How did the leadership of George Washington contribute to the war effort? How did Baron von Steuben and Marquis de Lafayette contribute?

1. Despite having little experience in commanding large, conventional military forces, Washington's strong leadership presence and fortitude held the American military together long enough to secure victory at Yorktown and independence for his new nation.

2. Steuben also worked with Alexander Hamilton and the Marquis de Lafayette to create a training manual for the Continental Army. Known as the Blue Book, the manual guided the American army all the way through the War of 1812.
