General Tyler was there in person, giving directions, and soon after he ordered us all back to our camp in Centreville. This reconnoissance had developed a strong force, and had been made without the orders of General McDowell; however, it satisfied us that the enemy was in force on the other side of Bull Run, and had no intention to leave without a serious battle. We lay in camp at Centreville all of the 19th and 20th, and during that night began the movement which resulted in the battle of Bull Run, on July 21st.
