HEADQUARTERS DISTRICT OF WEST TENNESSEE,
Pittsburg, April 6, 1862.
COMMANDING OFFICER ADVANCE FORCES (BUELL'S ARMY), Near Pittsburg:
The attack on my forces has been very spirited from early this morning. The appearance of fresh troops on the field now would have a powerful effect, both by inspiring our men and disheartening the enemy. If you will get upon the field, leaving all your baggage on the east bank of the river, it will be a move to our advantage, and possibly save the day to us. The rebel forces are estimated at over 100,000 men. My headquarters will be in the log building on the top of the hill, where you will be furnished a staff officer to guide you to your place on the field.
