"The truth is that there were two Polish resistance groups - Home Army (Armiya Krayowa) and People Army (Amriya Ludowa)".
Yes, that's truth. But it's truth also, that the AL was a margin in big part collecting casual criminals (they called it not robbery, but "social justice" in action), whereas the AK was a mass movement, something like a regular, undergroun army.
There were also other resistance groups, like National Armed Forces (mainly nationalists), Peasants Battalions, Grey Rows (undergroun scouting) and each of them was much more signifficant than the AL.
The AL was just a Soviet military agency in Poland, peparing what happened in 1944-1946. Later most of them were members of communist Security Service, which was Polish NKVD.
