and with their whole fquadron and armaments moved to the bottom of the bay. But, by the diligence and indufiry of our people, they found all the artillery of fort Santa Cfuz nailed up. ‘This fort was alío, from its largenefs, called Caftillo Grande, and coameamded all the fhips which anchor in the bay. This, together with that of Boca Chica, St. Jofeph, and two others, lillo, the enemy, enragéd at their difappointment, de- molifhed when they quitted the bay.
