Whitehead torpedo

The Whitehead torpedo was the first self-propelled or "locomotive" torpedo developed. It was perfected in 1866 by Robert Whitehead from a design conceived by Giovanni Luppis of the Austro-Hungarian Navy, it was driven by a three-cylinder compressed-air engine invented and made by Peter Brotherhood. Many naval services procured the Whitehead torpedo including the US Navy; this early torpedo proved itself in combat during the Russo-Turkish War when, on January 16, 1878, the Ottoman ship Intibah was sunk by Russian torpedo boats carrying Whiteheads, though this story has been disputed in one book. The term "torpedo" comes from the Torpedo fish, a type of ray that delivers an electric shock to stun its prey. During the 19th century, an officer of the Austrian Marine Artillery conceived the idea of using a small boat laden with explosives, propelled by a steam or an air engine and steered by cables to be used against enemy ships. Luppis had a model of the device built. Dissatisfied with the device, which he called the "coast-saver", Luppis turned to Robert Whitehead, who worked for Stabilimento Tecnico Fiumano, a factory in Fiume, present-day Croatia.

In about 1850 the Austrian Navy asked Whitehead to develop this design into a self-propelled underwater torpedo. Whitehead developed what he called the Minenschiff: an 11-foot-long, 14-inch-diameter torpedo propelled by compressed air and carrying an explosive warhead, with a speed of 7 knots and the ability to hit a target up to 700 yards away. In 1868, Whitehead introduced a solution to the stability problem for his torpedo: Pendulum-and-hydrostat control, contained in its Immersion Chamber; the Austrian Navy bought the manufacturing rights to the Whitehead torpedo in 1869. By 1870 Whitehead's torpedoes were running at 17 knots. Still, there remained the problem of course correction: returning the torpedo to its correct course after it had deviated due to wind or wave action; the solution was in the form of the gyroscope gear, patented by Ludwig Obry, the rights to, bought by Whitehead in 1896. In 1868, Whitehead offered two types of torpedoes to the world's navies: one was 11 feet, seven inches in length with a diameter of 14 inches.

It weighed 346 pounds and carried a 40-pound warhead. The other was 14 feet long with a 16-inch diameter, it carried a 60-pound warhead. Both models could do 8-10 knots with a range of 200 yards; the United States Navy started using the Whitehead torpedo in 1892 after an American company, E. W. Bliss, secured manufacturing rights; as manufactured for the US Navy, the Whitehead torpedo was divided into four sections: the head, the air flask, the after-body and the tail. The head contained the explosive charge of guncotton; the air flask was constructed from heavy forged steel. The other parts of the shell of the torpedo were made of thin sheet steel; the interior parts were constructed out of bronze. The torpedo was launched below the waterline from a tube, using air or gunpowder discharge. In 1871, the Royal Navy bought manufacturing rights, started producing the torpedo at the Royal Laboratories at Woolwich, England; the Royal Navy fitted the Whitehead torpedo from HMS Holland 1 onwards. The French, Italian, Russian navies soon followed suit and began acquiring the Whitehead torpedo.

By 1877, the Whitehead torpedo was attaining speeds of 18 mph for ranges of 830 yards. By the 1880s, more of the world's navies acquired the Whitehead and began deploying torpedo boats to carry them into battle and engineers began to envision submarines armed with Whitehead torpedoes. In 1904, British Admiral Henry John May commented, "but for Whitehead, the submarine would remain an interesting toy and little more"; the last known operational use of a Whitehead torpedo was during the Battle of Drøbak Sound on the 9th of April 1940. Two torpedoes were fired from a torpedo battery in the Oslofjord at the German cruiser Blücher; this finished the ship off after it had been damaged by cannon fire from Oscarsborg.

Rajputana Agency

The Rajputana Agency was a political office of the British Indian Empire dealing with a collection of native states in Rajputana, under the political charge of an Agent reporting directly to the Governor-General of India and residing at Mount Abu in the Aravalli Range. The total area of the states falling within the Rajputana Agency was 127,541 square miles, with eighteen states and two estates or chiefships. Mewar Residency, with headquarters at Udaipur, dealt with the state of Mewar, a salute state entitled to a hereditary gun salute of 19 guns. Western Rajputana States Agency, part of Mewar Residency until 1906, when it was separated, covered three salute states: Banswara, title Maharawal, hereditary 15 guns Dungarpur, title Maharawal, hereditary 15 guns Pratapgarh, title Maharawat, hereditary 15 guns Jaipur Residency, with headquarters at Jaipur, dealt with two salute states: Jaipur, title Majaraja, hereditary 17 guns Kishangarh, title Majaraja, hereditary 15 guns as well as the Thikana of Lawa.

Western Rajputana States Residency, with its headquarters at Jodhpur, dealt with: Jodhpur, title Maharaja, hereditary salute of 17 guns Jaisalmer, title Maharaja, hereditary salute of 15 guns Sirohi, title Maharao, hereditary salute of 15 guns Bikaner Agency, with headquarters at Bikaner, dealt with the salute state of Bikaner, title Maharaja, Hereditary salute of 17 guns Alwar Agency, with headquarters at Alwar, dealt with the salute state of Alwar, title Maharaja, hereditary salute of 15 guns Eastern Rajputana States Agency, with headquarters at Bharatpur, dealt with: Bharatpur, title Maharaja, hereditary salute of 17 guns Karauli, title Maharaja, Hereditary salute of 17 guns Dholpur, title Maharaj Rana, hereditary salute of 15 guns Haraoti-Tonk Agency, with headquarters at Deoli, dealt with: Bundi title Maharao, hereditary salute of 17 guns Tonk, title Nawab, hereditary salute of 17 guns Shahpura, title Raja, hereditary salute of 9 guns. Kotah-Jhalawar Agency, with headquarters at Kota, dealt with: Kota, title Maharaja, hereditary salute of 17 guns Jhalawar, title Maharaj Rana, hereditary salute of 13 gunsThe small British province of Ajmer-Merwara was included within the geographical area of Rajputana, but, under direct British rule.

All of the princely states had Hindu rulers, except Tonk, which had a Muslim ruler, most being Rajputs, except two in Eastern Rajputana, Bharatpur State and Dholpur State, which had Jat rulers. Although Rajputs ruled most of the states, they comprised a small minority of the population. Other important castes and tribes of Rajputana were the Brahmins, who traditionally occupied the highest rank among castes, were numerous and influential. In the 1901 census, 7,035,093 persons, or more than 72% of the total population spoke one of the Rajasthani languages. Prior to the Muslim invasions of northern India in the eleventh century, Rajputana was ruled by a number of local dynasties, Chief of these were the Gurjara Pratiharas, who ruled at Kanauj; the Rathore, Chauhan and Kachwahas ruled until Indian independence. These Rajput dynasties were supplanted or subordinated by the Muslim invaders of the 11th century and weakened by internal feuds. At the beginning of the 16th century the Rajput power began to revive, only to be overthrown by the Babur, founder of the Mughal empire at Fatehpur Sikri in 1527.

The clans were either conquered, overawed or conciliated by Akbar, except for the distant Sisodia clan, however, submitted to Jahangir in 1616. From Akbar's accession to Aurangzeb's death in 1707, a period of 151 years, most of North India was under Mughal control. In 16th century Jat Power Rise anf they do battle against aurangzeb in battle of Tilpat, after the Death of Gokula Singh Raja Ram Jat looted Akbar's tomb and dragged Akbar's bones and burned them.aurangzeb's death and the invasion of the Marathas and Nader Shah of Iran led to a triple alliance among the three leading Rajput chiefs, which internal jealousy so weakened that the Marathas, having been called in by the Rathors to aid them, took possession of Ajmer about 1756. By the end of the century nearly the whole of Rajputana had been subdued by the Marathas; the Second Anglo-Maratha War distracted the Marathas from 1807 to 1809, but afterwards Maratha domination of Rajputana resumed. In 1817 the British went to war with the Pindaris, raiders who were based in Maratha territory, which became the Third Anglo-Maratha War, the British government offered its protection to the Rajput rulers from the Pindaris and the Marathas.

The Pindari were defeated, the Afghan adventurer Amir Khan submitted and signed a treaty with the British, making him the ruler of Tonk. By the end of 1818 similar treaties had been executed between Britain; the Maratha Sindhia ruler of Gwalior gave up the district of Ajmer-Merwara to the British, Maratha influence in Rajasthan came to an end. Most of the Jat and Rajput princes remained l
