Tensions grew between Mexican troops and Texas settlers in the 1830s. In 1831, Colonel Juan Bradburn arrested several settlers in Anahuac, including William Travis, angering Texans. Settlers demanded the prisoners' release, but Bradburn refused. John Austin organized settlers and marched on Anahuac with a cannon, though they withdrew when Bradburn agreed to release prisoners. This led to the Turtle Bayou Resolutions where settlers declared they were not in rebellion against Mexico but defending their rights. Conflict continued until Colonel Piedras removed Bradburn from his post and released the prisoners.
