In the battle of Gettysburg the regiment was not very actively engaged, but was ordered to support a battery, and in doing so the men were forced to be inactive while exposed to the shelling of the enemy's guns. Arthur felt hungry, and gave an instance of his coolness by making a fire against a stone wall and cooking and eating his dinner. His comrades, whom he invited to share it with him, preferred to wait until a quieter season. The following letter, written on the 5th, gives a partial account of the battle.
dear——,—The Baltimore Clipper of the 4th gives a weak account of our successes. The fight of Friday, P. M., the climax of the whole, had not been heard from. I have just been to a part of the field where the Rebel masses were urged upon our intrenchments, and met with a terrific slaughter. I give no newspaper account.

As for our part, we reached here on the 1st, after a very rapid and trying march. We took up our position in front of the cemetery and behind a stone fence. The batteries did all or nearly all the fighting in that quarter, and we were not engaged. The next day we moved to the right centre, and in the afternoon were taken up to a field in front of one of our batteries. A Rebel battery soon opened and played on us and the guns we supported for over an hour. We lay behind the stone fence with the shells bursting all around us. One shell instantly killed two of our company, another lost his arm, a third was severely wounded. Other companies also suffered. Companies I, D, and A were then sent out as skirmishers. Soon after, our battery silenced the Rebels,
