The Federal Draft of 1863

By 1863, federal authorities concluded that leaving conscription in the hands of states was clumsy and unworkable, and lacked provisions for adequate enforcement. This realization led to the first comprehensive military draft, mandated, organized and enforced by the federal government. In Bucks County, newly appointed Provost Marshal for the 5th Congressional District, Mahlon Yardley, took on the responsibility for implementing and enforcing conscription. Again, bounties raised and volunteer enlistments encouraged, but in the end, a draft needed to meet quotas. In July 1863, the first federal draft held at the Board of Enrollment offices in Frankford, northeast of Philadelphia. A total of 1,656 Bucks County men selected. Many of these draftees would fail to report or desert. Others rejected due to disability, received exemptions, hired substitutes or paid the commutation fee. Some, however, reported for service and joined regiments in the field. With more calls for troops in 1864 and 1865, federal conscription would continue to the close of the War.  

To the Senate of the United States:

I nominate Mahlon Yardley to be collector internal revenue, 5th district of Pennsylvania, he having been designated during the recess of Senate to perform the duties of that office in place of Joseph Barnsley, suspended.
