Limahong retreated to
Pangasinan, where he decided to settle, building a fort and counter fort. The fort walls were made from palm logs, while the counter fort used palm planks. Limahong was able to seize several nearby village chiefs, forcing the villagers to provide him with provisions. Juan de Salcedo was made master of camp, a fort was built to better protect Manila, and plans were made to send an expedition against Limahon. Salcedo's expedition of 256 men, with 2500 native allies, set sail on 23 March 1575, with 59 vessels commanded by Captains Chacon, Chaves, Ribera, and Ramirez. They arrived at Pangasinan on
Holy Wednesday, 30 March. Salcedo set about blockading the
Agno River, landing men and artillery. He then sent Captains Pedro de Chaves and Chacon up the river in nine small boats, with eight men each, to capture any Chinese boats. Salcedo also sent Capt. Ribera and 28 men to assault Limahon's fort from the land side. At the same time, 35 Chinese vessels were departing in a search for provisions, and when Limahon's men caught sight of the Spanish, they panicked, and fled to their fort. Thus, the Chinese abandoned their vessels to the Spanish, who promptly burned them. In the meantime, Capt. Ribera succeeded in gaining entrance to Limahon's fort capturing 100 women and children. Yet, the approach of night forced the Spanish to retreat. The Chinese were able to regroup and a long four-month siege ensued. Limahon made use of the time to build 30 ships within his fort. On 4 August, Limahon set sail and made good his escape. Shortly before the escape of Limahong, a Chinese fleet under Wang Wanggao (; known in Spanish sources as Omocon), arrived to spy on Limahon. Once Wang saw that Limahon was besieged, Wang departed for China with the news, taking along some of the Spanish, including some
friars. ==Later activities==
