Cos arrived in Texas by sea at the port of Copano on September 20, 1835 with 500 soldiers and proceeded to the town of Goliad on October 1, where he ordered the arrest of rebel leaders and garrisoned his men inside the nearby Presidio La Bahía. Even before his arrival, a group of Texians had plotted to kidnap Cos at either Copano or Goliad, but a rebellion committee rejected the idea. The Texas Revolution began in earnest with the Battle of Gonzales on October 2, and upon learning of the Texian victory, Cos hurried to San Antonio de Béxar, leaving with the bulk of his men on October 5. Texians assaulted the Presidio La Bahía at the Battle of Goliad on October 10, only to learn that Cos had already left.
