Bill Hartland served in the Royal Marines as a bandsman for 23 years. Bill has been a contributor to the The Band of Her Majesty's Royal Marines website for years. He served on HMS Gambia for her 1957 - 1958 commission and in 2003 he created the original HMS Gambia Association website wich was online until 2014. Without his help, this website could never have been created and when we finally met in August 2017, he very kindly gave me these photos:

Uckers, a game similar to Ludo, has been popular in the Royal Navy since at least WWI. The Navy Song website (Internet Archive) discusses the game, its rules and their variants.
