The Joint Committee on the Conduct of the War was a investigating committee created to handle issues surrounding the American Civil War. It was established on December 9, 1861, following the embarrassing Union defeat at the Battle of Ball's Bluff, at the instigation of Senator Zachariah T. Chandler of Michigan, and continued until May 1865. Its purpose was to investigate such matters as illicit trade with the Confederate states, medical treatment of wounded soldiers, military contracts, and the causes of Union battle losses. The Committee was also involved in supporting the war effort through various means, including endorsing emancipation, the use of black soldiers, and the appointment of generals who were known to be aggressive fighters. It was chaired throughout by Senator Benjamin Wade
