Jay was instructed by Alexander Hamilton to seek compensation for the seizure of American ships and to clarify the rules governing the British seizure of neutral ships. He was also to insist that the British relinquish their posts in the Northwest. In return, the U.S. would take responsibility for pre-Revolution debts owed to British merchants and subjects. He also asked Jay, if possible, to seek limited access for American ships to the British West Indies. Jay and the British Foreign Secretary, Lord Grenville, began negotiations on July 30, 1794. The treaty that emerged several weeks later, commonly known as the Jay Treaty, was, in Jay's words "equal and fair." Both sides achieved many objectives; several issues were sent to arbitration. For the British, America remained neutral and economically grew closer to Britain. The Americans also guaranteed favorable treatment to British imports. In return, the British agreed to evacuate the western forts, which they had been supposed to do by 1783. They also agreed to open their West Indies ports to smaller American ships, allow small vessels to trade with the French West Indies, and set up a commission that would adjudicate American claims against Britain for seized ships, and British claims against Americans for debts incurred before 1775. As the treaty contained neither concessions on impressment nor a statement of rights for American sailors, another commission was later established to settle both those and boundary issues.
