Hiram Bronson Granbury (March 1, 1831 – November 30, 1864) was a lawyer and county judge in Texas before the American Civil War.

[5] Upon the secession of Texas from the Union, Granbury organized the Waco Guards, a volunteer infantry company, and headed east to Kentucky with them as their first captain.

Granbury was imprisoned at Fort Warren in Boston Harbor but was permitted to visit Baltimore on parole in order to attend to his wife, who was to have an operation.

Granbury and his regiment served in north Mississippi with General Joseph E. Johnston's Army of Tennessee during the Vicksburg Campaign.

At the Battle of Franklin on November 30, 1864, Hood ordered 18 brigades to make numerous hopeless frontal assaults against fortified positions occupied by the Union Army forces under Major General John M. Schofield.

Granbury's brigade charged the center of the Federal breastworks and he was shot and killed, along with Major General Patrick R. Cleburne, just 40 yards outside the Union works.

[1] At the time of Granbury's death, he was serving as the elected Senior Warden of Waco Masonic Lodge #92, the oldest organization still in existence in McLennan County.
