1862 August 12th

August 12 1862 Tuesday

Gallatin, TN

Cedar Mountain Campaign

Operations at Baton Rouge

Alabama. The destruction of the railroad tunnel near Gallatin, Tennessee, suddenly severed the main line of supply for Major-General Don Carlos Buell’s army at Bridgeport. The Cumberland River was too low for navigation and Buell was forced to consume his depot of rations collected at Stevenson. The long bridge over the Tennessee was now finally repaired at Bridgeport, opening his route towards Chattanooga, Tennessee, but Buell lacked the assurance of supplies he required to make that advance.

Louisiana. Union troops evacuated Baton Rouge. Union Colonel George W Cahill took over the command of Brigadier-General Thomas Williams, who had been killed at Baton Rouge a week earlier. The brigade was transported back to New Orleans, to strengthen the city’s defence.

Missouri. A Union expedition set out from Camp Gamble to search for Confederate guerrillas.

Missouri. Skirmish between Humansville and Stockton.

Missouri. Skirmish at Van Buren.

Missouri. A Union expedition set out from Fort Leavenworth for Independence to intercept the Confederate guerrillas who had captured the town and were now heading for Kansas City.

Gallatin, Tennessee. After making a forced march from Sparta, Confederate Colonel John Hunt Morgan surprised the Union garrison at Gallatin on the vital Louisville & Nashville Railroad. The garrison comprised detachments from the 2nd Indiana Infantry, 4th Kentucky Infantry, 5th Kentucky Infantry, and 1st Tennessee Cavalry. After the Confederates captured the defenders, they burned the railroad depot and destroyed some bridge trestles. Morgan’s men also set fire to a captured Union supply train loaded with hay and pushed it into the 800-foot railroad tunnel seven miles north of the town. The wooden support beams caught fire and burned until the tunnel collapsed, closing the tunnel and the Louisville & Nashville Railroad for several months. Morgan reported Union casualties as 80 killed or wounded and 200 prisoners for the loss of 24 Confederates.

Texas. USS Arthur, Acting Lieutenant John W Kittredge, captured the armed schooner Breaker at Aransas Pass. The Confederate schooner Elma and sloop Hannah were burned at Corpus Christi to prevent their capture by USS Arthur.

Virginia. Hearing that the Union Army of Virginia had concentrated at Culpeper Court House, Confederate Major-General Thomas Jonathan Jackson withdrew from Cedar Mountain across the Rapidan towards a more defensible position nearer to Gordonsville. Union Major-General John Pope scouted to the Rapidan and then withdrew back to Culpeper.
