The next day, General McAllen received an official letter in which the council of the “free city of Houston” demanded from him to leave the city with his troops. He considered the letter a joke, but when he received a similar letter from the civilian government of Texas the same afternoon, demanding of him to withdraw his troops from the free nation of Texas, he began to understand.
After another three hours, he ordered his troops to surround Houston’s governmental building to arrest those responsible for rebellion. The city’s militia, however, supported the cessation and began their march to support the rebels, and when McAllen’s troops saw a well trained force opposing them, the general saw his own units being chased through the streets toward his HQ. Twelve hours of urban combat later, McAllen had no other choice but to order his troops to retreat from the city. Neither the general nor his demoralized men realized what exactly they had done.
