Burgoyne sent an expedition under Lieutenant Colonel Friedrich Baum to capture American supplies at Bennington, Vermont. Baum commanded 374 Brunswick infantry and dismounted dragoons, 300 Indians, loyalists, and Canadians, and two 3-pound cannons manned by 30 Hessians. Stark heard about the raid and marched his force to Bennington. Meanwhile, Baum received intelligence that Bennington was held by 1,800 men. On August 14, Baum asked Burgoyne for reinforcements but assured his army commander that his opponents would not give him much trouble. The Brunswick officer then fortified his position and waited for Lieutenant Colonel Heinrich von Breymann's 642 soldiers and two 6-pound cannons to reach him. Colonel Seth Warner also set out with his 350 men to reinforce Stark.
