THREE:The regiment moved off at the head of the brigade, and after a march of a mile or so came out upon a hill from which they could see one of our batteries having an unequal fight with several of the rebel batteries in a fort far to its front. Our cannoneers were standing up bravely to their work, but the rebel shells were bursting about them in a wild storm of crashing, deafening explosions, and hurtling, shrieking masses of iron. The sharp crack of their own rifles was at times drowned by the ear-splitting din of the bursting shells.FOR the next few days there was a puzzling maze of movements, which must have completely mystified the rebel Generalsas was intendedfor it certainly passed the comprehension of our own keen-eyed and shrewdly-guessing rank-and-file and lower oflficers.
