Inside were Seward's Army nurse, Sergeant George F. Robinson, and Fanny Seward. Powell slashed Robinson on the forearm, and the soldier fell. Lewis pushed Fanny aside and leapt onto the bed. He savagely began knifing Seward in the face and throat. Seward, however, was wearing a metal and canvas splint on his jaw, which deflected most of Powell's blows. However, Powell managed to cut through Seward's right cheek and along his right throat, causing a large amount of blood flow. Believing Seward to be dead, Powell hesitated. Terrified of Fanny's screams of “Murder!”, Herold fled on his own steed, leaving Lewis Powell on his own to escape from Seward's mansion. Just as John Wilkes Booth mortally wounded President Lincoln at Ford's Theatre, Seward's other son, Augustus Henry Seward, burst into the room. Powell stabbed him several times after Augustus dragged Powell onto the floor. Robinson and Augustus Seward wrestled with the strong, uninjured Powell. Powell stabbed Robinson in the shoulder and slashed a portion of Augustus' scalp from his head. Powell was confronted by State Department messenger Emerick "Bud" Hansell in the hallway. Hansell had just arrived at the house moments earlier and found the front door ajar. As Hansell turned to flee, Powell stabbed him in the back. Powell ran out of the house, yelling “I’m mad! I’m mad!” Then he threw his knife in the gutter of the street, got onto his waiting horse, and disappeared throughout the night.

Powell had almost no knowledge of the streets of Washington, D.C., and without Herold he had no way of locating the streets he was to use for his escape route. He mounted his horse, and began riding at a relatively slow pace north on 15th Street. Powell's exact movements from the time he was seen cantering up 15th Street until the time he appeared at the Surratt boarding house three days later are not clear. It is well-established that he ended up (by riding or walking) in the far northeast part of the District of Columbia near Fort Bunker Hill, where he discarded his overcoat. In the overcoat pockets were Powell's riding gloves, a false mustache, and a piece of paper with Mary Gardner's name and hotel room number on it. Sources differ widely on what happened. Historian Ernest B. Furgurson says Powell's horse gave out near
