. The U-boat had been ordered by November 1914 and was launched on 26 April 1915. She was commissioned into the German Imperial Navy on 5 July 1915 as SM ''UC-1''."SM" stands for "Seiner Majestät" ( en, His Majesty's) and combined with the ''U'' for ''Unterseeboot'' would be translated as ''His Majesty's Submarine''. Mines laid by ''UC-1'' in her 80 patrols were credited with sinking 41 ships. ''UC-1'' disappeared after 18 July 1917.UC-1 was sunk on 24 July 1917 by F2B Felixstowe flying boat. Standard practice was to fly along the U boat and drop 2 250lb bombs astride it, hoping to cause leaks and give time for a destroyer to collect the submariners and sink it. On this occasion, by fluke, one bomb went through the conning tower and blew the base out of UC1. MFG Mill was awarded the DFC for this but he refused to wear it because of the total loss of life
