Neither commander yet foresaw Gettysburg as a field of battle. Each had expected to take a strong position and force his adversary to attack. But in the hot summer weather fate was moving the mighty hosts closer and closer. The sky was cloudless, and the summer moon was at its brightest. The wheat was ripe, and the armies marched between partly reaped fields. [Illustration: The Pennsylvania Monument, with bronze figures of distinguished officers and a roster of all Pennsylvanians in battle.] On the 30th, Hill, in the front at Cashtown, sent Pettigrew’s Brigade to Gettysburg for supplies, shoes especially being badly needed. In the meantime, Meade ordered Buford, with two brigades of cavalry at Emmitsburg, to make a reconnaissance to Gettysburg. Buford reported: “_I entered this place today at 11_ A.M. _Found everybody in a terrible state of excitement on account of the enemy’s advance._” On reaching Seminary Ridge, Pettigrew saw the approach of Buford. Not wishing to bring on an engagement, he withdrew to the vicinity of Cashtown. Buford moved through the town and bivouacked for the night west of the Seminary, along McPherson Ridge. He assigned to Gamble’s Brigade the task of watching the Fairfield and Cashtown roads and to Devin the Mummasburg, Middletown (now Biglerville), and Harrisburg roads. Early on the morning of the 1st, he picketed all the roads leading north and northeast. THE FIRST DAY Informed by Pettigrew that Union forces had reached Gettysburg, and anxious to know their strength, Hill sent Heth’s and Pender’s Divisions with Pegram’s battalion of artillery forward on a reconnaissance in force. This movement, made at 5.30 A.M. on July 1, precipitated the battle. The advance was soon interrupted by Buford’s skirmishers. On reaching Herr Ridge, which crosses the Cashtown Road at right angles, Hill deployed his line of battle—Heth on both sides of the road with Pender in reserve. Pegram posted his artillery on Herr Ridge, and at 8 o’clock fired his first shot. Buford’s artillery, under Calef, posted on the opposite ridge, fired in reply. The battle was on, and the gravity of the situation was clear to Buford, who at 10.10 A.M. sent this message to Meade: “_The enemy’s force are advancing on me at this point and driving my pickets and skirmishers very rapidly. There is a large force at Heidlersburg that is driving my pickets at that point from that direction. I am sure that the whole of A. P. Hill’s force is advancing._” Arrival of Reynolds.
