At Valley Forge

The harvest for the previous year among the Oneidas had produced an abundant amount of corn and knowing that George Washington and his army at Valley Forge were low on supplies, Chief Shenendoah (aka Oskanondohna) sent an expedition to help with the food shortage. [1] Among them was one woman by the name of Polly Cooper. Cooper would also be among a group of people who would choose to stay behind and continue to help the American Army. [2]

She aided not only in caring for the many sickly soldiers but also taught them the nutritional and medicinal purposes of various foods. Most importantly, she showed them how to use hulled corn to make a soup that was an essential part of the Iroquois diet. [3] Cooper was even known to walk among the soldiers during battle to provide water to the soldiers. Polly Cooper and the generous gift of the Oneida certainly helped lead to a victory by George Washington and his troops in leading the British out of Valley Forge and Pennsylvania. [4]

EDIT: several years later, washington ordered general sullivan to burn all the Iroquois towns and crop fields in new york state, including those of the oneida who saved his sorry ***. he earned the name “Town Destroyer”.
