Diary of Lieutenant-Colonel John Beatty: August 10, 1861

My tent is on the bank of the Valley river. The water, clear as crystal, as it hurries on over the rocks, keeps up a continuous murmur.

There will be a storm to-night. The sky is very dark, the wind rising, and every few minutes a vivid flash of lightning illuminates the valley, and the thunder rolls off among the mountains with a rumbbling, echoing noise, like that which the gods might make in putting a hundred trains of celestial artillery in position.
