HMS M29 was a Royal Navy M29-class monitor constructed during the First World War, built by Harland & Wolff in Belfast. Launched on 22 May 1915 and completed by June of the same year, the vessel was part of a strategic response to the availability of 6-inch Mk XII guns from the Queen Elizabeth-class battleships, which prompted the development of scaled-down monitors utilizing these weapons. The ship featured a relatively compact and utilitarian design typical of monitors, optimized for shore bombardment and coastal operations. Once commissioned, HMS M29 was deployed to the Mediterranean, where she participated in the Battle of Jaffa in 1917, contributing to the Allied efforts during the Sinai and Palestine Campaign. She remained in the Mediterranean until December 1918, providing naval support in a region of critical strategic importance. In May 1919, M29 extended her service to support British and White Russian forces during the Russian Civil War, operating in the White Sea before returning to England. In September 1923, HMS M29 entered a period of significant modification, being converted into a minelayer equipped to carry 52 mines. This conversion was completed in December 1925, and she was renamed HMS Medusa. During the Second World War, her role shifted again, and in May 1941, she was transformed into a repair and depot ship, serving as the depot for the 10th Submarine Flotilla and renamed HMS Talbot. Subsequently, in February 1944, she was renamed HMS Medway II and served as the depot ship for the 1st Submarine Flotilla. Her naval career concluded in December 1946 when she was sold for scrap. Post-service, the vessel was repurposed as a cargo ship following her acquisition by a Greek shipowner around 1950–1951 and was renamed Gerogeorgakis. She was rebuilt at Perama for cargo use but later became involved in smuggling, which led to her seizure off Cavallo Island in 1971. Ultimately, she was auctioned and dismantled for scrap in Vado Ligure in 1974, ending her diverse maritime career.
