 The policy of the occupying power turned quickly harsh towards Ukrainians as well.Some of the Ukrainian nationalists were driven underground, and from that time forward, they fought against the Nazis, but continued also to fight against Poles and Soviet forces (see Ukrainian Insurgent Army).As the Red Army was approaching the city in 1944, on July 21 the local leadership of the Polish resistance Home Army ordered all Polish forces to rise in an armed uprising (see also Operation Tempest).
