The men of the 48th Pennsylvania are coal miners, and they have dug a mine beneath the enemy’s defenses around Petersburg. I have little faith that it will accomplish much, but if we can fill it with powder and detonate it, we may be able to break the stalemate. I wrote Gen. Meade,
HEADQUARTERS ARMIES OF THE UNITED STATES,
City Point, Va., July 25, 1864.
Major General GEORGE G. MEADE:
You may direct the loading of the mine in front of the Ninth Corps. I would set no time when it should be exploded, but leave it subject to orders. The expedition ordered may cause such a weakening of the enemy at Petersburg as to make an attack there possible, in which case you would want to spring Burnside’s mine. It cannot be kept a great while after the powder is put in. I would say, therefore, if it is not found necessary to blow it up earlier, I would have it off during the afternoon of Wednesday.
