On 20 September 1911, the "Olympic" was involved in a collision with the Royal Navy Warship in the Brambles Channel in Southampton Water while under the command of a harbor pilot. The two ships were close enough to each other that "Olympic" motion drew the "Hawke" into her aft starboard side, causing extensive damage to the liner – both above and below her waterline ("HMS Hawke" was fitted with a reinforced 'ram' below the waterline, purposely designed to cause maximum damage to enemy ships). An Admiralty inquiry assigned blame to the "Olympic", despite numerous eyewitness accounts to the contrary.
