From The Age of Fighting Sail: The Story of the Naval War of 1812, by C. S. Forester (Doubleday, 1952; eNet, 2012), Kindle Loc. 3497-3519:
The object of every war, or threat of war, is, in a final analysis, to bring about such a state of mind in the other party that he does not want to make war. The will of the enemy is the ultimate objective, as Hitler was never tired of preaching, and as Clausewitz understood in those moments when he was not engrossed in the means to the exclusion of the ends. By 1814 both England and America had reached that state of mind. Mr Madison’s conversion was the product of many factors: the failure of the invasion of Canada, the emptiness of the Treasury (resulting from the British blockade) and the fall of Bonaparte. It must be remembered that Mr Madison took the important step of waiving his demands regarding impressment in June 1814. Yet it would be hard to withstand the conclusion that the greatest factor was the presence of a British squadron in the Chesapeake; it was with those topsails almost in sight that Monroe sent off the crucial dispatch. Naval and military factors brought about the British change of heart, the defeat at Lake Champlain, and the repulse—almost bloodless though it was—at Baltimore, and the continued presence of American privateers in British home waters. Finally it was the threat of further military operations—the continuance of the blockade and the menace of Cochrane’s roving army—that kept the American commissioners amenable and facilitated the negotiations.
Once peace came to appear desirable every step was taken to hurry its coming. Debatable questions were ignored or postponed for future discussion. Two hundred written words, even with all the ‘whatsoevers’ and the legal redundancies, affirmed the peace; hardly more were necessary to settle the very difficult questions arising out of a definition of the war’s end in all parts of the world, and a hundred words decided the fate of the prisoners. By contrast it took some thousands of words to set up a future commission to clear up the debatable points left over from the Peace of Paris, now thirty years old. The question of the Indians was solved—or postponed—by specifically including them in the treaty of peace, in two brief paragraphs. One single article, of fifty words, made declaration of the intention of the United States to abolish the slave trade; its presence was an indication of the power and determination of the benevolent enthusiasts of Britain as compared with the more fitful influence of the war party.
The shelving of the debatable points was denounced by some intelligent people on both sides of the Atlantic, on the grounds that it would lead eventually to a renewal of the war. They were proved in the event to be wrong; the memory of the profitless damage done by the war persisted, and was as influential in the minds of those responsible for keeping the peace as the knowledge of it had been in the minds of those responsible for making the peace. The boundary questions were settled amicably, and from there it was an easy step to the neutralization of the American-Canadian border, an achievement in the cause of peace so beneficial, and so far ahead of its time, as almost to justify the bloodshed and misery of the tragic war.
