His first assignment, after enrolment, was to be stationed at the Royal Navy Air Station at Eastchurch on the Isle of Sheppey where he was a Stoker 1st Class until the 28th October 1914.
After initial training his first ship was the ‘C’ class destroyer the HMS Recruit which was part of the ‘Nore Local Defence Flotilla’ whose duties included anti-submarine and counter mining patrols in the Thames Estuary.
On the 1st May, whilst patrolling with its sister ship, the HMS Brazen, off the Thames Estuary the Recruit was attacked by the German submarine UB-6 captained by Erich Haecker. She was struck by a single torpedo which broke the Recruit in two and it sank almost immediately with the loss of 39 men, 4 officers: 22 crewmen were rescued. She was one of 17 ships to be sunk by the German UB-6.
George Robert Lamkin was one of the crewmen who lost their lives on that day. His body was never recovered and he is remembered on the Chatham Naval Memorial.
