From Feb. 19th to March 14th, inclusive, they remained encamped at Franklin, and on the 15th entered upon the Red River campaign.

During the latter part of August and early in September, they participated in the numerous movements of the Army of the Shenondoah.

In September their brigade was detached from its division, and so continued until Oct. 26th. Although in this interval the regiment was engaged in arduous and responsible duties, it failed to share the glory of Gen. Sheridan's battles and victories in September and October.

On the 26th of October they rejoined their division at Cedar Creek, Va., thence on the 9th of November moved to a position between Kearnstown and Newton, and on the 30th of December went into camp at Stevenson's Depot, four miles north of Winchester.

The consolidation was completed in the month of January, under the immediate orders of Gen. Sheridan, the 30th being formed in seven companies, and retaining the field and staff officers without change. The men of the 13th Me., were organized into a battalionm of three companies, commanded by officers of their own regiment. The two battalions were then united, and the consolidation effected by the muster out of five commissioned officers of the 30th and a few non commissioned of both regiments. The companies of the 13th were lettered B, H and K in the new organization.
