Armoured Cruisers

HMS Endymion like most of the Edgar class started the war as part of the 10th Cruiser Squadron which was tasked with enforcing the northern blockade on Germany.  Unfortunately these old cruisers were not well suited to the task as they had insufficient sea-keeping and endurance and in 1915 they were replaced by Armed Merchant Cruisers. The class then took on many secondary roles, several serving in the Dardanelles.

HMS Shannon painted in dazzle camouflage.  The Royal Navy tried several schemes to camouflage ships including false bow waves, various colours and animal like stripes or spots.  Dazzle schemes, introduced in 1917, worked on the principle that the strongly contrasting irregular patterns used made it hard for an attacking submarine to accurately gauge a ships course and speed, thus making targeting hard.
