Before Franklin reached America, the War of Independence, though not formally declared, had fairly begun. He was appointed a member of the second Continental Congress, and one of a committee of three to confer with General Washington respecting the support and regulation of the Continental Army. This latter office necessitated his spending some time in the camp. On October 3, 1775, he wrote to Priestley:—
Tell our dear good friend, Dr. Price, who sometimes has his doubts and despondencies about our firmness, that America is determined and unanimous; a very few Tories and placemen excepted, who will probably soon export themselves. Britain, at the expense of three millions, has killed a hundred and fifty Yankees this campaign, which is £20,000 a head; and at Bunker's Hill she gained a mile of ground, half of which she lost again by our taking the post on Ploughed Hill. During the same time sixty thousand children have been born in America. From these data his mathematical head will easily calculate the time and expense necessary to kill us all and conquer our whole territory.
In 1776 Franklin, then seventy years old, was appointed one of three Commissioners to visit Canada, in order, if possible, to promote a union between it and the States. Finding that only one Canadian in five hundred could read, and that the state of feeling in Canada was fatal to the success of the Commissioners, they returned, and Franklin suggested that the next Commission sent to Canada should consist of schoolmasters. On the 4th of July Franklin took part in the signing of the Declaration of Independence. When the document was about to be signed, Mr. Hancock remarked, "We must be unanimous; there must be no pulling different ways; we must all hang together." Franklin replied, "Yes, we must indeed all hang together, or most assuredly we shall all hang separately."
In the autumn of 1776 Franklin was unanimously chosen a Special Commissioner to the French Court. He took with him his two grandsons, William Temple Franklin and Benjamin Franklin Bache, and leaving Marcus Hook on October 28, crossed the Atlantic in a sloop of sixteen guns. In Paris he met with an enthusiastic reception. M. de Chaumont placed at his disposal his house at Passy, then about a mile from Paris, but now within the city. Here he resided for nine years, being a constant visitor at the French Court, and certainly one of the most conspicuous figures in Paris. He was obliged to serve in many capacities, and was very much burdened with work. Not only were there his duties as Commissioner at the French Court, but he was also made Admiralty Judge and Financial Agent, so that all the coupons for the payment of interest on the money borrowed for the prosecution of the war, as well as all financial negotiations, either with the French Government or contractors, had to pass through his hands. Perhaps the most unpleasant part of his work was his continued applications to the French Court for monetary advances. The French Government, as is well known, warmly espoused the cause of the Americans, and to the utmost of its ability assisted them with money, material, and men. Franklin was worried a good deal by applications from French officers for introductions to General Washington, that they might obtain employment in the American Army. At last he framed a model letter of recommendation, which may be useful to many in this country in the present day. It was as follows:—
"Sir,
The bearer of this, who is going to America, presses me to give him a letter of recommendation, though I know nothing of him, not even his name. This may seem extraordinary, but I assure you it is not uncommon here. Sometimes, indeed, one unknown person brings another equally unknown, to recommend him; and sometimes they recommend one another! As to this gentleman, I must refer you to himself for his character and merits, with which he is certainly better acquainted than I can possibly be. I recommend him, however, to those civilities which every stranger, of whom one knows no harm, has a right to; and I request you will do him all the good offices and show him all the favour that, on further acquaintance, you shall find him to deserve.
I have the honour to be, etc.
Captain Wickes, of the Refusal, having taken about a hundred British seamen prisoners, Franklin and Silas Deane, one of the other Commissioners, wrote to Lord Stormont, the British ambassador, respecting an exchange. Receiving no answer, they wrote again, and ventured to complain of the treatment which the American prisoners were receiving in the English prisons, and in being compelled to fight against their own countrymen. To this communication Lord Stormont replied:—
The king's ambassador receives no applications from rebels, unless they come to implore his Majesty's mercy.
To this the Commissioners rejoined:—
In answer to a letter, which concerns some of the most material interests of humanity, and of the two nations, Great Britain and the United States of America, now at war, we received the enclosed indecent paper, as coming from your Lordship, which we return for your Lordship's more mature consideration.
At first the British Government, regarding the Americans as rebels, did not treat their prisoners as prisoners of war, but threatened to try them for high treason. Their sufferings in the English prisons were very great. Mr. David Hartley did much to relieve them, and Franklin transmitted money for the purpose. When a treaty had been formed between France and the States, and France had engaged in the war, and when fortune began to turn in favour of the united armies, the American prisoners received better treatment from the English Government, and exchanges took place freely. In April, 1778, Mr. Hartley visited Franklin at Passy, apparently for the purpose of preventing, if possible, the offensive and defensive alliance between America and France. Very many attempts were made to produce a rupture between the French Government and the American Commissioners, but Franklin insisted that no treaty of peace could be made between England and America in which France was not included. In 1779 the other Commissioners were recalled, and Franklin was made Minister Plenipotentiary to the Court of France.
