had begun, Adolf Hitler was forced to have troops training in France diverted to meet the Allied threat in the Mediterranean, rather than use them as a strategic reserve for the Eastern Front. Hitler canceled the offensive at Kursk in part to divert forces to Italy. Germany's extensive losses of men and tanks ensured that the victorious Soviet Red Army enjoyed the strategic initiative for the remainder of the war; the Germans hoped to weaken the Soviet offensive potential for the summer of 1943 by cutting off the forces that they anticipated would be in the Kursk salient. The Kursk salient or bulge was 250 kilometres long from north to south and 160 kilometres from east to west; the plan envisioned an envelopment by a pair of pincers breaking through the northern and southern flanks of the salient. Hitler believed that a victory here would reassert German strength and improve his prestige with his allies, who were considering withdrawing from the war, it was hoped that large numbers of Soviet prisoners would be captured to be used as slave labour in the German armaments industry.
The Soviet government had foreknowledge of the German intentions, provided in part by the British intelligence service and Tunny intercepts. Aware months in advance that the attack would fall on the neck of the Kursk salient, the Soviets built a defence in depth designed to wear down the German armoured spearhead; the Germans delayed the offensive while they tried to build up their forces and waited for new weapons the new Panther tank but larger numbers of the Tiger heavy tank. This gave the Red Army time to construct a series of deep defensive belts; the defensive preparations included minefields, artillery fire zones and anti-tank strong points, which extended 300 km in depth. Soviet mobile formations were moved out of the salient and a large reserve force was formed for strategic counter-offensives; the Battle of Kursk was the first time in the Second World War that a German strategic offensive was halted before it could break through enemy defences and penetrate to its strategic depths.
The maximum depth of the German advance was 8–12 kilometres in the north and 35 kilometres in the south. Though the Red Army had succeeded in winter offensives their counter-offensives following the German attack at Kursk were their first successful strategic summer offensives of the war; as the Battle of Stalingrad ground to its conclusion, the Red Army moved to a general offensive in the south, in Operation Little Saturn. By January 1943, a 160 to 300 km wide gap had opened between Army Group B and Army Group Don, the advancing Soviet armies threatened to cut off all German forces south of the Don River, including Army Group A operating in the Caucasus. Army Group Center came under significant pressure as well. Kursk fell to the Soviets on 8 February 1943, Rostov fell on 14 February; the Soviet Bryansk and newly created Central Fronts prepared for an offensive which envisioned the encirclement of Army Group Center between Bryansk and Smolensk. By February 1943 the southern sector of the German front was in strategic crisis.
Since December 1942 Field Marshal Erich von Manstein had been requesting "unrestricted operational freedom" to allow him to use his forces in a fluid manner. On 6 February 1943, Manstein met with Hitler at the headquarters in Rastenburg to discuss the proposals he had sent, he received an approval from Hitler for a counteroffensive against the Soviet forces advancing in the Donbass region. On 12 February 1943, the remaining German forces were reorganised. To the south, Army Group Don was placed under Manstein's command. Directly to the north, Army Group B was dissolved, with its forces and areas of responsibility divided between Army Group South and Army Group Center. Manstein inherited responsibility for the massive breach in the German lines. On 18 February, Hitler arrived at Army Group South headquarters at Zaporizhia just hours before the Soviets liberated Kharkov, had to be hastily evacuated on the 19th. Once given freedom of action, Manstein intended to utilise his forces to make a series of counterstrokes into the flanks of the Soviet armoured formations, with the goal of destroying them while retaking Kharkov and Kursk.
The II SS Panzer Corps had arrived from France in January 1943, refitted and up to near full strength. Armoured units from the 1st Panzer Army of Army Group A had pulled out of the Caucasus and further strengthen
The Continuation War was a conflict fought by Finland and Nazi Germany, as co-belligerents, against the Soviet Union from 1941 to 1944, during World War II. In Russian historiography, the war is called the Soviet–Finnish Front of the Great Patriotic War. Germany regarded its operations in the region as part of its overall war efforts on the Eastern Front and provided Finland with critical material support and military assistance; the Continuation War began 15 months after the end of the Winter War fought between Finland and the USSR. There have been a number of reasons proposed for the Finnish decision to invade, with regaining territory lost during the Winter War being regarded as the most common. Other justifications for the conflict included President Ryti's vision of a Greater Finland and Commander-in-Chief Mannerheim's desire to liberate Karelia. Plans for the attack were developed jointly between the Wehrmacht and a small faction of Finnish political and military leaders with the rest of the government remaining ignorant.
Despite the co-operation in this conflict, Finland never formally signed the Tripartite Pact that had established the Axis powers and justified its alliance with Germany as self-defence. In June 1941, with the start of the German invasion of the Soviet Union, the Finnish Defence Forces launched their offensive following Soviet airstrikes. By September 1941, Finland occupied East Karelia and reversed its post–Winter War concessions to the Soviet Union along the Karelian Isthmus and in Ladoga Karelia; the Finnish Army halted its offensive past the old border, around 30–32 km from the centre of Leningrad and participated in besieging the city by cutting its northern supply routes and digging in until 1944. In Lapland, joint German–Finnish forces failed to capture Murmansk or cut the Kirov Railway, a transit route for lend-lease equipment to the USSR; the conflict stabilised with only minor skirmishes until the tide of the war turned against the Germans and the Soviet Union's strategic Vyborg–Petrozavodsk Offensive in June 1944.
The attack drove the Finns from most of the territories they had gained during the war, but the Finnish Army halted the offensive in August 1944. Hostilities between Finland and the USSR ended with a ceasefire, called on 5 September 1944, formalised by the signing of the Moscow Armistice on 19 September 1944. One of the conditions of this agreement was the expulsion, or disarming, of any German troops in Finnish territory, which led to the Lapland War between the former co-belligerents. World War II was concluded formally for Finland and the minor Axis powers with the signing of the Paris Peace Treaties in 1947; the treaties resulted in the restoration of borders per the 1940 Moscow Peace Treaty, the ceding of the municipality of Petsamo and the leasing of Porkkala Peninsula to the USSR. Furthermore, Finland was required to pay $300 million in war reparations to the USSR. 63,200 Finns and 23,200 Germans died or went missing during the war in addition to 158,000 and 60,400 wounded, respectively.
Estimates of dead or missing Soviets range from 250,000 to 305,000 while 575,000 have been estimated to have been wounded or fallen sick. On 23 August 1939, the Soviet Union and Germany signed the Molotov–Ribbentrop Pact, in which the two parties agreed to divide the independent countries of Finland, Latvia, Lithuania and Romania into spheres of interest, with Finland falling within the Soviet sphere. Shortly after, Germany invaded Poland leading to the United Kingdom and France declaring war on Germany; the Soviet Union invaded eastern Poland on 17 September. Moscow turned its attention to the Baltic states, demanding that they allow Soviet military bases to be established and troops stationed on their soil; the Baltic governments signed agreements in September and October. In October 1939, the Soviet Union attempted to negotiate with Finland to cede Finnish territory on the Karelian Isthmus and the islands of the Gulf of Finland, to establish a Soviet military base near the Finnish capital of Helsinki.
The Finnish government refused, the Red Army invaded Finland on 30 November 1939. The USSR was expelled from the League of Nations and was condemned by the international community for the illegal attack. Foreign support for Finland was promised, but little actual help materialised, except from Sweden; the Moscow Peace Treaty concluded the 105-day Winter War on 13 March 1940 and started the Interim Peace. By the terms of the treaty, Finland ceded 11 per cent of its national territory and 13 percent of its economic capacity to the Soviet Union; some 420,000 evacuees were resettled from the ceded territories. Finland retained its sovereignty. Prior to the war, Finnish foreign policy had been based on multilateral guarantees of support from the League of Nations and Nordic countries, but this policy was considered a failure. After the war, Finnish public opinion favored the reconquest of Finnish Karelia; the government declared national defence to be its first priority, military expenditure rose to nearly half of public spending.
Finland purchased and received donations of war materiel during and after the Winter War. Finnish leadership wanted to preserve the spirit of unanimity, felt throughout the country during the Winter War; the divisive White Guard tradition of the Finnish Civil War's 16 May victory-day celebration was therefore discontinued. The Soviet Union had received the Hanko Naval Base, on Finland's southern coast near the capital Helsinki, where it deployed over 30,000 Soviet military personnel. Relations between Finland and the Soviet Union remained strained after the signing of the one-sided peace treaty
Battle of Smolensk (1941)
The First Battle of Smolensk was a battle during the second phase of Operation Barbarossa, the Axis invasion of the Soviet Union, in World War II. It was fought around the city of Smolensk between 10 July and 10 September 1941, about 400 km west of Moscow; the Wehrmacht had advanced 500 km into the USSR in the 18 days after the invasion on 22 June 1941. The German army encountered unexpected resistance during the battle, leading to a two-month delay in their advance on Moscow. Three Soviet armies were encircled and destroyed just to the south of Smolensk, though significant numbers from the 19th and 20th armies managed to escape the pocket; some historians have asserted that the losses of men and materiel incurred by the Wehrmacht during this drawn-out battle and the delay in the drive towards Moscow led to the defeat of the Wehrmacht by the Red Army in the Battle of Moscow of December 1941. On 22 June 1941, the Axis nations invaded the Soviet Union in Operation Barbarossa. At first, the campaign met with spectacular success, as the surprised Soviet troops were not able to offer coordinated resistance.
After three weeks of fighting, the Germans had reached the Dvina and Dnieper rivers and planned for a resumption of the offensive. The main attack aimed at Moscow, was carried out by Army Group Centre, its next target on the way to the Soviet capital was the town of Smolensk. The German plan called for the 2nd Panzer Group to cross the Dnieper, closing on Smolensk from the south, while the 3rd Panzer Group was to encircle the town from the north. After their initial defeats, the Red Army began to recover and took measures to ensure a more determined resistance and new defensive line was established around Smolensk. Stalin placed Field Marshal Semyon Timoshenko in command and transferred five armies out of the strategic reserve to Timoshenko; these armies had to conduct counter-offensives to blunt the German drive. The German high command was not aware of the Soviet build-up until they encountered them on the battlefield. Facing the Germans along the Dnieper and Dvina rivers were stretches of the Stalin Line fortifications.
The defenders were the 13th Army of the Western Front and the 20th Army, 21st Army and the 22nd Army of the Soviet Supreme Command Reserve. The 19th Army, was forming up at Vitebsk. In Soviet histories, the battles around Smolensk are divided into phases and operations to halt the German offensive and the pincers Battle of Smolensk Smolensk Defensive Operation Smolensk Offensive Operation Rogechev-Zhlobin Offensive Operation Gomel-Trubchevsk Defensive Operation Dukhovschina Offensive Operation Yelnia Offensive Operation Roslavl-Novozybkov Offensive Operation Prior to the German attack, the Soviets launched a counter-offensive; the result was a disaster, as the offensive ran directly into the anti-tank defenses of the German 7th Panzer Division and the two Soviet mechanized corps were wiped out. On 10 July, Guderian's 2nd Panzer Group began a surprise attack over the Dnieper, his forces overran the weak 13th Army and by 13 July, Guderian had passed Mogilev, trapping several Soviet divisions.
His spearhead unit, the 29th Motorised Division, was within 18 km of Smolensk. The 3rd Panzer Group had attacked, with the 20th Panzer Division establishing a bridgehead on the eastern bank of the Dvina river, threatening Vitebsk; as both German panzer groups drove east, the 16th, 19th and 20th armies faced the prospect of encirclement around Smolensk. From 11 July, the Soviets tried a series of concerted counter-attacks; the Soviet 19th Army and 20th Army struck at Vitebsk, while the 21st and the remnants of the 3rd Army attacked against the southern flank of 2nd Panzer Group near Bobruisk. Several other Soviet armies attempted to counter-attack in the sectors of the German Army Group North and Army Group South; this effort was part of an attempt to implement the Soviet prewar general defense plan. The Soviet attacks managed to slow the Germans but the results were so marginal that the Germans noticed them as a large coordinated defensive effort and the German offensive continued. Hoth's 3rd Panzer Group drove north and east, parallel to Guderian's forces, taking Polotsk and Vitebsk.
The 7th Panzer Division and 20th Panzer Division reached the area east of Smolensk at Yartsevo on July 15. At the same time, the 29th Motorized Division, supported by the 17th Panzer Division broke into Smolensk, captured the city except for the suburbs and began a week of house-to-house fighting against counter-attacks by the 16th Army. Guderian expected that the offensive would continue towards Moscow as its main focus and sent the 10th Panzer Division to the Desna River to establish a bridgehead on the east bank at Yelnya and cleared that as well by the 20th; this advanced bridgehead became the center of the Yelnya Offensive, one of the first big coordinated Soviet counter-offensives of the war. This objective was 50 km south of the Dnepr and well clear of the objective of liquidating the armies trapped at Smolensk. Under Fuhrer Directive 33 issued on July 14, the main effort of the Wehrmacht was re-orientated away from Moscow
Battle of Brody (1941)
The Battle of Brody was a tank battle fought between the 1st Panzer Group's III Army Corps and XLVIII Army Corps and five mechanized corps of the Soviet 5th Army and 6th Army in the triangle formed by the towns of Dubno and Brody between 23 and 30 June 1941. It is known in Soviet historiography as a part of the "border defensive battles". Although the Red Army formations inflicted heavy losses on the German forces, they were outmanoeuvred and suffered enormous losses in tanks. Poor Soviet logistics, German air supremacy as well as a total breakdown in Red Army command and control ensured victory for the Wehrmacht despite overwhelming Red Army numerical and technological superiority; this was one of the most intense armored engagements in the opening phase of Operation Barbarossa and recent scholarship considers it the largest tank battle of World War II, surpassing the more famous Battle of Prokhorovka. 1st Panzer Group, led by Generaloberst Paul Ludwig Ewald von Kleist, was ordered to secure the Bug River crossings and advance to Rovno and Korosten with the strategic objective of Kiev.
It deployed two corps forward and advanced between Lviv and Rovno in an attempt to cut the Lviv–Kiev railway line, thus driving a wedge along junction point between the Soviet 5th and 6th Armies. The Southwestern Front, under the command of General Mikhail Kirponos, had received incomplete intelligence on the size and direction of the German attack, they were surprised when Stavka ordered a general counter-attack under the title of "Directive No. 3" on the authority of Chief of General Staff Georgy Zhukov. Most of the headquarters staff were convinced that the strategy would be to remain in a defensive posture until the situation clarified. Hovhannes Baghramyan, a staff officer of the front headquarters who wrote the initial report to Moscow, said that "our first combat report to Moscow was full of generalities and unclear instructions." The general orders of Directive No. 3 read: While maintaining strong defense of the state border with Hungary, the 5th and 6th armies are to carry out concentric strikes in the direction of Lublin, utilizing at least five mechanized corps and aviation of the Front, in order to encircle and destroy the enemy group of forces advancing along the Vladimir-Volynski-Krystonopol front, by the end of June 24th to capture the vicinity of Lublin.
By the end of 22 June, Zhukov was on his way to the Southwestern Front headquarters at Ternopil along with Nikita Khrushchev, the former head of the Organizational Department of the Ukrainian Communist Party's Central Committee, to ensure these orders were carried out. Six Soviet mechanized corps, with over 2,500 tanks, were massed to take part in a concentric counter-attack through the flanks of Panzer Group 1; the intention was to attempt a pincer movement from the north and south that met west of Dubno in order to trap units of the 6th and 17th German Armies on the northern flank of Army Group South. To achieve this, the 8th Mechanized Corps was transferred from the command of the 26th Army, positioned to the south of the 6th Army, placed under the command of N. I. Muzychenko's 6th Army; this brought all the mobile assets of the Southwestern Front to bear against the base of von Kleist's thrust toward Kiev. The primary German infantry formation operating on this sector of the front, IV Army Corps of the 17th Army were advancing south-east with the objective of cutting Lviv-Kiev railway line.
At the beginning of Operation Barbarossa, German armor was composed of a mix of Czech and German tanks, as well as small numbers of captured French and British tanks. Furthermore, nearly 50% of the tanks deployed by the Wehrmacht were the obsolete Panzer I and Panzer II light tanks. Of the 4000 armored vehicles available to the Wehrmacht, only 1400 were the new Panzer III and Panzer IV. In the first few hours of the invasion, German commanders were shocked to find that some Soviet tanks were immune to all anti-tank weapons in use by the Wehrmacht. During pre-war exercises, Heinz Guderian noted that on their own, tanks were vulnerable to infantry. Furthermore, he noted that tanks lacked the heavy caliber weapons needed to knock out reinforced concrete bunkers and fortified positions, a role that could only be performed by heavy artillery or air strikes. While dispersing tanks among infantry formations solved many of the tank's weaknesses, it negated some of their strengths. Therefore, German military theorists concluded that to reach their full potential, armored units needed to be concentrated in their own formations and integrated with mobile artillery, mobile infantry, close air support.
Lastly, Guderian concluded that in order for tanks to be at their peak effectiveness, all armored vehicles must be equipped with radios so that each tank commander could hear instructions from the unit commander allowing each tank to work with all others in an organized fashion. At the beginning of June, the Red Army included over 19,000 tanks in their inventory, most of them light tanks such as the T-26 or BT-7; the front armor of the T-26 was just 15mm thick, the BT-7, just 22mm, offering no protection against any anti-tank weapon at any range. Furthermore, the poor design of Soviet shells meant that most rounds shattered on contact, rather than penetrating. More modern tanks, such as the KV-1 and the T-34, were only beginning to roll off production lines and were not available in anywhere near the numbers that were needed to throw back the German advance. During the interwar years, far sighted military theorists such as Mikhail Tukhachevsky came to similar conclusions as Heinz Guderia
Lake Ladoga is a freshwater lake located in the Republic of Karelia and Leningrad Oblast in northwestern Russia, in the vicinity of Saint Petersburg. It is the largest lake in Europe, the 14th largest freshwater lake by area in the world. Ladoga Lacus, a methane lake on Saturn's moon Titan, is named after the lake. In one of Nestor's chronicles from the 12th century he mentions a lake called "the Great Nevo", a clear link to the Neva River and furthermore, to Finnish nevo "sea" or neva "bog, quagmire". Ancient Norse sagas and Hanseatic treaties both mention a city made of lakes named Old Norse Aldeigja or Aldoga. Since the beginning of the 14th century this hydronym was known as Ladoga. According to T. N. Jackson, it can be taken "almost for granted, that the name of Ladoga first referred to the river the city, only the lake." Therefore, he considers the primary hydronym Ladoga to originate in the eponymous inflow to the lower reaches of the Volkhov River whose Finnic name was Alodejoki "river of the lowlands".
The Germanic toponym was soon borrowed by the Slavic population and transformed by means of the Old Russian metathesis ald- → lad- to Old East Slavic: Ладога. The Old Norse intermediary word between Finnish and Old Russian word is supported by archeology, since the Scandinavians first appeared in Ladoga in the early 750s, that is, a couple of decades before the Slavs. Other theories about the origin of the name derive it from Karelian: aalto "wave" and Karelian: aaltokas "wavy". Eugene Helimski by contrast, offers an etymology rooted in German. In his opinion, the primary name of the lake was Old Norse: *Aldauga "old source", associated to the open sea, in contrast to the name of the Neva River which would derive from the German expression for "the new". Through the intermediate form *Aldaugja, Old Norse: Aldeigja cam about, referring to "Ladoga"; the lake has an average surface area of 17,891 km2. Its north-to-south length is 219 km and its average width is 83 km. Basin area: 276,000 km2, volume: 837 km3.
There are around 660 islands, with a total area of about 435 km2. Ladoga is, on average, 5 m above sea level. Most of the islands, including the famous Valaam archipelago and Konevets, are situated in the northwest of the lake. Separated from the Baltic Sea by the Karelian Isthmus, it drains into the Gulf of Finland via the Neva River. Lake Ladoga is navigable, being a part of the Volga-Baltic Waterway connecting the Baltic Sea with the Volga River; the Ladoga Canal bypasses the lake in the southern part. The basin of Lake Ladoga includes 3,500 rivers longer than 10 km. About 85% of the water inflow is due to tributaries, 13% is due to precipitation, 2% is due to underground waters. Geologically, the Lake Ladoga depression is a syncline structure of Proterozoic age; this "Ladoga–Pasha structure", as it known, hosts Jotnian sediments. During the Pleistocene glaciations the depression was stripped of its sedimentary rock fill by glacial overdeepening. During the Last Glacial Maximum, about 17,000 years BP, the lake served as a channel that concentrated ice of the Fennoscandian Ice Sheet into an ice stream that fed glacier lobes further east.
Deglaciation following the Weichselian glaciation took place in the Lake Ladoga basin between 12,500 and 11,500 radiocarbon years BP. Lake Ladoga was part of the Baltic Ice Lake, a historical freshwater stage of Baltic Sea, it is possible, though not certain, that Ladoga was isolated from it during regression of the subsequent Yoldia Sea brackish stage. The isolation threshold should be at Heinjoki to the east of Vyborg, where the Baltic Sea and Ladoga were connected by a strait or a river outlet at least until the formation of the River Neva, even much until the 12th century AD or so. At 9,500 BP, Lake Onega draining into the White Sea, started emptying into Ladoga via the River Svir. Between 9,500 and 9,100 BP, during the transgression of Ancylus Lake, the next freshwater stage of the Baltic, Ladoga became part of it if they hadn't been connected before. During the Ancylus Lake subsequent regression, around 8,800 BP Ladoga became isolated. Ladoga transgressed in its southern part due to uplift of the Baltic Shield in the north.
It has been hypothesized, but not proven, that waters of the Litorina Sea, the next brackish-water stage of the Baltic invaded Ladoga between 7,000 and 5,000 BP. Around 5,000 BP the waters of the Saimaa Lake penetrated Salpausselkä and formed a new outlet, River Vuoksi, entering Lake Ladoga in the northwestern corner and raising its level by 1–2 m; the River Neva originated when the Ladoga waters at last broke through the threshold at Porogi into the lower portions of Izhora River a tributary of the Gulf of Finland, between 4,000 and 2,000 BP. Dating of some sediments in the northwestern part of Lake Ladoga suggests it happened at 3,100 radiocarbon years BP; the Ladoga is rich with fish. 48 forms of fish have been encountered in the lake, including roach, carp bream, European perch, endemic v
Siege of Leningrad
The Siege of Leningrad was a prolonged military blockade undertaken from the south by the Army Group North of Nazi Germany against the Soviet city of Leningrad on the Eastern Front in World War II. The Finnish army invaded from the north, co-operating with the Germans until they had recaptured territory lost in the recent Winter War, but refused to make further approaches to the city; the siege started on 8 September 1941. Although the Soviet forces managed to open a narrow land corridor to the city on 18 January 1943, the siege was not lifted until 27 January 1944, 872 days after it began, it was one of the longest and most destructive sieges in history, the costliest in casualties suffered. Some historians classify it as genocide. Leningrad's capture was one of three strategic goals in the German Operation Barbarossa and the main target of Army Group North; the strategy was motivated by Leningrad's political status as the former capital of Russia and the symbolic capital of the Russian Revolution, its military importance as a main base of the Soviet Baltic Fleet, its industrial strength, housing numerous arms factories.
By 1939, the city was responsible for 11% of all Soviet industrial output. It has been reported that Adolf Hitler was so confident of capturing Leningrad that he had invitations printed to the victory celebrations to be held in the city's Hotel Astoria. Although various theories have been put forward about Germany's plans for Leningrad, including renaming the city Adolfsburg and making it the capital of the new Ingermanland province of the Reich in Generalplan Ost, it is clear Hitler's intention was to utterly destroy the city and its population. According to a directive sent to Army Group North on 29 September, "After the defeat of Soviet Russia there can be no interest in the continued existence of this large urban centre. Following the city's encirclement, requests for surrender negotiations shall be denied, since the problem of relocating and feeding the population cannot and should not be solved by us. In this war for our existence, we can have no interest in maintaining a part of this large urban population."Hitler's ultimate plan was to raze Leningrad to the ground and give areas north of the River Neva to the Finns.
Army Group North under Field Marshal Wilhelm Ritter von Leeb advanced to Leningrad, its primary objective. Von Leeb's plan called for capturing the city on the move, but due to Hitler's recall of 4th Panzer Group, von Leeb had to lay the city under siege indefinitely after reaching the shores of Lake Ladoga, while trying to complete the encirclement and reaching the Finnish Army under Marshal Carl Gustaf Emil Mannerheim waiting at the Svir River, east of Leningrad. Finnish military forces were north of Leningrad, while German forces occupied territories to the south. Both German and Finnish forces had the goal of encircling Leningrad and maintaining the blockade perimeter, thus cutting off all communication with the city and preventing the defenders from receiving any supplies – although Finnish participation in the blockade consisted of recapture of lands lost in the Winter War. Thus, it is argued that much of the Finns participation was defensive; the Germans planned on lack of food being their chief weapon against the citizens.
On Friday, 27 June 1941, the Council of Deputies of the Leningrad administration organised "First response groups" of civilians. In the next days, Leningrad's civilian population was informed of the danger and over a million citizens were mobilised for the construction of fortifications. Several lines of defences were built along the city's perimeter to repulse hostile forces approaching from north and south by means of civilian resistance. In the south, the fortified line ran from the mouth of the Luga River to Chudovo, Uritsk and through the Neva River. Another line of defence passed through Peterhof to Gatchina, Pulkovo and Koltushy. In the north the defensive line against the Finns, the Karelian Fortified Region, had been maintained in Leningrad's northern suburbs since the 1930s, was now returned to service. A total of 306 km of timber barricades, 635 km of wire entanglements, 700 km of anti-tank ditches, 5,000 earth-and-timber emplacements and reinforced concrete weapon emplacements and 25,000 km of open trenches were constructed or excavated by civilians.
The guns from the cruiser Aurora were moved inland to the Pulkovo Heights to the south of Leningrad. The 4th Panzer Group from East Prussia took Pskov following a swift advance and managed to reach Novgorod by 16 August; the Soviet defenders fought to the death, despite the German discovery of the Soviet defence plans on an officer's corpse. After the capture of Novgorod, General Hoepner's 4th Panzer Group continued its progress towards Leningrad. However, the 18th Army – despite some 350,000 men lagging behind – forced its way to Ostrov and Pskov after the Soviet troops of the Northwestern Front retreated towards Leningrad. On 10 July, both Ostrov and Pskov were captured and the 18th Army reached Narva and Kingisepp, from where advance toward Leningrad continued from the Luga River line; this had the effect of creating siege positions from the Gulf of Finland to Lake Ladoga, with the eventual aim of isolating Leningrad from all directions. The Finnish Army was expected to advance along the eastern shore of Lake Ladoga.

Siege of Odessa (1941)
The Siege of Odessa, known to the Soviets as the Defence of Odessa, lasted from 8 August until 16 October 1941, during the early phase of Operation Barbarossa, the Axis invasion of the Soviet Union during World War II. Odessa was a port on the Black Sea in the Ukrainian SSR. On 22 June 1941, the Axis powers invaded the Soviet Union. In August, Odessa became elements of the German 11th Army. Due to the heavy resistance of the Soviet 9th Independent Army and the formed Separate Coastal Army, supported by the Black Sea Fleet, it took the Axis forces 73 days of siege and four assaults to take the city. Romanian forces suffered 93,000 casualties, against Red Army casualties estimated to be between 41,000 and 60,000. On 27 July 1941, Hitler sent a letter to General Ion Antonescu in which he recognised the Romanian administration of the territory between the Dniester and the Bug rivers; the Romanian Third Army had crossed the Dniester on 17 July. Lieutenant-general Nicolae Ciupercă's Fourth Army advanced over the river on 3 August, with the 5th Corps, comprising the 15th Infantry Division and 1st Cavalry Brigade, joined by the 1st Armored Division.
On 8 August, the Romanian General Staff issued the Operative Directive No. 31 instructing the 4th Army to occupy Odessa off the march. It was thought that the city garrison, outnumbered, would surrender quickly. Odessa was fortified by three defensive lines and, thanks to the presence of the Soviet Black Sea Fleet, could not be surrounded; the first line was 80 km long and situated 25–30 km from the city. The second and main line of defense was about 30 km long; the third and last line of defense was organized inside the city itself. The forces that manned the fortifications were made up of the 25th and 95th Rifle Divisions, the 2nd Cavalry Division, the 421st Rifle Division, the 54th Rifle Regiment and an NKVD Regiment; the Red Army had 240 artillery pieces in the area. Air support was provided by the 69th Fighter Aviation Regiment, two seaplane squadrons and one bomber squadron. Other fighters joined the defenders, as did an Il-2 squadron; the defense of Odessa lasted 73 days from 5 August to 16 October 1941.
On 10 August, in the sector of the 3rd Corps, the bulk of the 7th Infantry Division reached Elssas, while the 1st Guard Division arrived on the alignment Strassburg – Petra Evdokievka. In the sector of the 5th Corps, the 1st Armored Division broke through Odessa's first line of defense; that evening, the Romanian division reached the second line of defense. The 1st Cavalry Brigade joined the 1st Armored Division. At the same time, the 10th Dorobanţi Regiment overran the Soviet forces at Lozovaya; the 4th Army closed the circle around Odessa, but the offensive was temporarily stopped by Antonescu on 13 August to strengthen the line west of the Hadjibey bank. The offensive resumed on 16 August, as Romanian troops attacked along the entire line, capturing Odessa's water reservoirs on 17 August; the Soviet forces put up a stubborn resistance, launching repeated counter-attacks and taking heavy casualties. The Royal Romanian Air Force supported the ground troops, disrupting Soviet naval traffic to and from Odessa, destroying an armored train on 20 August.
By 24 August, despite constant attacks, the Romanians were bogged down in front of the Soviets' main line of defense. The 4th Army had suffered 27,307 casualties, including 5,329 killed in action; the Soviets were weakened, thanks to the capture of Kubanka, Romanian heavy artillery now threatened the port of Odessa. Over the next three days, there was a lull in the fighting. On 28 August, the Romanians resumed their offensive, reinforced by a German assault battalion and ten heavy artillery battalions; the 4th, 11th and 1st Army Corps advanced towards Gnileakovo and Vakarzhany, only to be pushed back in some areas by a strong Soviet counterattack the following day. On 30 August the Romanians retook the initiative, but gained little ground. Hitler and the German High Command noted that'Antonescu using at Odessa the tactics of the First World War,' crudely depending upon infantry to make unsupported frontal attacks against Soviet trench line defenses; the Soviets temporarily were driven back by nightfall.
Soviet troops in Vakarzhany were encircled and continued to fight until 3 September, when combined German and Romanian infantry stormed the village. On 3 September, General Ciupercă submitted a memoir to by-now Marshal Antonescu, highlighting the poor condition of the front-line divisions, which were exhausted after nearly a month of continuous fighting, he proposed a reorganization of six divisions, which would be split into 2 corps and supported by 8 heavy artillery battalions. These units would attack in a single area to break through the Soviet line; the memoir however, was rejected by both Antonescu and Brigadier-General Alexandru Ioaniţiu, chief of the Romanian General Staff, who argued that an attack in a single direction would leave the rest of the Romanian line too exposed. Marshal Antonescu subsequently issued a new directive calling for attacks between Tatarka and Dalnik, Gniliavko and Dalnik, to be made by the 11th and 3rd Corps, respectively. Ioaniţiu forwarded a note to Major-General Arthur Hauffe, chief of the German military mission to Romania, informing him of the situation at Odessa and requesting assistance in the form of aircraft and several pioneer battalions.
Although the Royal Romanian Air Force enjoyed some success against the Soviets ground and air forces, it was ill-equipped for anti-shipping raids, the Sov
