Between 10 and 13 March, Pakistan International Airlines cancelled all their international routes to urgently fly "government passengers" to Dacca. These "government passengers" were almost all Pakistani soldiers in civilian dress. MV "Swat", a ship of the Pakistan Navy carrying ammunition and soldiers, was harboured in Chittagong Port, but the Bengali workers and sailors at the port refused to unload the ship. A unit of East Pakistan Rifles refused to obey commands to fire on the Bengali demonstrators, beginning a mutiny among the Bengali soldiers.
