The negotiations angered Adams, who asked Congress to support defense measures. Congress was skeptical of Adams and demanded that he publish the correspondence that he had received from the American diplomats. Adams complied and Congress was angered, viewing the French as insulting America. A two-year undeclared war followed. French ships harassed and captured American vessels and tried to hinder American trade with Britain. The United States engaged in a military buildup, with George Washington brought out of retirement to serve again as Commander-in-Chief.
