Paul Ludwig Ewald von KleistPaul Ludwig Ewald von Kleist (8 August 1881 – 13 November 1954) was a German field marshal of the Wehrmacht during World War II. Born into the Prussian noble family von Kleist, Kleist entered the Prussian Army in 1900 and commanded a cavalry squadron during World War I. Kleist joined the Reichswehr of inter-war Germany before being discharged in 1938. Recalled to active duty at the beginning of World War II, Kleist commanded a motorised corps in the Invasion of Poland.
Railway gunA railway gun, also called a railroad gun, is a large artillery piece, often surplus naval artillery, mounted on, transported by, and fired from a specially designed railway wagon. Many countries have built railway guns, but the best-known are the large Krupp-built pieces used by Germany in World War I and World War II. Smaller guns were often part of an armoured train. Only able to be moved where there were good tracks, which could be destroyed by artillery bombardment or airstrike, railway guns were phased out after World War II.
Second Battle of KharkovThe Second Battle of Kharkov or Operation Fredericus was an Axis counter-offensive in the region around Kharkov (Kharkiv, Ukraine) against the Red Army Izium bridgehead offensive conducted 12–28 May 1942, on the Eastern Front during World War II. Its objective was to eliminate the Izium bridgehead over Seversky Donets or the "Barvenkovo bulge" (Барвенковский выступ) which was one of the Soviet offensive's staging areas.
Battle of DunkirkThe Battle of Dunkirk (Bataille de Dunkerque) was fought around the French port of Dunkirk (Dunkerque) during the Second World War, between the Allies and Nazi Germany. As the Allies were losing the Battle of France on the Western Front, the Battle of Dunkirk was the defence and evacuation of British and other Allied forces to Britain from 26 May to 4 June 1940. After the Phoney War, the Battle of France began in earnest on 10 May 1940. To the east, the German Army Group B invaded the Netherlands and advanced westward.
4th Panzer ArmyThe 4th Panzer Army (4. Panzerarmee) (operating as Panzer Group 4 (4. Panzergruppe) from its formation on 15 February 1941 to 1 January 1942, when it was redesignated as a full army) was a German panzer formation during World War II. As a key armoured component of the Wehrmacht, the army took part in the crucial battles of the German-Soviet war of 1941–45, including Operation Barbarossa, the Battle of Moscow, the Battle of Stalingrad, the Battle of Kursk, and the 1943 Battle of Kiev.
