Mr. Lincoln approved a sitting with "the Crayon" which his son, Robert, had requested. Being familiar with Porte Crayon (David Hunter Strother), myself, as he was also a resident of Berkeley County, VA and a fine artist for Harpers Weekly, I approved the move. In this instance, however, I had not been consulted on this particular matter.
The president traveled by train to attend the Great Fair in Philadelphia in aid of the U.S. Sanitary Commission. There he spoke briefly saying "war, at the best, is terrible, and this war of ours, in its magnitude and in its duration is one of the most terrible. We accepted this war for an object, a worthy object, and the war will end when the object is obtained." He went on to predict that General Grant and the Union army was in place to never be dislodged until Richmond is taken.
Later that same evening he attended a reception and spoke at the Union League in Philadelphia. He returned to Washington the following day.
