Quick BriefFort Allen, named for Union Captain John K. Allen of Company H, 78th Illinois Infantry Regiment, was built from late October to early November 1862 to protect the railroad bridge across the Rolling Fork River. The fort gained prominence during Morgan's Christmas Raid in 1862, when three companies of the 9th Kentucky Cavalry arrived near New Haven late on December 29 and attacked the stockade the following morning. Colonel William H. Benneson of the 78th Illinois Infantry refused the Confederate surrender demand, and the fort's defenders repelled the assault without casualties.

History & Significance

Fort Allen was a Union fortification named for Captain John K. Allen of the 78th Illinois Infantry Regiment, who led its construction in the strategic corridor between Louisville and Nashville. The fortification, occupied from 1862 to 1864, protected the railroad bridge across the Rolling Fork River.

The stockade gained military prominence on December 30, 1862, during the Battle of New Haven, when three companies from William C. P. Breckinridge's Ninth Kentucky Cavalry, with a 12-pound mountain howitzer, attacked the Federal garrison. After a 90-minute skirmish, the Confederate force withdrew; the Union suffered no casualties and the howitzer did not damage the fort.

Following the successful defense, the 78th Illinois was transferred south in January 1863 and replaced by the 63rd Indiana Infantry, who in turn were transferred to Camp Nelson in January 1864 and replaced by the 33rd Kentucky Infantry. After the fort was abandoned in April 1864, its military buildings were burned on September 19, 1864, by guerrilla Henry C. Magruder. The New Haven Battlefield Site was added to the National Register of Historic Places on August 8, 2004.
