On the day following this useless cannonade, each regiment of the corps had dress-parade at six o'clock P. M. Orders from General Stoneman were read by the adjutants of their respective regiments, informing them that the entire cavalry force would move at an early hour next day. A portion of the evening was spent in preparation. However, when in the bivouac, as we have been for some time, it takes but a few moments to prepare for a move. All surplus baggage, which naturally accumulates during winter-quarters, has been disposed of, either by sending it home, or to some quartermaster depot, established for the purpose, as at Alexandria, or by destruction; and each man carries only what little articles he can stow away in his saddle-bags and roll up in his blanket. His inventory might run as follows: A shirt, a pair of socks (and often he has only those he wears), a housewife or needle-book, paper and envelopes, a tin cup, and bag which contains his coffee and sugar mixed together. Some men carry a towel and soap. The great effort is to learn to get along with the very least possible. At first the soldier thinks he must have this article of luxury and the other, until he finds that they are positive burdens to himself and horse, and gradually he throws off this weight and that incumbrance, until his entire outfit is reduced to nearly "the little end of nothing, whittled to a point!" Possessed of a coffee-bag and cup and a hard-tack or biscuit, the most essential things, he seldom now borrows much trouble about the rest of men and things. _April 20._--We commenced march at four o'clock this morning on the road to Sulphur Springs. Scarcely had we gone out of our bivouacs before a drenching rain-storm set in, and continued incessantly until we were forced to halt, the mud being really oceanic. The day being quite warm, we experienced but little discomfort from the wet until night. The weather then became cold, and every thing being so wet, it was difficult to make fires; consequently we had a very tedious night. A fellow considered himself fortunate, if, after toiling long through the cold and dark, he could succeed to cook a little coffee. But the soldier will have his coffee, if it be possible, and then he is quite contented with his lot. On the twenty-first, all we could do was to change our position, to get out of the very deep mud, which one night's treading of the horses' feet produced. On the following day in the afternoon the Cavalry Corps moved from Waterloo Bridge to Warrenton Junction. The day was pleasant, though the roads are still in a fearful condition. Our infantry is engaged in repairing the railroad to Rappahannock Station. We are evidently on the eve of some important movements.
