Sergeant Stubby was smuggled to France with the 102nd Infantry, 26th Yankee Division. He soon became sensitive to gas exposure, enabling him to alert the soldiers to gas attacks, and also located injured men on the battlefield by listening for soldiers who spoke English. He once caught a German spy who was mapping out the Allied trenches, and refused to let the man escape until U.S. soldiers arrived. He served in a total of 17 battles. After the war, he had become a celebrity, and led several parades in addition to meeting Presidents Harding and Coolidge.
