	13 December	The battle of the River Plate is one of the most famous naval battles of the Second World War, despite only involving four ships. Part of its fame came because it took place in the “phoney war” period and part because of the unjustifiably high reputation of the Admiral Graf Spee, the German pocket-battleship involved in the battle.

	10 April-16/17 December	The siege of Tobruk (10 April-16/17 December 1941) saw a beleaguered Allied garrison hold out for eight months against German and Italian attacks, and helped prevent Rommel taking full advantage of his victory in his first offensive, which had seen him conquer Cyrenaica only a few weeks after it had fallen to the British
	15-16 May	Operation Brevity (15-16 May 1941) was a short-lived British offensive carried out to see if the German position east of Tobruk was fragile enough for the siege to be lifted without a major battle.

	28 March	Raid on St. Nazaire denies Germans use of major French drydock

	7 June	Battle of Midway (Pacific Ocean)
	17-21 June	The siege of Tobruk (17-21 June 1942) was one of the more embarrassing British defeats in North Africa, and helped to reduce Churchill's confidence in General Auchinleck's abilities as a commander.

	1-27 July	The first battle of El Alamein (1-27 July 1942) was a series of engagements in the area south of El Alamein in which Rommel's run of victories in 1942 was finally brought to an end. A series of British counterattacks also achieved little, and the battle ended as a stalemate.
	23 July-13 November	The battle of the Kokoda Trail saw the Japanese army reach further south than at any other time during the Second World War, in an attempt to capture Port Moresby, but also marked the point at which Japan’s resources became too stretched to support further offensive operations, and ended as a clear Australian victory.
	August	Start of Battle for Guadalcanal (to February 1943)

The occupation of Allen Island (Ennubirr), 31 January 1944, was one of two simultaneous landings that formed the second stage in the invasion of Roi and Namur in Kwajelein Atoll.

	22-27 April	Operation Reckless, the invasion of Hollandia and Aitape of 22-27 April 1944, was one of the most dramatic leapfrogging operations during the New Guinea campaign, and saw American forces bypass the strong Japanese bases at Wewak and Hansa Bay and capture key bases for MacArthur's planned return to the Philippines The battle of Hollandia (22-27 April 1944) was part of Operation Reckless and saw the Americans leapfrog past a series of Japanese bases to capture a key position on the northern coast of New Guinea, catching the Japanese almost entirely by surprise and winning an unexpectedly easy victory.
	22-24 April	The battle of Aitape (22-24 April 1944) was carried out in support of the larger landings at Hollandia, and was designed to provide a shield against any possible intervention by Japanese forces further to the west at Wewak.

	6 June	The D-Day landings of 6 June 1944 were one of the most significant moments of the Second World War, and marked the point when the combined military force of the Western allies were finally brought to bear fully against Germany. The landings on Utah Beach (6 June 1944) were the most westerly and perhaps the easiest of the D-Day landings, due in part to the actions of the American airborne divisions operating inland from the beach and partly to a strong tide which swept the landing craft a kilometre to the south of their intended landing point The landing on Omaha Beach was the hardest fought and most costly of the D-Day landings, and the one that came closest to failure. A combination of a strong defensive position, rough seas, the loss of most of the supporting tanks and artillery, a too-short naval bombardment and an ineffective aerial bombardment saw the first wave of American troops pinned down on the water's edge, and although by the end of the day the landing was secure the Omaha beachhead was still less than a mile deep. The landing on Gold Beach was one of the more successful of the D-Day landings, and by the end of 6 June the British had penetrated the German's coastal defences and were on the verge of liberating Bayeux, which on 7 June became the first French town to be liberated The landing on Juno Beach was the main Canadian contribution on D-Day, and saw the Canadian 3rd Infantry Division and 2nd Armoured Brigade overcome some of the strongest German defences and a late arrival to achieve the deepest penetration into France of any Allied troops on 6 June The troops landing on Sword Beach on 6 June had the most important task on D-Day – to protect the eastern flank of the entire landing area against the possibility of a major German armoured counterattack from the east, while at the same time taking part in the attack on Caen

	15 June-9 July	The battle of Saipan (15 June-9 July 1944) was the first invasion of the Marianas campaign, and it took nearly a month for US forces to secure the fairly small island.
	22-29 June	The capture of the port of Cherbourg was one of the most important early objectives for the Allies after the D-Day landings
	26-30 June	Operation Epsom (26-30 June 1944) , or the battle of the Odon,was the first major British offensive to be launched after the D-Day landings, and was a successful attempt to force the Germans to concentrate their armoured units against the British and Canadians, at the eastern end of the Normandy beachhead
	2 July-30 August	The battle of Noemfoor (2 July-30 August 1944) was a US amphibious landing carried out in order to make up for slow progress on Biak and the resulting shortage of airfields in western New Guinea.

	21 July-9 August	The battle of Guam (21 July-9 August 1944) saw the Americans reconquer an island that had been in their hands before the war after three weeks of fighting, completing the conquest of the Mariana Islands.
	24 July-1 August	The invasion of Tinian (24 July-1 August 1944) took place three days after the start of the invasion of Guam, and after a week the island had been secured by the Americans.
	30-31 July	The landings at Sansapor (30-31 July 1944) were the last major American offensive of the long New Guinea campaign, and saw them capture a foothold on the Vogelkop Peninsula, at the western end of New Guinea, where they were able to build a medium bomber base to support operations further west.

The battle of the Surigao Straits (25 October 1944) was the last clash between battleships and saw a force of older American battleships crush a Japanese squadron attempting to break into Leyte Gulf. The battle of Samar (25 October 1944) was the nearest the Japanese came to success during the battle of Leyte Gulf and saw a powerful Japanese battleship force come close to destroying a force of American escort carriers.
