RMS Olympic holds the unofficial award of being the only passenger liner to ram - and sink - a German U-Boat during the First World War. On 12 May 1918, while enroute for France in the English Channel transporting U.S. troops Olympic sighted a surfaced U-boat 1,600 ft ahead. Olympic's gunners opened fire, and the ship turned to ram the submarine. U-103 immediately crash dived to 98 ft and turned to a parallel course readying its stern torpedoes. Olympic struck the submarine just aft of her conning tower with her port propeller slicing through the pressure hull. The crew of U-103 blew her ballast tanks, and abandoned the submarine. Olympic did not stop to pick up survivors, but continued on to Cherbourg. An escort, USS Davis had sighted a distress flare and picked up 31 survivors from U-103. Olympic returned to Southampton with at least two hull plates dented and her prow twisted to one side, but not breached.
For his service, Ollympic's Captain Hayes was awarded the DSO. Some American soldiers on board paid for a plaque to be placed in one of Olympic's lounges to commemorate the event, it read:
"This tablet presented by the 59th Regiment United States Infantry commemorates the sinking of the German submarine U103 by Olympic on May 12th 1918 in latitude 49 degrees 16 minutes north longitude 4 degrees 51 minutes west on the voyage from New York to Southampton with American troops."
During the war, Olympic carried 201,000 troops and other personnel, burning 347,000 tons of coal and travelling about 184,000 miles. Olympic's war service earned her the nickname Old Reliable. Her captain was knighted in 1919 for "valuable services in connection with the transport of troops".
Dazzle is a type of ship camouflage that was used extensively in World War I. The unusual paint job on Ollympic is refereed to as Dazzle. Unlike other forms of camouflage, the intention of dazzle was not to conceal but to make it difficult to estimate a target's range, speed, and heading. Norman Wilkinson, the marine artist who invented it, explained in 1919 that he had intended dazzle primarily to mislead the enemy about a ship's course and so cause them to take up a poor firing position. If you think painting kilts is difficult try this!

Scan of wreak of U-103 |
The remains of U-103 lie at a depth of 300 ft in the English Channel, about midway between England and France. Its deep location makes it inaccessible to divers but the wreck was surveyed and identified by a remotely operated underwater vehicle in 2012.
