In the spring of 1941, shortly before his forces launched their invasion of Russia, Hitler was forced to undertake an assault upon the Balkans. Hitler launched a preemptive strike through Yugoslavia and, thence, to Greece, sweeping both British and local forces in front of them. The second part of this book deals with North Africa, where the Deutches Afrika Korps under Erwin Rommel was formed to support an increasingly beleaguered Italian force. Using contemporary photographs, allied with line drawings and detailed analysis, the author explores how the strategy evolved during these two campaigns.
