While Jefferson was laboring over the Declaration of Independence, Adams worked on the Model Treaty. The Model Treaty authorized a commercial agreement with France but contained no provisions for formal recognition or military assistance. There were provisions for what constituted French territory. The treaty adhered to the provision that "free ships make free goods," allowing neutral nations to trade reciprocally while exempting an agreed-upon list of contraband. By late 1777, America's finances were in tatters, and that September a British army had defeated General Washington and captured Philadelphia. More Americans came to determine that mere commercial ties between the U.S. and France would not be enough, and that military assistance would be needed to end the war. The defeat of the British at Saratoga was expected to help induce France to agree to an alliance.[103]
In November 1777, Adams learned that he was to be named commissioner to France, replacing Silas Deane and joining Franklin and Arthur Lee in Paris to negotiate an alliance with the hesitant French. James Lovell invoked Adams's "inflexible integrity" and the need to have a youthful man who could counterbalance Franklin's advanced age. On November 27, Adams accepted, wasting no time.
