One year after the Battle of Mariel, there was a new attempt at reconquest by Spain, from Cuba, confirming the suspicions of the Mexican authorities. Spain appointed Gen. Isidro Barradas, who left the port with 3,586 soldiers with the name "Spearhead Division" and on July 5, went to Mexico. The fleet consisted of a flagship, called the Sovereign, two frigates, two gunships and 15 transport ships, each commanded by Admiral Laborde.
