Keith Mills (Royal Marines officer)

Lieutenant Keith Mills DSC is the 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. He allegedly replied "sod that, I'll make their eyes water", a remark that became famous.

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. The losses suffered at Grytviken prevented Argentina from occupying the rest of the island, with 15 Britons remaining outside Argentine control on several locations from Bird Island and Schlieper Bay in the northwest to St. Andrews Bay to the southeast.

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.
