The scene pictured is incorrect. The bed Lincoln was carried to was too short for his frame and the room was lit by a single gas light. Lincoln was arranged diagonally on the bed, with his head toward the door and his feet over the edge of the opposite corner of the bed. The room was tiny, so small in fact, that Sec. Stanton had to set up a post in the adjoining room.
A total of sixteen doctors would see Lincoln that night, including the Surgeon General Joseph Barnes and the Lincoln family physician, Robert Stone. All of them realized the wound was fatal.
The sad fact behind Lincoln's death was that the more radical Republicans were able to use the assassination to further punish the south, beyond the moderate Reconstruction advocated by the late President.
Tough break, huh?
At a cabinet meeting on April 14, 1865, Lincoln advised the cabinet that wanted to return all the states back to normal relations before the Congress was able to come back into session. He instructed an irritated Stanton that Virginia was a special case and required special treatment. (Virginia was a special case because the U.S. government had recognized a Virginia government throughout the war.)
Naturally the insane, bloodthirsty radicals were incensed. After the bloodbath they had caused, one more life was cheap. Lincoln was shot that night. The radicals celebrated. Tough breah, huh?
