The Battle of Goose Green (28–29 May 1982) was an engagement of the Falklands War between British and Argentine forces. Goose Green had little strategic value in the British campaign to recapture the Falkland Islands
and early plans for land operations had called for Goose Green to be
isolated and bypassed. However after significant British losses at sea British Joint Headquarters
in Northwood, UK, came under pressure from the government for an early
success and so they ordered the senior commander on the ground, Brigadier Julian Thompson, commanding 3 Commando Brigade, to mount an attack.
