One the challenges for American Revolution historians is that not all sources are written in English. This is particularly true for those associated with the French involvement in the Revolution. For example, the Treaty of Aranjuez (1779) confirmed the Spanish committment of the Bourbon Family Compact to enter a war with Great Britain on the side of the French. This treaty is found in the Davenport volume listed below but is only available in French.
More American Revolutionary events took place in Paris, France than most people imagine. A historically minded Boy Scout completed an Eagle Project which presents a comprehensive walking tour of the American Revolutionary War sites in Paris. The guided walk starts at the house the John Adams resided in during his diplomatic stay, continues to twenty-three sites and ends at the memorial to the Lafayette Squadron of World War I.
