THE BATTLE OF ANTIETAM ( SHARPSBURG) 17th September 1862
Timeline 9.30AM.
The Union Twelfth Corps is now commanded by Brigadier General Alpheus S Williams following the demise of Mansfield. He is advancing towards the Dunkard church with the remnants of the First and Second Divisions.
His advance is now supported by the Union Second Division commanded by Major John Sedgwick, currently negotiating, with difficulty, the burning Mumma farm complex.
The Union advance at the Mumma farm is being made through a hail of Confederate canister fire from John Bell Hood’s divisional artillery.
Contemporaneously, Hood’s Division is being subjected to heavy Union shelling as it retreats, along with the remains of Jackson’s command into the relative safety of the West wood.
Meanwhile, detecting Union activity on the heights over the Rhorbach bridge Longstreet has ordered another Brigade to support Brigadier General R.A. Tombs troops. This Brigade is passing the John Otto house prior to deploying in support.
Whilst General Jackson has reinforcements of six fresh brigades from Longstreet in reserve, his original command has been severely depleted. The Confederate centre awaits the new onslaught with trepidation.
