By about 10.30 on 18 April, Cuban troops and militia, supported by tanks, took Playa Larga after Brigade forces had fled towards Girón in the early hours. During the day, Brigade forces retreated to San Blas along the two roads from Covadonga and Yaguaramas. By then, both Fidel Castro and José Ramón Fernández had re-located to that battlefront area.
At about 17.00 on 18 April, FAL B-26s attacked a Cuban column of 12 civilian buses leading trucks carrying tanks and other armour, moving southeast between Playa Larga and Punta Perdiz. The vehicles, loaded with civilians, militia, police and soldiers, were attacked with bombs, napalm and rockets, suffering heavy casualties. The six B-26s were piloted by two CIA contract pilots plus four pilots and six navigators from Brigade 2506 air force. The column later re-formed and advanced to Punta Perdiz, about 11 km northwest of Giron.
