CLIO fought up river until the waters became too shallow, he was then detached to command a Calcutta River Police launch towing two Suez Canal horse boats, each armed with a large gun, last used during the Boer War. They bombarded Turkish front lines, came under heavy fire, and attempted to capture Baghdad. Philip Gunn went on to gain a commission and served as a captain in World War II.
