Volume 5 covers only three months of the final part of Jefferson's governorship. From late February to late May 1781, Jefferson continued to deal with the complex problems of supporting Greene's army in the south, to cope with the threat from Indians in the southwest, to support George Rogers Clarks's intended campaign against Detroit, to aid Lafayette and Steuben in a final attempt to capture Benedict Arnold at Portsmouth, and to lay the foundations for the triumph of American arms at Yorktown.
