full_context: Document 1: Battle of Kursk: The Battle of Kursk was a Second World War engagement between German and Soviet forces on the Eastern Front near Kursk (450 km south-west of Moscow) in the Soviet Union during July and August 1943. The battle began with the launch of the German offensive, Operation Citadel (German: "Unternehmen Zitadelle" ), on 5 July, which had the objective of pinching off the Kursk salient with attacks on the base of the salient from north and south simultaneously. After the German offensive stalled on the northern side of the salient, on 12 July the Soviets commenced their Kursk Strategic Offensive Operation with the launch of Operation Kutuzov (Russian: Кутузов ) against the rear of the German forces in the northern side. On the southern side, the Soviets also launched powerful counterattacks the same day, one of which led to a large armoured clash, the Battle of Prokhorovka. On 3 August, the Soviets began the second phase of the Kursk Strategic Offensive Operation with the launch of Operation Polkovodets Rumyantsev (Russian: Полководец Румянцев ) against the German forces in the southern side of the Kursk salient.
Document 2: Battle of Radzymin (1944): The Battle of Radzymin was one of a series of engagements between the Red Army's 1st Byelorussian Front and the German Army's XXXIXth Panzer Corps that occurred as part of the Lublin-Brest Offensive between 1 and 10 August 1944 at the conclusion of the Belorussian strategic offensive operation near the town of Radzymin in the vicinity of Warsaw, part of which entailed a large tank battle at Wołomin.

Document 3: List of Soviet divisions 1917–45: The Soviet Union's Red Army raised divisions during the Russian Civil War, and again during the interwar period from 1926. Few of the Civil War divisions were retained into this period, and even fewer survived the reorganization of the Red Army during the 1937–1941 period. During the Second World War 400 'line' rifle divisions (infantry), 129 Soviet Guards rifle divisions, and over 50 cavalry divisions as well as many divisions of other combat support arms were raised in addition to the hundreds of divisions that existed in the Red Army before Operation Barbarossa. Almost all the pre-war mechanized and tank divisions were disbanded during the war. There were also Red Air Force aviation divisions, and the NKVD divisions which also took part in fighting. However, in contrast to Wikipedia's reasonably complete descriptions of U.S., British, and German divisions, only a few Soviet divisions have articles here, mostly because the detailed histories have either not been translated from Russian or have not been fully released from the official archives.

Document 4: Siege of Mogilev: The Siege of Mogilev was a three-week encirclement of Mogilev undertaken by German troops, part of the Battle of Smolensk. After the beginning of Operation Barbarossa, the German invasion of the Soviet Union, German troops broke through Soviet lines. Mogilev was heavily fortified and bypassed by German tank forces. German infantry steadily reduced the pocket, and by late July, the defending Soviet troops had run out of ammunition and other necessary supplies. As a result, Soviet commander Fyodor Bakunin went against orders and ordered a breakout. A small number of Soviet troops were able to reach Soviet lines, and 35,000 were reported captured by German troops. The defense of Mogilev tied down four German infantry divisions, delaying their attack on Gomel for a week.

Document 10: Battle of Raseiniai: The Battle of Raseiniai (23–27 June 1941) was a large tank battle that took place in the early stages of Operation Barbarossa, the German invasion of the Soviet Union. The battle was fought between the elements of the German 4th Panzer Group (General Erich Hoepner) and the Soviet 3rd Mechanized Corps (Major General Alexey Kurkin) with the 12th Mechanised Corps (Major General Nikolai Shestapolov), in Lithuania, 75 km north-west of Kaunas. The commander of the Soviet Northwestern Front, Colonel General Fyodor Kuznetsov, tried to contain and destroy the German troops that had crossed the Neman River (Nemunas) but was unable to prevent them from advancing. The result of the battle was the destruction of most of the Soviet armoured forces of the Northwestern Front, which cleared the way for the Germans to attack towards the crossings of the Daugava River (Western Dvina). The fighting around Raseiniai was one of the main battles of the initial phase of Operation Barbarossa, referred to in Soviet historiography as the Border Defensive Battles (22–27 June 1941) and formed part of the larger Soviet Baltic Strategic Defensive Operation.
Document 11: Operation Citadel: Operation Citadel (German: "Unternehmen Zitadelle" ) was a German offensive operation against Soviet forces in the Kursk salient during the Second World War on the Eastern Front that initiated the Battle of Kursk.

The German offensive was countered by two Soviet counter-offensives, Operation Polkovodets Rumyantsev (Russian: Полководец Румянцев ) and Operation Kutuzov (Russian: Кутузов ). For the Germans, the battle was the final strategic offensive that they were able to launch on the Eastern Front. As the Allied invasion of Sicily began Adolf Hitler was forced to divert troops training in France to meet the Allied threats in the Mediterranean, rather than use them as a strategic reserve for the Eastern Front. Germany's extensive loss of men and tanks ensured that the victorious Soviet Red Army enjoyed the strategic initiative for the remainder of the war.
