Entry of Slovakia into the war against Poland, 1 September 1939
On the Wehrmacht’s side the Slovak Army invaded both Polish (1939) and Soviet territory (1941), being mainly engaged on German initiative. In fact, the war destroyed the traditional pillar of Slovak policy. Germany rewarded Slovakia for its participation by returning areas occupied by Poland in 1920, 1924 and 1938, although this was weak consolation for areas occupied by Hungary. However, the Slovaks also fought on the anti-Nazi side: in Poland, during the war in various countries, and on the western and eastern fronts.
