The firmness exhibited by Franklin on this occasion he never failed to exhibit in his later life whenever it was necessary for him to do so. Even John Adams, in 1778, though he had worked himself up to the point of charging Franklin with downright indolence and with the "constant policy never to say 'yes' or 'no' decidedly but when he could not avoid it," admitted in the same breath that Franklin had "as determined a soul as any man." If anyone doubts it, let him read the letters written by Franklin upon the rare occasions when he felt that, as a matter of justice or sober self-respect, he could not escape the duty of holding up the mirror of candid speech to the face of misconduct. On these occasions, his rebuke was like a bitter draught administered in a measuring glass, not a drop too much, not a drop too little. Witness his letter of March 12, 1780, to Captain Peter Landais in reply to the demand of that captain that he should be again placed in command of the _Alliance_. The demand, however [Franklin wrote], may perhaps be made chiefly for the sake of obtaining a Refusal, of which you seem the more earnestly desirous as the having it to produce may be of service to you in America. I will not therefore deny it to you, and it shall be as positive and clear as you require it. No one has ever learnt from me the Opinion I formed of you from the Enquiry made into your conduct. I kept it entirely to myself. I have not even hinted it in my Letters to America, because I would not hazard giving to any one a Bias to your Prejudice. By communicating a Part of that Opinion privately to you it can do you no harm for you may burn it. I should not give you the pain of reading it if your Demand did not make it necessary. I think you, then, so imprudent, so litigious and quarrelsome a man, even with your best friends, that Peace and good order and, consequently, the quiet and regular Subordination so necessary to Success, are, where you preside, impossible. These are matters within my observation and comprehension, your military Operations I leave to more capable Judges. If therefore I had 20 Ships of War in my Disposition, I should not give one of them to Captain Landais. All the higher forms of intellectual or moral power suggest the idea of reserve force, and of nothing is this truer than the self-controlled indignation of a really strong man like Franklin or Washington.
