not to speak above breath

Not able to speak aloud.
We arrived on the scene just after dark, — that is, General Walthall's Division of Stewart's Corps; this division was on the extreme right of the corps, and was the first infantry to arrive at Spring Hill that evening. We were halted in a cornfield, ordered to lie down under arms, be ready for action at a moment's notice, and not to speak above breath.
