View source for Twelfth Cruiser Squadron (Royal Navy)

The '''Twelfth Cruiser Squadron''', also known as '''Cruiser Force G''' from 1914 to 1915, was a cruiser formation of the [[Royal Navy]].  

When World War One broke out '''Cruiser Force G''' was responsible for patrolling the Western Approaches to the English Channel in conjunction with the [[Deuxième Escadre Légère]] and in particular making sure that ships entering and leaving were subject to stop and search.  [[Rosslyn Erskine Wemyss, First Baron Wester Wemyss|Admiral Wemyss]] was specially selected for the command for his 'knowledge of and sympathy with' the French. Although no formal co-operation arrangement had been agreed prior to the outbreak of hostilities, it was quickly agreed that '''Cruiser Force G''' would operate under the overall command of the French [[Second Armoured Cruiser Division (French Navy)|Second Armoured Cruiser Division]], which would share the patrol, and that the two units would cover their respective sides of the Channel.{{UKNSMonoX|pp. 54-55}}
