The "Come and Take It" cannonball refers to the cannon used by the Texian rebels during the Battle of Gonzales in 1835, which was a part of the Texas Revolution. The cannonball that became associated with the "Come and Take It" slogan was fired from a small cannon.
The cannonball itself was typically about 3 to 4 inches (7.6 to 10 cm) in diameter, which was common for the type of small artillery piece used at the time. The cannon was a six-pounder, and the projectiles fired from it weighed around six pounds (about 2.7 kg).
The "Come and Take It" flag, with its famous slogan and the image of the cannon, became a symbol of defiance and resistance.
