The answer to the question: What is the name of the person rumored to be accompanied by $50,000, which the Texians in Matagorda planned to steal? is inside the article: After learning that Texian troops had attacked Castañeda at Gonzales, Cos made haste for Béxar. Unaware of his departure, on October 6, Texians in Matagorda marched on Presidio La Bahía in Goliad to kidnap him and steal the $50,000 that was rumored to accompany him. On October 10, approximately 125 volunteers, including 30 Tejanos, stormed the presidio.  The Mexican garrison surrendered after a thirty-minute battle. One or two Texians were wounded and three Mexican soldiers were killed with seven more wounded.The Texians established themselves in the presidio, under the command of Captain Philip Dimmitt, who immediately sent all the local Tejano volunteers to join Austin on the march to Béxar. At the end of the month, Dimmitt sent a group of men under Ira Westover to engage the Mexican garrison at Fort Lipantitlán, near San Patricio.  Late on November 3, the Texians took the undermanned fort without firing a shot.  After dismantling the fort, they prepared to return to Goliad.  The remainder of the Mexican garrison, which had been out on patrol, approached. The Mexican troops were accompanied by 15–20 loyal centralists from San Patricio, including all members of the ayuntamiento.  After a thirty-minute skirmish, the Mexican soldiers and Texian centralists retreated. With their departure, the Texian army controlled the Gulf Coast, forcing Mexican commanders to send all communication with the Mexican interior overland. The slower land journey left Cos unable to quickly request or receive reinforcements or supplies.On their return to Goliad, Westover's group encountered Governor Viesca.  After being freed by sympathetic soldiers, Viesca had immediately traveled to Texas to recreate the state government.  Dimmitt welcomed Viesca but refused to recognize his authority as governor.  This caused an uproar in the garrison, as many supported the governor.  Dimmitt declared martial law and soon alienated most of the local residents.  Over the next few months, the area between Goliad and Refugio descended into civil..., can you guess it ?
