When HMS Achilles opened fire on the German ‘pocket battleship’ Admiral Graf Spee on 13 December 1939, it became the first NZ unit to engage the enemy in the Second World War. Seventy years on, the Battle of the River Plate still holds a special place in this country's naval history.
New Zealand was one of the first states to answer the Security Council's call with combat assistance (sixteen would eventually do so). On 29 June, the government offered two frigates, and HMNZS Tutira and Pukaki left Auckland on 3 July.
