Taking advantage of the British pause, the Argentine Junta then ordered the ARA "Bahía Paraíso" to land a party of Buzos Tacticos (special forces) led by Lieutenant Alfredo Astiz ("the blond angel of death"). Rather than force a confrontation, the Royal Marines were ordered to set up an observation post to monitor the situation at Leith. The full party of Royal Marines was not landed until 31 March when it became apparent that Argentine forces intended to seize the Falkland Islands. The Grytviken Base was actually assaulted the day after the Falklands, since bad weather prevented an attack on the same day.
