In the morning of the 16th, the First Corps (ZIETEN's) occupied that portion of the position which is circumscribed by the Villages of Bry, St Amand la Haye, St Amand, and Ligny. The four Brigades of this Corps had been very much mixed up together when occupying these Villages during the night, which will account in some measure for the promiscuous manner in which their several Battalions appear to have been distributed during the Battle. The main body of the Corps was drawn up on the Height between Bry and Ligny, and upon which stands the Farm and Windmill of Bussy, the highest point of the whole position. Seven Battalions of the Second Brigade (General PIRCH II.) were formed immediately in rear of this Farm; the 28th Regiment and 2nd Westphalian Landwehr in the First, and the 2nd and 3rd Battalions of the 6th Regiment in the Second, Line; while the 3rd Battalion of the latter Regiment occupied the Farm itself, which was put into a state of defence. Two Battalions of the Fourth Brigade (General Count HENKEL), namely, the 2nd Battalions of the 19th Regiment and of the 4th Westphalian Landwehr, stood on the slope between the Second Brigade and Ligny; while the remaining four Battalions of the Brigade--the 1st and 3rd of the 19th Regiment, and the 1st and 3rd of the 4th Westphalian Landwehr--were charged with the defence of Ligny. The Village of Bry was occupied by the 3rd Battalions of the 12th and 24th Regiments, belonging to the First Brigade (General STEINMETZ); and the 2nd Battalion of the 1st Westphalian Landwehr was posted in rear of the Village in support. The 1st and 3rd Companies of the Silesian Rifles, attached to this Brigade, were distributed about the intersected ground between Bry and St Amand la Haye. The remainder of the First Brigade was posted on the Height in the rear of St Amand, its Right resting on St Amand la Haye; the 1st and 2nd Battalions of the 12th Regiment on the right, and the 1st and 2nd Battalions of the 24th Regiment on the left, forming a First, and the 1st and 3rd Battalions of the 1st Westphalian Landwehr forming a Second, Line. The defence of St Amand was confided to three Battalions of the Third Brigade (General JAGOW)--the 1st and 2nd of the 29th Regiment, and the 2nd Battalion of the 3rd Westphalian Landwehr. The remaining six Battalions of this Brigade were posted in reserve northward of Ligny, and near the Bois du Loup. The 2nd and 4th Companies of the Silesian Rifles were thrown into Ligny. The Reserve Cavalry of ZIETEN's Corps continued in advance, upon the Fleurus high road, watching the movements of the Enemy. * * * * *
