Three Reasons for Polish Defeat 1.) Polish forces mobilized too late. The Polish leadership hesitated in making a military decision. Many tanks were unable to fire their first shots. The majority of the Polish Air Force was destroyed before they took off. 2.) Polish defenses were spread too thin along the 800 mile front. The German attack came from the North, South and West. 3.) Britain and France failed to come to the aid of Poland.
