Battle of Hel
The Battle of Hel (, literally "the Defense of Hel") was a World War II engagement fought from 1 September to 2 October 1939 on the Hel Peninsula, of the Baltic Sea coast, between invading German forces and defending Polish units during the German invasion of Poland (also known in Polish historiography as the September Campaign). The defense of the Hel Peninsula took place around the Hel Fortified Area, a system of Polish fortifications that had been constructed in the 1930s near the interwar border with the German Third Reich.
