Royal Deux-Ponts Regiment

The Royal Deux-Ponts Regiment (Régiment Royal-Deux-Ponts; Infanterieregiment Königlich Zweibrücken) was a Palatinate-Zweibrücken regiment in French service from 1757 to 1791.

History
The Royal Deux-Ponts Regiment was raised by Christian Duke of Deux-Ponts, Count Palatine of Birkenfeld under a treaty made in 1751 between Louis XV and Christian IV of Deux-Ponts, by which the Duke undertook to provide in the event of war a contingent of 1,000 men to France. In 1775 it was commanded by Colonel Christian, Count of Forbach, nephew of the Duke of Deux-Ponts and future Marquis de Deux-Ponts. The Marquis was colonel-commandant from March 10, 1788 until January 1, 1791, when it was absorbed into the French Revolutionary Army as the 99th Infantry Regiment.

American Revolutionary War
The Royal Deux-Ponts Regiment left Brest on April 4, 1780 as part of a contingent of four regiments sent by France under the orders of Rochambeau to provide support to the American Revolution. It distinguished itself at Yorktown in October 1781. The regiment returned to France in July 1783.

Uniform
During the American Revolutionary War, the uniform was sky blue with distinctive yellow facings.
