Answer:
On September 1, 1939, just before Adolf Hitler's invasion of Poland that marked the beginning of World War II, Zygmunt Klukowski, a young Polish doctor, confided in his diary that everyone was talking about war. "Everybody," he continued, "is sure that we will win." The reality was startlingly different.
Nazi Germany's war with Poland, begun on September 1, was an uneven contest. Five German armies with 1.5 million men, 2,000 tanks, and 1,900 modern aircraft faced fewer than a million Polish troops with less than 500 aircraft and a small number of armored vehicles. In addition, German planning and technical support -- and German understanding of the importance of modern tactical airpower -- gave the aggressor great advantages.Nazi Germany's invasion of Poland on 1 September 1939, and Britain and France's declaration of war on Germany two days later marks the beginning of World War II. After the declaration of war, western Europe saw very little land or air active military confrontation at first, and the period was termed the " Phoney War ".
