To encourage French participation in the struggle for independence, the US representative in Paris, Silas Deane promised promotion and command positions to any French officer who joined the Continental Army. Although many proved incompetent, one outstanding exception was Gilbert du Motier, Marquis de Lafayette, whom Congress appointed a major General. In addition to his military ability, Lafayette showed considerable political skill in building support for Washington among his officers and within Congress, liaising with French army and naval commanders, and promoting the Patriot cause in France.
