The Royal Deux-Ponts Regiment (French: Régiment Royal-Deux-Ponts; German: Infanterieregiment Königlich Zweibrücken) was a Palatinate-Zweibrücken regiment in French service from 1757 to 1791.
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.[1]
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.[2] It distinguished itself at Yorktown in October 1781.[3] The regiment returned to France in July 1783.[4]
During the American Revolutionary War, the uniform was sky blue with distinctive yellow facings.[5]
