At the same time with news of the Battle of Leipzig came letters from home which informed Gallatin that his nomination as envoy had been rejected by the Senate. This was the last straw. To remain inactive as an envoy was bad enough; to stay on unaccredited seemed impossible. He determined to take advantage of a hint dropped by his friend Baring that the British Ministry, while declining mediation, was not unwilling to treat directly with the American commissioners. He would go to London in an unofficial capacity and smooth the way to negotiations. But Adams and Bayard demurred and persuaded him to defer his departure. A month later came assurances that Lord Castlereagh had offered to negotiate with the Americans either at London or at Gothenburg.
Late in January, 1814, Gallatin and Bayard set off for Amsterdam: the one to bide his chance to visit London, the other to await further instructions. There they learned that in response to Castlereagh's overtures, the President had appointed a new commission, on which Gallatin's name did not appear. Notwithstanding this disappointment, Gallatin secured the desired permission to visit London through the friendly offices of Alexander Baring. Hardly had the Americans established themselves in London when word came that the two new commissioners, Henry Clay and Jonathan Russell, had landed at Gothenburg bearing a commission for Gallatin. It seems that Gallatin was believed to be on his way home and had therefore been left off the commission; on learning of his whereabouts, the President had immediately added his name. So it happened that Gallatin stood last on the list when every consideration dictated his choice as head of the commission. The incident illustrates the difficulties that beset communication one hundred years ago. Diplomacy was a game of chance in which wind and waves often turned the score. Here were five American envoys duly accredited, one keeping his stern vigil in Russia, two on the coast of Sweden, and two in hostile London. Where would they meet? With whom were they to negotiate?
After vexatious delays Ghent was fixed upon as the place where peace negotiations should begin, and there the Americans rendezvoused during the first week in July. Further delay followed, for in spite of the assurances of Lord Castlereagh the British representatives did not make their appearance for a month. Meantime the American commissioners made themselves at home among the hospitable Flemish townspeople, with whom they became prime favorites. In the concert halls they were always greeted with enthusiasm. The musicians soon discovered that British tunes were not in favor and endeavored to learn some American airs. Had the Americans no national airs of their own, they asked. "Oh, yes!" they were assured. "There was Hail Columbia." Would not one of the gentlemen be good enough to play or sing it? An embarrassing request, for musical talent was not conspicuous in the delegation; but Peter, Gallatin's black servant, rose to the occasion. He whistled the air; and then one of the attaches scraped out the melody on a fiddle, so that the quick-witted orchestra speedily composed l'air national des Americains a grand orchestre, and thereafter always played it as a counterbalance to God save the King.
