Hitler's lightning invasion of Poland in 1939 marked the beginning of World War II in Europe. This was the period when armoured warfare inscribed itself into global consciousness as the Poles desperately sought to stave off the Blitzkrieg. At the heart of the fighting on the ground, large numbers of Nazi Germany's PzKpfw II battled against Poland's better-armed but much less numerous 7TP tank. The two types both possessed unique strengths and weaknesses unlike the 7TP the PzKpfw II was always equipped with radio, which proved critical for command and control purposes in the heat of combat. But the German tank was blighted by thin armour, which could not withstand Polish gunfire at combat ranges. This fully illustrated, detailed work evaluates the qualities and idiosyncrasies of each tank, giving a stark and arresting crewman's-eye-view of the brutal armoured combat at the height of the invasion of Poland.
