The Colonel was with his Regiment at Fredericksburg, in December 1862, though "not much exposed". That winter, Colonel Cobb being elected to Congress, he resigned his position, and Lieutenant Colonel T. S. Allen, of the Second Wisconsin Infantry, was appointed Colonel of the Fifth.
At the President's new call for troops of July 1864, Cobb helped raise and was appointed Colonel of the 43rd Wisconsin Infantry. In October 1864 they were at Nashville, TN. After that time, Cobb was largely on detached duty as the commander of the Supply post at Johnsonville, TN. He mustered out with the Regiment on 25 June 1865.

Cobb served as a Republican representative from Wisconsin in the United States Congress from 1863 to 1871.
He moved to Lincoln, Nebraska, and became Mayor 1873. He was a justice of the Nebraska Supreme Court from 1878 until 1892; Chief Justice for four of those years.
