It is beyond the scope of this work to trace the progress of the war, and it is for the military historian to criticise its conduct; but it was patent that the purchase of Hessian troops was a great diplomatic blunder. To invoke the aid of hired mercenaries was to make the breach irrevocable, as well as to set against the country employing them the sympathy of other nations. Frederick the Great said he "should make all the Hessian troops, marching through his dominions to America, pay the usual cattle tax, because though human beings they had been sold as beasts." The case has been well put by Lord Mahon. "If any men were needed, was there any lack of them in England?" he asked, "was it wise to inform foreign states that we deemed ourselves thus dependent on foreign aid. Was it wise to hold forth to America the first example of obtaining assistance from abroad? Above all, if conciliation was the object full as much as conquest, how signal the imprudence thus in the midst of a civil strife, to thrust forward aliens to both parties, in blood, in language, and in manners."[170] Chatham inveighed against "the traffic and barter driven with every pitiful German prince that sells his subjects to the shambles of a foreign country. This mercenary aid on which you rely irritates to an incurable resentment the minds of your enemies. To overrun them with the mercenary sons of rapine and plunder; devoting them and their possessions to the rapacity of hireling cruelty! If I were an American, as I am an Englishman, while there was a foreign troop in my country, I never would lay down my arms, never! never! never!"
Chatham's popularity, affected somewhat by his acceptance of a pension, had been greatly diminished when he went to the House of Lords, but now, when the country was in danger, all eyes were turned on him as the only man who could conceivably extract from the situation peace with honour. "If there be a man who has served this nation with honour to himself and glory to his country," said George Grenville the younger in the House of Commons on February 11, 1778, "if there be a man who has carried the arms of Britain triumphant to every quarter of the globe beyond the most sanguine expectations of the people, if there be a man of whom the House of Bourbon stands more particularly in awe; if there be a man in this country who unites the confidence of England and America, is not he the proper person to treat with Americans, and not those who have uniformly deceived and oppressed them? There is not one present who is ignorant of the person to whom I allude. You all know I mean a noble, near relation, Lord Chatham." Many years later an able historian, reviewing the situation, repeated in no uncertain tone the substance of the speech of the promising young statesman. "There was one man to whom, in this hour of panic and consternation, the eyes of all patriotic Englishmen were turned," Lecky has written. "In Chatham England possessed a statesman whose genius in conducting a war was hardly inferior to that of Marlborough in conducting an army. In France his name produced an almost superstitious terror."[171]
