The Capture of Oppy Wood was an engagement on the Western Front during the First World War on 28 June 1917. The Battle of Arras of 1917 ended with the Germans in possession of a fortified wood to the west of the village of Oppy, which overlooked British positions. The wood was 1 acre (0.4 ha) in area and contained many German observation posts, machine-gun nests and trench mortars. New German defensive tactics adopted after the Battle of the Somme of defence in depth and rapid counter-attack, had been enforced on the German 6th Army after the disaster of 9 April, the first day of the Battle of Arras. The British attack of the Third Battle of the Scarpe (3–4 May), was defeated everywhere bar Fresnoy, which was captured by the 1st Canadian Division. The attack on Oppy Wood by the 92nd Brigade of the 31st Division, was a costly failure. The area was defended by the 1st Guard Reserve Division and the 15th Reserve Division, which did not need the support of specialist Eingreif (counter-attack) divisions.

The 92nd Brigade was an infantry formation of the British Army during World War I. It was raised as part of 'Kitchener's Army' and was assigned to the 31st Division. After the original formation was converted into a reserve brigade, the number was transferred to a brigade composed volunteer battalions raised in the city of Kingston upon Hull for 'Kitchener's Army'. It first served in Egypt defending the Suez Canal between January and March 1916. It then left for the Western Front where it was at Serre on the first day of the Battle of the Somme in 1916, though its battalions escaped the worst of the disaster. It continued to serve on the Western Front for the rest of the war, including hard fighting at Oppy Wood, against the German spring offensive and in the final Hundred Days Offensive.
