Sumner's speech on the "Alabama claims" was considered a failure because the administration did not afterwards support him; and it is true that no government would submit to a demand for adventitious damages so long as it could prevent this; but it was a far-reaching exposure of an unprincipled foreign policy, and this speech formed the groundwork for the Treaty of Washington and the Geneva arbitration. It was a more important case than the settlement of the Northeastern boundary.
Sumner died the death of a hero. The administration of General Grant might well be called the recoil of the cannon: it was the reactionary effect of a great military movement on civil affairs. Sumner alone withstood the shock of it, and he fought against it for four years like a veteran on his last line of defence, feeling victory was no longer possible. Many of his friends found the current too strong for them; his own party deserted him; even the Legislature of his own State turned against him in a senseless and irrational manner. Still his spirit was unconquerable, and he continued to face the storm as long as life was in him. It was a magnificent spectacle.
It was the last battlefield of a veteran warrior, and although Sumner retired from it with a mortal wound, he had the satisfaction of winning a glorious victory. No end could have been more appropriate to such a life. _Dulce et decorum est pro patria mori._
Since Richard Coeur de Leon forgave Bertram de Gordon, who caused his death, there has never been a more magnanimous man than Charles Sumner. Once when L. Maria Child was anathematizing Preston S. Brooks in his presence, he said: "You should not blame him. It was slavery and not Brooks that struck me. If Brooks had been born and brought up in New England, he would no more have done the thing he did than Caleb Cushing would have done it,"--Cushing always being his type of a pro-slavery Yankee.
In 1871 Charles W. Slack, the editor of the Boston _Commonwealth_, for whom Sumner had obtained a lucrative office, turned against his benefactor in order to save his position. When I spoke of this to Sumner, he said: "Well, it is human nature. Slack is growing old, and if he keeps his office for the next six years, he will have a competency. I have no doubt he feels grateful to me, and regrets the course he is taking." At the same time, he spoke sadly.
