[2] As early as September 1835, Moore had been an advocate of Texas independence and warned against attacks by the Mexican Army to the point that general Martín Perfecto de Cos had ordered that he be arrested.

On September 25, 1835, The Committee of Safety of the town of Gonzales had requested aid from nearby counties in their standoff with Francisco de Castañeda.

After the battle, Moore met with Castañeda where he explained that the Texians were rebelling against the rule of Santa Anna and his repudiation of the 1824 Constitution.

President Sam Houston had ordered Moore to raise and lead 200 men to defend San Antonio from both Comanche and Mexican attacks and raids.

While pursuing Indians who had attacked an outpost on Cummins Creek in August 1842, Moore became so ill with rheumatism that it had been reported that he had died from the disease.

Later that year, Moore also served under the command of Matthew Caldwell in the Battle of Salado Creek, repelling an invasion by Mexican forces.
