Price ordered Lt. Dyer to set up an artillery battery, consisting of a 6-pounder and the howitzers, 250 yards from the western flank of the church and began firing at 2 PM and continued for two and a half hours before retiring to Don Fernando for the evening. Early on 4 Feb., he placed Capt. Burgwin's 1st Dragoon Regiment, and Major Clarke's light artillery, in the same position he had the battery the evening before, Capt. St. Vrain's and Capt. Slack's mounted men were placed to prevent escape towards the mountains or Don Fernando, and the remaining men were placed 300 yards from the northern wall along with Lt. Dyer's artillery battery. This placed the front and eastern flank of the church in a crossfire.
