Toward the close I had one brigade (Walcutt's) armed with breech-loading "Spencer's;" the cavalry generally had breach-loading carbines, "Spencer's" and "Sharp's," both of which were good arms.
The only change that breech-loading arms will probably make in the art and practice of war will be to increase the amount of ammunition to be expended, and necessarily to be carried along; to still further "thin out" the lines of attack, and to reduce battles to short, quick, decisive conflicts.

It does not in the least affect the grand strategy, or the necessity for perfect organization, drill, and discipline.

The companies and battalions will be more dispersed, and the men will be less under the immediate eye of their officers, and therefore a higher order of intelligence and courage on the part of the individual soldier will be an element of strength.
When a regiment is deployed as skirmishers, and crosses an open field or woods, under heavy fire, if each man runs forward from tree to tree, or stump to stump, and yet preserves a good general alignment, it gives great confidence to the men themselves, for they always keep their eyes well to the right and left, and watch their comrades; but when some few hold back, stick too close or too long to a comfortable log, it often stops the line and defeats the whole object.

Therefore, the more we improve the fire-arm the more will be the necessity for good organization, good discipline and intelligence on the part of the individual soldier and officer.
There is, of course, such a thing as individual courage, which has a value in war, but familiarity with danger, experience in war and its common attendants, and personal habit, are equally valuable traits, and these are the qualities with which we usually have to deal in war.

All men naturally shrink from pain and danger, and only incur their risk from some higher motive, or from habit; so that I would define true courage to be a perfect sensibility of the measure of danger, and a mental willingness to incur it, rather than that insensibility to danger of which I have heard far more than I have seen.
