October 2, 1835.
That’s the day the Mexican military commander in Texas found out that colonists from America didn’t think much of his demand that they surrender a small cannon the Mexican government had given them in 1831 to defend themselves against Indian attack. He’d trotted out 100 dragoons to retrieve said cannon on September 27th, hoping to avoid conflict. (What part of sending 100 soldiers to take back a cannon seemed non-confrontational to him, I wonder?) Anyway, October 2 was the day the Texas militia responded loud and clear.
The “Come and Take It” skirmish was short, but in the end the colonists kept their cannon and the Mexican soldiers were sent skedaddling. More significant than the incident itself was the clear break between independent-minded citizens and a dictatorial government.
