In 1863 at Jackson, the surviving crew of the 2nd Vermont Battery probably reached Spring Branch by turning onto Erin Street, and as the battery crossed the stream a round passed through the leg of its commander, Lieutenant Dyer, killing his mount. The battery then retreated to a dead end in front of the State Insane Asylum, a domed clock tower building completed circa 1855, after another wrong turn, and there the gun and its crew were captured by Confederates. Meanwhile the main body of Federal troops retreated from Jackson along the Jackson-Clinton Road toward Port Hudson, harassed by Colonel Logan's Confederates for most of the twelve mile withdrawal until the Federal garrison was reached near midnight, while some Federals separated during the initial Confederate attack arrived over the next several days. Casualties were small compared with other Civil War engagements: the Confederate force suffered ten casualties, with 5 killed, 1 wounded, and 4 captured, while Hanham's Union force suffered 45 casualties, with 4 killed, 2 wounded, 40 captured including one wounded, and the loss of the 2nd Vermont's two-gun battery. At the time of the battle, the white house at the bottom of the hill at East College and Erin Streets was the residence of notary and portrait painter Thomas F. Noone, a native of Virginia, and diarist Celine Fremeaux Garcia is believed to have lived in a nearby building that no longer stands.
