"Hitler wanted to invade Britain and had the forces to subdue it as he had Germany’s other victims, if he could get his troops across the Channel. Germany had no amphibious landing craft or any of the components the Allies would later use for their own crossing; nevertheless, Hitler believed Britain could be conquered if the RAF (Royal Air Force) was destroyed, or at least neutralized. Starting in early July, Reichsmarschall Hermann Göering, ordered the Luftwaffe to begin the bombing campaign. The attacks intensified after the Germans established bases in France and the Low Countries. For nearly five months, the Luftwaffe bombed ports, shipping, airfields, factories, and cities."
