Horse Artillery Battery No. 19: Six 6-pdr guns and two 7-pdr howitzers

Note: The two Kurmark Landwehr cavalry regiments operatedon a detached basis with the infantry brigades. Some sources attribute the 12th (Saxon) Hussars to the III Corps cavalry, but it apparently was not formed in time to participate in the campaign.

Von Borcke, along with the three battalions of the 8th Regiment, one battalion of the 30th Regiment, two battalions of the 1st Kurmark, and Foot Artillery Battery No. 18, were following the other three Prussian Corps to Waterloo, acting as the army's rear guard.

Except for von Borcke's rearguard, Thielemann's corps was not engaged at Ligny. Wavre was its first battle of the campaign. Some sources attribute a 20th Infantry Regiment, to the 10th Brigade, and six foot batteries (one howitzer) to the 11th and 12th Brigades and Artillery Reserve. However, these units were not formed in time to participate in the campaign.

Strolz's division was the first to arrive at Wavre, followed by most of Chatel's division. The 17th Dragoons (350 men in three squadrons) of Berton's brigade were detached on reconnaissance and would not join the brigade until 19 June. Exelmans' cavaley was only lightly engaged at Ligny, and therefore suffered few casualties prior to arrival at Wavre.
