Detailed planning began in early January 1982. It was headed by Vice Admiral Juan José Lombardo (Commander-in-Chief Fleet) and included General Osvald Garcia (commander of the Fifth Army Corps) and Brigadier Sigfrido Plessel, (member of the Air Force Staff). The operation would be an amphibious landing of 3,000 troops "en masse" to minimise bloodshed. The contingent of Royal Marines, British civil service officials and the more anti-Argentine among the Falklanders would be deported and the bulk of the invasion force would return to their bases within 48 hours. A military governor and a gendarmerie of about 500 would be left to keep the Falklanders in line. Anaya's draft planned to replace the entire island population with Argentine settlers, but Lombardo believed that such a step would outrage the international community. Instead the Falklanders should be offered financial compensation if they wished to emigrate.
