2) How did people help the soldiers at Valley Forge?

Baron Friedrich von Steuben

Explanation:

Baron Friedrich von Steuben, a Prussian military officer, provided important training for the American troops. As the drillmaster of Valley Forge, he taught the soldiers how to use the bayonet, and most importantly, how to re-form lines quickly in the midst of battle.

Valley Forge functioned as the third of eight winter encampments for the Continental Army's main body, commanded by General George Washington, during the American Revolutionary War. In September 1777, Congress fled Philadelphia to escape the British capture of the city. After failing to retake Philadelphia, Washington led his 12,000-man army into winter quarters at Valley Forge, located approximately 18 miles northwest of Philadelphia.
