40th Army (Soviet Union) - First Formation (World War II)

First Formation (World War II)

It was first formed, after Operation Barbarossa, the German invasion of the Soviet Union, had commenced, from elements of the 26th and 37th Armies under the command of Major General Kuzma Petrovich Podlas in August 1941 at the boundary of the Bryansk Front and the Soviet Southwestern Front. By 25 August 1941 the 135th and 293rd Rifle Divisions, 2nd Parachute Corps, 10th Tank Division, and 5th Anti-Tank Brigade had been assembled to form the force. As part of the Southwestern Front, it then took part in the Battle of Kiev (1941), where the Army was badly shattered, and General-Major Semenchenko's 10th Tank Division was reduced to twenty tanks. By the time of the main German offensive against Moscow at the end of September, 40th Army was on the extreme right flank of Southwestern Front defending the Kursk axis. The German offensive was directed primarily at Soviet forces to the north of 40th Army, though the attack of the German 48th Motorised (Panzer) Corps, which was operating on the extreme southern flank of Second Panzer Group, also hit 40th Army's right flank positions. 40th Army began a slow and steady retreat to the east. By 3 November 40th Army had been driven from Kursk, but by the end of the month it had brought the German advance to a halt near the town of Tim some 50 kilometres further east.

As part of a general winter offensive by the Red Army across the entire Eastern Front, on 1 January 1942 40th Army, by then based on six rifle divisions and two tank brigades, attacked German positions east of Tim. Off 40th Army's right flank the Soviet 13th Army had for several weeks been conducting offensive operations towards Orel, advancing some 50 kilometres to the west and retaking Elets and Kastornoye in the process. The advance of 40th Army was less rapid. By 3 January 40th Army, in conjunction with 21st Army further south, was involved in heavy fighting on the line of the Seym river as the two armies attempted to advance on Kursk and Oboyan respectively. 40th Army retook Tim and advanced to within 30 kilometres of Kursk before being stopped by determined German resistance in mid-January. Thereafter the frontline stabilised west of Tim through the rest of the winter and through the spring. On 3 April 40th Army and its sector of the frontline was assigned to the command of Bryansk Front. On 12 May 1942 Southwestern Front launched a major offensive to retake Kharkov by an encirclement from north and south. At the same time Bryansk Front was preparing an offensive of its own to retake Orel. However, by 16 May the offensive by Southwestern Front north of Kharkov had stalled and Bryansk Front was ordered to divert the bulk of its combat aircraft to 40th Army in the south and to launch an immediate offensive by 40th Army to support Southwestern Front's right wing. However, this hurriedly prepared offensive by 40th Army in the second half of May made little progress.

In June 1942, Operation Blau saw Hoth's Fourth Panzer Army thrust in full force against 40th Army, which had its headquarters overrun by 24th Panzer Division on 29–30 June. The 40th Army fell back from the Kastornoye area back to Voronezh, alongside the 4th, 17th, and 24th Tank Corps. In response, the STAVKA hastened to establish the new Voronezh Front. During July, 40th Army, subordinated to Voronezh Front, was assigned to defend the river Don along the Liski - Pavlovsk sector, positions that it held throughout the remainder of 1942.

On 12 January 1943 40th Army began offensive operations against the left flank of the Hungarian Second Army north of Liski. This offensive was coordinated with an attack by a Soviet tank army further south to surround Axis forces on the Liski - Novaya Kalitva sector of the Don front. By 18 January most of the Hungarian army and an Italian corps had been surrounded east of Alekseyevka. The advance of 40th Army had left the German Second Army in exposed positions at Voronezh and, in a hurriedly prepared offensive coordinated with three other Soviet armies further north, 40th Army struck north on 24 January to surround much of Second Army east of Kastornoye. Having barely completed this operation, on 2 February 40th Army was launched into an offensive on the Kharkov axis to the southwest. It took Novy Oskol on 5 February and reached Belgorod four days later. Continuing to the southwest, 40th Army had reached Akhtyrka northwest of Kharkov by 23 February, but by then a German counter-offensive on the Kharkov axis had developed and 40th Army was pushed back to defensive positions east of Sumy. These defensive positions, which were to form part of the southern face of the Kursk Salient, remained largely unchanged through April, May and June 1943.

On 5 July 1943 Germany's last strategic offensive on the Eastern Front (Operation Citadel) opened with attacks on the northern and southern shoulders of the Kursk Salient. The objective was to envelop and destroy the defending Central and Voronezh Fronts north and south of Kursk. At that time 40th Army, occupying what was expected to be a relatively quiet sector of the frontline facing the left flank of the German Fourth Panzer Army, was based on seven rifle divisions with armoured support. During the Battle of Kursk, where the Army fought as part of Voronezh Front, it transferred a number of reinforcements to 6th Guards Army to help 6th Guards hold back the 48th Panzer Corps, including the 29th Tank Destroyer Brigade and the 1244th and 869th Tank Destroyer Regiments, a total of over 100 antitank guns. 40th Army also transferred a tank brigade to 38th Army at the same time. After the battle, it was involved in the crossing of the Dnepr in September 1943 in conjunction with airborne operations. The Army was later involved in the Battle of Kiev (1943) and in 1944, as part of 2nd Ukrainian Front, actions around the Korsun-Cherkassy Pocket, Kamenets-Podolsky Pocket, and the Uman-Botoshany, Iassy-Kishinev, Bratislava-Brno, and Prague offensives. It also fought in the Battle of Debrecen, at which, due to its low priority, it only had five divisions assigned. 40th Army was disbanded in July 1945.
