The Van Alstyne's Regiment of Militia, also known as the 7th Albany County Militia Regiment, was called up in July, 1777 at Kinderhook, New York to reinforce Gen. Horatio Gates's Continental Army during the Saratoga Campaign. The regiment served in Brigadier General Abraham Ten Broeck's Brigade. With the defeat of General John Burgoyne's British Army on October 17, 1777, the regiment stood down. It is uncertain whether the regiment participated in the October 7 Battle of Bemis Heights, and if it did, whether the entire regiment was there. It is unclear whether Van Alstyne's regiment reached Saratoga before October 7. Historian Borden Mills notes that Ten Broeck's brigade was clearly not at full strength on the day of battle when his return for October 16, 1777 is compared to a later return listing his entire strength.
