The alliance had been made over two years before. During that period, an army under the comte de Rochambeau had been sent to assist Washington, but it had yet to do anything of significance and America was expecting French warships. These were needed, Adams wrote, to contain the British armies in the port cities and contend with the powerful British Navy. However, the French Navy had been sent not to the United States but to the West Indies to protect French interests there. France, Adams believed, needed to commit itself more fully to the alliance. Vergennes responded that he would deal only with Franklin, who sent a letter back to Congress critical of Adams.[118] Adams then left France of his own accord.[119]

Ambassador to the Dutch Republic
In mid-1780, Adams traveled to the Dutch Republic. One of the few other existing republics at the time, Adams thought it might be sympathetic to the American cause. Securing a Dutch loan could increase American independence from France and pressure Britain into peace. At first, Adams had no official status, but in July he was formally given permission to negotiate for a loan and took up residence in Amsterdam in August.
