After the war, he became one of the proprietors and editor-in-chief of the Philadelphia Age, and retained that position for the remainder of his life. His literary work was confined mainly to editorial contributions to the columns of this journal. His only separate publication was The Case of Major André, a carefully prepared essay read before the Historical Society of Pennsylvania, which vindicated the action of George Washington. The immediate occasion was a passage in Lord Mahon's History of England that denounced the execution of André as the greatest blot upon Washington's record. By an authority so high as the London Critic, this essay was subsequently pronounced a fair refutation of Lord Mahon's charge.[1]
