| History | In 1937 HMS Effingham was extensively refitted and re-armed as a light cruiser. Her 7.5-inch guns were replaced by nine 6-inch and her single 4-inch AA guns by twin mountings. Her two funnels were replaced by one, unraked, to give her an appearance markedly similar to that of the later Leander class.
On 18 May 1940 HMS Effingham (Capt. John Montagu Howson, RN) was carrying the 2nd Battalion, South Wales Borderers, as well as other troops, from Ankenes to Bodo. Commanding Officer: |
