	5 October	End of resistance in Poland (Second World War)
	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.
1940	16 February	The Altmark incident saw a British destroyer rescue 299 British prisoners from the German supply ship Altmark in Norwegian water.

	23-26 May	The siege of Calais saw some of the most desperate fighting during the German campaign in the west in 1940.

	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
	3-8 May	The battle of the Coral Sea ended with the first major Japanese setback of the Second World War, and marked the end of the period of rapid Japanese expansion across the Pacific that began after the attack on Pearl Harbor.
	26 May-14 June	The battle of Gazala (26 May-14 June 1942) was Rommel's most impressive victory in North Africa, and saw him force the British to abandon the defences of the Gazala Line and retreat back towards the Egyptian frontier.

	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.

	23 October-4 November	The second battle of El Alamein (23 October-4 November 1942) was Montgomery's first great offensive victory, and forced Rommel to begin a retreat that didn't end until he had reached the Mareth Line in Tunisia, ending any last Axis hopes of conquering Egypt.
	26 October	The battle of the Santa Cruz Islands (26 October 1942) was an indecisive carrier battle during the Guadalcanal campaign that ended with one American carrier sunk and two Japanese carriers damaged, but that had little impact on the fighting on the island.

	12-25 March	The battle of Manus (12-25 March 1944) saw the Americans capture the largest of the Admiralty Islands, securing their control of the massive Seeadler Harbour, which then became an important naval base for the rest of the Second World War.

	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.

	17 May-2 September	The battle of Lone Tree Hill or Wakde-Sarmi (17 May-2 September 1944) was a hard-fought contest for control of a strip of the New Guinea coast near the island of Wakde, and saw the Americans eventually win control of a large enough area for them to use as a staging post on the way to further advances.
	17-21 May	The battle of Wakde Island (18-21 May 1944) was part of a wider American offensive carried out in order to protect the western flanks of their newly captured position at Hollandia, on the north coast of New Guinea.
	27 May-29 July	The battle of Biak Island (27 May- 29 July 1944) was one of the most costly of MacArthur's leapfrogging attacks on the north coast of New Guinea and saw a well dug-in Japanese garrison hold out for several months longer than originally expected.
	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
	8-13 June	The small town of Carentan occupied a pivotal position between Omaha and Utah Beaches, and its capture was one of the most important American priorities in the days immediately after D-Day
	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.
	10 July-25 August	The battle of the Driniumor River (10 July -25 August 1944) was a rare large scale Japanese counterattack on New Guinea and saw troops sent west from Wewak attack the American lines east of Aitape, achieving some early successes before being repulsed with heavy losses.
	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.

	12-16 October	The battle off Formosa (12-16 October 1944) was an air battle between Japanese naval aircraft based on Formosa and the aircraft of the US 3rd Fleet that ended with an overwhelming American victory that crippled Japanese naval air power just days before the battle of Leyte Gulf (23-26 October 1944).
	22 October	Last Japanese resistance on Angaur ends.
	22-26 October	The battle of Leyte Gulf (22-26 October 1944) was one of the largest and most complex naval battles in history and ended as a massive American victory that effectively destroying the fighting capability of the Japanese navy.
	23-24 October	The battle of the Sibuyan Sea (23-24 October 1944) was the opening phase of the battle of Leyte Gulf and saw American submarines and carrier aircraft attack Admiral Kurita's I Striking Force, sinking the massive battleship Musashi.
	25 October	The battle of Cape Engano (25 October 1944) was a one-sided American victory that saw Admiral Halsey's 3rd Fleet sink four Japanese aircraft carriers, but at the same time exposing the invasion shipping in Leyte Gulf to a possible Japanese attack. 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.
