The Yuttanavi Memorial Monument tells of the gallantry of The Royal Thai Navy during an attack of French warships during WW2. The Battle of Ko Chang took place on 17 January 1941 during the Franco-Thai War in which a flotilla of French warships attacked a smaller force of Thai vessels, including a coastal defense ship. The battle resulted in a tactical victory by the French Navy over the Royal Thai Navy although the strategic result is disputed. Although all three Thai warships ended up on the bottom, the French light cruiser Lamotte-Picquet, built in 1923 was damaged and the flotilla had to retire.
