Captain Keith Paul Mills, DSC (born June 1959) is a retired British Royal Marines officer who commanded the defence of South Georgia against the 1982 Argentine invasion.
Early on 3 April 1982, Mills received a radio message from HMS Endurance relaying instructions from London that he should make only a token resistance to any Argentine violation of British territory.
[2] During the two-hour Battle of Grytviken on 3 April 1982, Lieutenant Mills' detachment of 22 Royal Marines inflicted damage on the Argentine corvette ARA Guerrico, hitting her with an 84mm anti-tank rocket and many rounds of small arms fire, and shot down a Puma helicopter, killing two Argentine Marines and one sailor, while sustaining one wounded on the British side.
[3][4] Lieutenant Mills and his Marines were treated as heroes in Britain, and he was awarded a Distinguished Service Cross for the defence of South Georgia.
[9][10] His contribution as British commander at the Battle of Grytviken is commemorated in Mills Peak which is named in his honour.
