Thursday, July 28. — We moved to the front line.
[We had heard for some time that there was a mine being dug in our front, and that it was to be exploded soon. Dates differed, and we could get very little accurate information. At times I began to think that they were merely the usual camp rumors. It afterwards turned out that the mine was dug by Lieutenant Colonel Pleasants of a Pennsylvania regiment which was largely composed of coal-miners; there were four tons of gunpowder inserted in this mine.]
