The Polish Home Army (AK or Armia Krajowa), was one of the two main military organizations of the Polish underground that operated in German-occupied Poland. The other major organization was the Communist-oriented People's Army (Armia Ludowa, known as the People's Guard, or Gwardia Ludowa, before January 1944). The AK, which functioned in all areas of the country from the beginning of the German occupation until January 1945, was linked to the London-based Polish government-in-exile, and shared its political orientation. The first commander of the AK was Stefan Rowecki. After his arrest in 1943, he was replaced by Tadeusz Bor-Komorowski, who served from July 1943 until his capture in September 1944. The final commander was Leopold Okulicki. The AK, which had between 250,000 and 350,000 members by 1944, was responsible for intensive economic and armed sabotage during the German occupation. It carried out thousands of armed raids and intelligence operations, bombed hundreds of railway shipments, and was involved in untold numbers of battles with German police and army units. Its forces were behind the Warsaw Uprising of August 1, 1944 that was suppressed by the Germans only on October 2. The AK provided very limited support for the Jewish population. In February 1942 it formed the Section for Jewish Affairs directed by Henryk Wolinski, which collected information about the situation of Polish Jews, on the basis of which reports were sent to London. It also centralized contacts between Polish and Jewish military organizations. The AK provided the Warsaw ghetto fighters with a small amount of guns and ammunition, and during the ghetto uprising, carried out holding actions outside the ghetto walls. Only a few Jews were actually accepted into the ranks of the AK.

The men are dressed in stolen German uniforms and armed with confiscated German weapons. Pictured from left to right are Wojciech Omyla, Juliusz Bogdan Deczkowski (the donor), and Tadeusz Milewski. Milewski was killed shortly thereafter. Omyla was killed several days later on August 8, 1944. The Zoska battalion liberated 348 Jews from the Gesiowka prison during the uprising.
Juliusz Bogdan Deczkowski was imprisoned from 5 May 1941 until 16 February 1942. During the Warsaw uprising Deczkowski, a member of Zoska battalion of the Armia Krajowa (Home Army), participated in an action to release 348 Jewish men and women from the Gesiowka prison on 5 August 1944.

Armia Krajowa Cross (Home Army Cross; Polish: Krzyż Armii Krajowej) is a Polish military decoration that was introduced by General Tadeusz Bór-Komorowski on 1 August 1966 to commemorate the efforts of the soldiers of the Polish Secret State between 1939 and 1945. The decoration was awarded to soldiers of the Home Army (Armia Krajowa) and of its predecessor organizations (Służba Zwycięstwu Polski, Związek Walki Zbrojnej).
The first recipient (posthumous) was General Stefan Grot–Rowecki.
The award was supported by the Polish government in exile in London and was not recognized by the People's Republic of Poland, which viewed members of mostly anti-communist Armia Krajowa as enemies of the state. After the fall of communism, in 1992 it was recognized by the government of Poland and was awarded by the president of Poland until 8 May 1999.
