In a new campaign ad released Monday, Democratic U.S. Senate candidate Doug Jones portrayed himself as a senator who will seek compromise if elected, referencing Civil War history -- and a Confederate colonel from Alabama -- to make his point.

In the ad, titled "Honor," Jones tells the story of on the Little Round Top at the Battle of Gettysburg, where Col. William Oates of Alabama and Col. Joshua Chamberlain of Maine led troops on opposing sides.

"Those times have passed long ago and our country is better for it, but now we fight too often over other matters. It seems as if we're coming apart," Jones says in the ad. "I want to go to Washington and meet the representatives from Maine and those from every other state, not on the battlefield, but to find common ground -- because there's honor in compromise and civility, to pull together as a people, and to get things done for Alabama."

Jones, a former federal prosecutor, is facing ex-Alabama Supreme Court Chief Justice Roy Moore, a Republican, in the Dec. 12 special election to fill Jeff Sessions' seat.
