American militia fighting on their own soil was arguably the largest technical factor in them winning the war. Americans knew the land they fought on, and therefore knew the best routes to take for supplies, troop movements, and where the British may have been hiding. American militias hired <em>frontiersmen</em>, men who had grown up in the woods and knew how to hunt and travel in them, to fight on their side of the war. This allowed for a huge advantage over the British in the ground battles of the war.
Americans also had something that the British did not: patriotism. The Americans knew that, if they did not win the war, they would have to go back to living under the unfair British rule, if they did not die that is. Americans were able to use this spirit to fight their war harder than the British did.
Americans did not fight England's war. They disregarded the European ideas of a gentleman's war and fought, as the British considered them, dirty. The Americans shot and killed commanding officers, shot and killed their horses, attacked at night and during meal and tea times, and other war strategies that went against how the British had been taught to fight their whole life. This gave Americans a large edge over the British in individual battles.
On June 17, 1940, The defeated French signed an armistice and quit WW II, leaving Britain standing alone against Germany. In the Summer and fall of that year, German and British forces clashed in the skies over Britain in the first all-air battle in history.
A significant turning point in WW II, the Battle of Britain ended when Germany's Luftwaffe failed to gain air superiority over the Royal Air Force . Britain's decisive victory saved the country from a ground invasion from the enemy and proved air power alone could also be used to win a major battle.
