Berling Army: 1943-1945

Further information: Berling Army and Ludowe Wojsko Polskie

After the Anders Army left Soviet controlled territory, and it became more and more apparent that the Soviet forces were able to hold the front against the German invaders without reliance on Western aid (Lend-Lease Act) or temporary allies (like the Polish government-in-exile), the Soviets decided to assume much greater control over the remaining Polish military potential in the USSR (ignoring the agreements signed with the Polish government-in-exile). Increasing numbers of volunteers were denied the opportunity to enlist in the Polish formations, instead they were declared Soviet citizens and assigned to the Red Army. Activities of organisations and people loyal to the Polish government-in-exile, particularly the Polish embassy in Moscow, were curtailed and its assets confiscated. Finally, diplomatic relations between the Soviets and the Polish government-in-exile were severed again as news of the Katyn massacre emerged in 1943.

In 1943 the Soviet Union created in Moscow the Union of Polish Patriots (ZPP) as a communist puppet government designed to counter the legitimacy of the Polish government in exile; the ZPP was led by the pro-Soviet Polish communist Wanda Wasilewska.

At the same time a new army was created - the Ludowe Wojsko Polskie (Polish People's Army, LWP). Its first unit, the 1 Polish Infantry Division (1 Dywizja Piechoty im. Tadeusza Kościuszki), was created in summer 1943, reaching operational readiness by June/July. In August, the Division was enlarged to a corps, becoming the Polish I Corps. It would be commanded by General Zygmunt Berling; other notable commanders included General Karol Świerczewski and Col. Włodzimierz Sokorski. The division with its supporting elements was sent to the Eastern Front in September 1943; one of the most notable battles of that period was the Battle of Lenino, the first major engagement of the Berling Army. By March 1944 the Corps had been strengthened with increasing armoured and mechanical support, and numbered over 30 000 soldiers. In mid-March 1944 the Corps was reorganized into the Polish First Army. The later Soviet-created Polish army units on the Eastern Front included the Second (1945) and the Third Polish Armies (the latter was quickly merged with the second due to recruitment problems), with the number of smaller formations being 10 infantry divisions (numbered from 1st to 10th) and 5 armoured brigades. Plans for a Polish Front were considered but dropped, and the Polish First Army was integrated into the 1st Belorussian Front.

These units were led by Soviet commanders, appointed by the Soviets and fought under Soviet general command (the Second Army, for example, was led by the Soviet general Stanislav Poplavsky). In the Air Force of those formations 90% of officers and engineers were Soviet ones, the situation was similar in armoured formations. In the Polish Second Army they comprised 60% of officers and engineers, and in the 1st 40%. In the command staff and training the percentage of Soviets was about 70 to 85%. Special political officers, almost exclusively made up of Soviets, oversaw the Polish soldiers. The Soviets created also political military police, based on thousands of secret informants called Główny Zarząd Informacji Wojska Polskiego in Polish.

The First Army entered Poland from Soviet territory in 1944. Under Soviet orders it did not advance into Warsaw as the Germans military defence of Warsaw was substantial with combined SS units fighting to the death against the advancing Polish units. (General Zygmunt Berling gave the command to move forward cross the Vistula river into Warsaw. During this episode of heroic fighting against Nazis heavy losses were sustained by the First division while crossing the Vistula river into Warsaw yet it was pivotal in the eventual liberation of Warsaw from Nazi forces. In January 1945, after the Germans had unsuccessfully suppressed the uprising against Polish forces, the 1st Army participated in the Soviet Warsaw offensive that finally ended the Nazi occupation of the ruined city. In April–May 1945 the 1st Army fought in the final capture of Berlin.
