These colors were captured by the Hessians either on August 27, 1776, at the Battle of Long Islands, or Oct. 28, 1776, at the Battle of White Plains. A German account, listing the earlier date, belittles the skill of the American troops who surrendered under this flag, but it was only a few weeks later that the same Hessians under Colonel Rall surrendered to General Washington at Trenton, Dec. 26, 1776. The design on the flag is taken from an undated engraving."These colors were captured by the Hessians either on August 27, 1776, at the Battle of Long Islands, or Oct. 28, 1776, at the Battle of White Plains.
