An immediate effect of the change was to give new vigor to efforts at reaching a settlement with Great Britain. The old troubles over her retention of the western posts still continued, and in addition to them came new difficulties arising from war measures. On January 30, 1793, Thomas Pinckney, then American minister to Great Britain, wrote that war was about to begin, "and although our claim to a free intercourse is founded in reason and our national right, yet, as we have no armed neutrality the members whereof this people have to fear, they may stop our vessels bound to French ports with provisions." What was feared soon happened. By the French decree of 1793, the French colonies were opened to American trade and West Indian commerce flourished. This was now afflicted by contraband regulations laid down by Great Britain, under which many American vessels were seized for carrying cargoes to or from French ports. Although Genet's activities and the extent to which they were indulged by the United States did not tend to promote friendly relations with Great Britain, yet it does not appear that the British policy was inspired by resentment. The regulations as defined by instructions issued on June 8, 1793, made liable to detention all vessels carrying "corn, flour, or meal" to French ports, with the proviso that the cargoes might be purchased on behalf of the British government and the ships might then be released with a due allowance for freight, or they might be allowed to dispose of their cargoes in the ports of any country in amity with Great Britain. Vessels attempting to enter a blockaded port were liable to seizure and condemnation, save that the ships of Denmark and Sweden might be seized only if they should persist in trying to enter after once having been turned back. Conciliatory explanations were made by Hammond, the British minister, in notifying our State Department. He pointed out that only corn and flour were contraband, that the regulations did not extend to other provisions, and that they secured "to the proprietors, supposing them neutral, a full indemnification for any loss they may possibly sustain." The special privilege extended to Denmark and Sweden was attributed to treaty requirements and therefore could not be regarded as invidious. In reply Jefferson at home and Pinckney abroad argued in behalf of the United States for the principle that free ships make free goods, but Great Britain would not hearken to a doctrine that struck at the efficacy of her sea power.
