The 53rd Army was created by a Stavka directive on August 23, 1941. Its immediate task was to occupy Iran[3] in conjunction with the British Army and other Commonwealth armed forces in August and September 1941. The purpose was to secure Iranian oil fields as well as safeguard the shipment of Lend-Lease war material from the US through Iran to the USSR. Units of the 53rd Army crossed the border on August 27, overcame resistance from Iranian border guards, and advanced towards Mashad.[4]
The 53rd Army was reformed on May 1, 1942 from divisions of the 34th Army[6] with the mission of fighting on the Northwestern Front.[1][2] Until March 1943 it fought the German 16th Army in the Demyansk Offensive and unsuccessfully attempted to cut the Ramushevo corridor.[7][8][9] After the German breakout the 53rd Army was transferred to the Stavka reserve on March 22 and then to the Reserve Front on April 10. On April 15, it was transferred a third time, to the Steppe Front, where it received new units and fought in the Battle of Kursk.[6][10] On July 16 its troops took defensive positions on a line from Podolhi to Poidjarug. It fought subsequently in the Battle of Belgorod, pushing back German troops from July 19 onwards.[10]
In August and September 1943 the Army fought in the Belgorod-Kharkov Offensive and the capture of eastern Ukraine.[11] Units of the 53rd Army advanced more than 200 km and in cooperation with other armies captured Kharkov on August 23[8] and Poltava a month later. On October 5 it reached the Dnieper. The 53rd Army forced the Dnieper, captured a bridgehead southeast of Kremenchug, and fought hard until mid-November to retain its foothold on the right bank.[2]
The Army was transferred to the 2nd Ukrainian Front on October 20 and attacked along the Kirovohrad axis. By December 24 it had reached the line of Krasnosele and Znamianka, where it was stopped by German reserves. On January 5, 1944 the attack was resumed and the defending German units were destroyed. At the end of January the 53rd Army fought in the Korsun-Shevchenkovsky Offensive[8] and attacked in the direction of Zlatopol. In the Uman–Botoșani Offensive it captured Balta on March 29, Kotovsk three days later and, at the end of the offensive, a bridgehead on the Dniester near Dubăsari.[12]
At the end of September 1944, the 53rd was on the Hungarian border northeast of Arad.[8] In October it fought in the Battle of Debrecen,[8] during which Army commander German Tarasov was killed on 19 October.[14] In cooperation with the 1st Guards Mechanized Cavalry Group, it broke through German defenses and advanced 100 kilometers to the Tisza near Polgár.[15] Between November 7 and 10, 1944, the 53rd Army forced the Tisza during the Budapest Offensive north of Abádszalók. In conjunction with the 110th Guards Rifle Division and 3rd Guards Airborne Division of the 27th Army it captured Eger on November 30.[16] The 53rd Army then attacked along the Lučenec axis, reached the Hron at the end of February 1945, and then went on the defensive.[2]
During the Bratislava-Brno Operation the 53rd Army crossed the Hron on March 25 and captured Vráble on March 28, Nitra on March 30, Hlohovec on April 1, and Hodonín on April 13. Brno was captured on April 26 in cooperation with the 6th Guards Tank Army and 1st Guards Cavalry Mechanized Group.[8] In the last days before the German surrender the 53rd Army fought in the Prague Offensive.[2]
