Хуан Мануэль
Reinforcements arrived at the Christian camp from the various councils of Castile, including the knights Juan Núñez III de Lara and Juan Manuel, Prince of Villena. The fresh troops replaced the soldiers who had been injured or were weakened by hunger. Starting in February 1343, the besiegers began to extend the encircling line to block the sea approaches to the city and thus prevent the arrival of food from Gibraltar. The aim was to block the sea approach to Algeciras with logs connected by chains. The boom eventually extended from the Rodeo point to the south of the city to the Isla Verde, and from there to the Playa de Los Ladrillos to the north. However, in late March 1343 a storm broke up the boom and the logs were washed on shore, providing a useful supply of wood to the besieged.
