After the invaders disembarked practically all fighting was land based with many skirmishes, field artillery and mortar fire exchanges between the San Gerónimo and San Antonio Bridge fortress and British emplacements in Condado to the East and El Olimpo hill in Miramar to the South. The British tried to take the San Antonio, a key passage to the San Juan islet, and repeatedly bombarded the nearby San Gerónimo to the tune of nearly one thousand shells and almost demolishing it. At the Martín Peña Bridge, they were met by the likes of Sergeants José and Francisco Díaz and Colonel Rafael Conti who together with Lieutenant Lucas de Fuentes attacked the enemy with two cannons.
