The Alice Dollar incident was an affair involving a United States-flagged merchant ship and an American warship in 1920.
Chinese rebels along the Yangtze River attacked the SS Alice Dollar on July 20, so the gunboat USS Monocacy was assigned to escort the vessel out of the area.
Captain C. D. Gilroy, of USS Monocacy, was informed of the situation and asked to escort the merchant ship back down the river on the next day, July 21.
The Americans again returned fire and shot several more shells and hundreds of bullets into the surrounding hills, forcing the rebels to abandon their attempt.
Captain Gilroy estimated that his ship was fired on 600 times though only 15 bullet holes were counted and two men were slightly wounded.
