ordering that: "If any one attempts to haul down the American flag, shoot him on the spot." Although the telegram was intercepted by
Confederates, and was never delivered to the Treasury agents, the text found its way to the press, and Dix became one of the first heroes of the North during the Civil War. The saying is found on many
Civil War tokens minted during the war, although the wording is slightly modified.

On July 22, 1862, Dix and Confederate Major General
Daniel Harvey Hill concluded an agreement for the general exchange of prisoners between the Union and Confederate armies. This agreement became known as the
Dix-Hill Cartel. It established a scale of equivalents, where an officer would be exchanged for a fixed number of enlisted men, and also allowed for the parole of prisoners, who would undertake not to serve in a military capacity until officially exchanged. (The cartel worked well for a few months, but broke down when Confederates insisted on treating black prisoners as
fugitive slaves and returning them to their previous owners.)

Salmon P. Chase for General John A. Dix. The motive of Chase appeared to be for political influence and not for financial gain.
Dix was considered too old for field command. Some believe that his most distinguished contribution to the war was the suppression of the
New York City draft riots in July 1863, although the rioting had already subsided by the time he replaced General
John E. Wool. He was also active in the
defense of Suffolk, which was part of his department. He served as the temporary chairman of the
1866 National Union Convention.
