Answer:
lack of discipline
Step-by-step explanation:
The Texas Revolution (1835-1836) was a military conflict fought between Texan colonists and the Mexican government. The Texans rebelled against then Mexican president Antonio Lopez de Santa Anna, who rejected federalism and sought a much tighter central control over Mexican territory. Texan colonists, most of whom had emigrated from the United States, felt threatened by this move, as they had achieved a great degree of autonomy and self-rule under the previous federal arrangement.
When Mexican troops moved in to assert control over several Texan towns, the colonists openly revolted and formed a Texan army. However, most of those who joined were volunteers who had little to no military training, and thus lack of discipline was a distinguishing feature of the Texan army at first. Stephen Austin, first commander of this army, had to order his men to remember to obey the orders given to them by their officers. Later on, volunteers from the United States flocked across the borders and joined the Texans. Many of them were or had been in the military, and were used to following a chain of command. This greatly improved the effectiveness of the Texan army, which had until then been bested by the Mexican Army due to their superior training. The war would eventually end on April 21, 1836, when Texan forces captured Santa Anna, whom had been leading his troops himself, and forced him to surrender and sign a treaty signalling the independence of Texas.
