"Boys, let me sight this gun for you." Running his eye along the sights and giving the elevating screw a turn, he said: "Now, let her go!" In an instant the death-dealing missile was speeding on its way, entered the enclosure and exploded amid the startled gunners of the enemy. "There, boys, that's the way to shoot. Don't waste your powder!" said the colonel, as he turned and walked away, an expression of satisfaction wreathing his florid face. By the 3d of May all things were in readiness to open our batteries of big guns on the Confederate fortifications and all were in excited expectation of the bombardment and possible storming of the enemy's works on the following day, but the morning light of the 4th revealed the enemy's strong works abandoned and empty. In the night, Johnson, who had superseded Magruder in command, like the Arab had "folded his tent and silently stolen away." The 105th Pennsylvania were the first to enter the abandoned works. The news of the evacuation of the works and retreat of the Confederates spread rapidly from regiment to regiment, and our bloodless victory, but not without the loss of many a brave boy, was celebrated with wild shouts and cheers. The cavalry followed closely on the heels of the retreating enemy, but the infantry did not take up the line of march until later in the day; Fighting Joe Hooker's division following first, with Kearny close in his rear. As we marched through the Confederate works, stakes planted upright in the ground with red danger signals attached gave warning that near them were planted torpedoes, placed there for the injury of the unwary by the enemy. A story was told at the time that the planting of these torpedoes was revealed to Lieut. R. P. Crawford, of Company E, of the 57th, then serving as aid on General Jameson's staff, by a Confederate deserter. That the 105th Pennsylvania, being about to enter the abandoned works, this Confederate stepped out from the shelter of a building, and, throwing up his hands as an indication that he desired to surrender, came forward and revealed to Lieutenant Crawford, who chanced to be present, the secret danger that threatened them if they attempted to enter the works without caution. Thus forewarned of their danger, a squad of prisoners, under compulsion, were made to search out, and locate these concealed missiles, thereby preventing possible loss of life and woundings.
