The anti-communist resistance in Poland, also referred to as the Polish anti-communist insurrection fought between 1944 and 1953, was an anti-communist and anti-Soviet armed struggle by the Polish Underground against the Soviet domination of Poland by the Soviet-installed People's Republic of Poland, since the end of World War II in Europe. The guerrilla warfare conducted by the resistance movement formed during the war, included an array of military attacks launched against communist prisons, state security offices, detention facilities for political prisoners, and prison camps set up across the country by the Stalinist authorities.

In January 1945, the pro-Soviet government installed in Poland by the advancing Red Army declared as "illegal" parts of the Polish resistance such as militia/paramilitary units of the Home Army, and ordered its surviving members to come out into the open while guaranteeing them freedom and safety. Many underground fighters decided to lay down their arms and register, but after doing so, some of them were arrested and thrown in prison due to their pasts, which were overlooked during wartime. Thousands of them were tortured and later deported into the Soviet Gulag camp system after being tried, with many deaths (see, the Uroczysko Baran killing fields among similar others).

As a result, many remaining Armia Krajowa (AK) members quickly stopped trusting the new government, and some of them regrouped clandestinely to oppose the new Soviet backed government. They formed various post-AK resistance organisations, such as Wolność i Niezawisłość ("Freedom and Sovereignty"), and liberated hundreds of prisoners. They became known as the "cursed soldiers" of the Polish underground, and most were eventually captured and tried for their crimes or killed by the security services and special assassination squads.

Meanwhile, acting together under the command of Soviet General Ivan Serov, the forces of the NKVD, SMERSH and the Polish communist secret service (UB), which was modelled on the Soviet secret police, began countrywide operations against the members of the Armia Krajowa and other Polish resistance units loyal to the government-in-exile. Approximately 25,000 underground soldiers, including 300 Home Army officers, were arrested, disarmed, and interned before October 1944.Soviet NKVD, at www.warsawuprising.com   On 15 October 1944, Lavrentiy Beria signed Order No. 0012266/44, which established NKVD Division 64, whose only task was to fight against the Polish resistance.

God's Playground: 1795 to the present By Norman Davies   Faced with an unacceptable choice, and knowing about the grave fate of their own leaders (see: Trial of the Sixteen), thousands of soldiers of the Home Army (which was officially disbanded on 19 January 1945) and other organizations decided to continue fighting for freedom after the end of World War II.

Polish anti-communist Insurrection The situation in Poland in the immediate aftermath of World War II has been described as an all-out civil war,Civil war in Poland.

In return, the Stalinist authorities carried out brutal pacifications of partisans and civilians, mass arrests (see: Augustów chase 1945), deportations, as well as executions (see: Mokotów Prison murder, Public execution in Dębica) and many secret assassinations.

The anti-communist movement responded with attacks on NKVD and UB camps, such as the Attack on the NKVD Camp in Rembertów. The underground units often engaged in regular battles with the Soviets and Polish communist forces (see: Battle of Kuryłówka). Resistance units loyal to the Polish government-in-exile did not hesitate to attack even large cities, to free their fellow soldiers kept in various prisons and detention camps across Poland.

List of attacks on communist prisons, camps and state security offices In 2007, the Institute of National Remembrance Commission for the Prosecution of Crimes against the Polish Nation (IPN), published the Atlas of the Independence Underground in Poland 1944–1956, listing scores of armed attacks on communist prisons after World War II, in which hundreds of political prisoners were freed. The most daring assaults were conducted before October 1946.
