We’ve visited to site at Goliad a couple of times. The fort is beautifully restored as well as the old mission across the river. The mass grave of Col. Fannin and his men is close by. Not far north is the town of Gonzalez with the “Come and take it” cannon in a museum.
This event in Texas history was also the origination for the iconic Texas flag which portrayed a cannon with the words come and take it.
Goliad was a very small town. A fort and mission were central to the town and had a cannon for defense against the Indians. The Texian forces appropriated the cannon before the Mexican army arrived and the flag was in response for a call to surrender the cannon..
