On the night of 5 June, the British Type 42 destroyer HMS Cardiff took up station on the "Bluff Cove Gunline" to the east of the islands. Tasked with a dual mission, Cardiff was to provide fire support to the Royal Marines of 3 Commando Brigade, and to interdict any Argentine aircraft attempting to fly into Stanley. The destroyer had performed a similar role four nights previously, when she unsuccessfully attempted to shoot down a re-supply aircraft as it landed, and again as it took off.[7][8]
