The Battle of Britain, also known as the Air Battle for England (German: die Luftschlacht um England) was the first major military campaign fought entirely by air forces. Historians have cited Germany s failure to destroy Britain s air defenses to force an armistice (or even a full surrender) as the first major German defeat of World War II and a crucial turning point in the conflict. In this and other historical simulations of the Second World War I do not decide my hypotheses based on the morals of one ideological faction or another. As a citizen I am a Democrat. I do seek to study the strategy, operational and/or tactical variants for the narrated, analyzed and simulated history. Therefore, in this book, I will dedicate myself to simulating how this first exclusive campaign and air battle in history would have developed if the Luftwaffe command had corrected the main operational flaws listed in my historical analysis. As a military scientific foundation, I will use the lessons learned in Operation Focus (in Hebrew: מבצע מוקד, Mivtza Moked), which was Israel s air attack at the beginning of the Six-Day War in 1967.
