In the weeks leading up to the assassination attempt, Lawrence began observing Jackson's movements. Witnesses later testified that Lawrence was often seen sitting in his paint shop muttering to himself about Jackson. On Friday, January 30, 1835, the day of the assassination attempt, Lawrence was seen sitting in his paint shop with a book in his hand while laughing. Lawrence suddenly got up, left the shop and stated, "I'll be damned if I don't do it." Later on that same day, Jackson was attending the funeral of
South Carolina Representative
Warren R. Davis at the
U.S. Capitol. Lawrence originally planned to shoot Jackson as he entered the service but was unable to get close enough to him. However, by the time Jackson left the funeral, Lawrence had found a space near a pillar on the East Portico, where Jackson would pass. As Jackson walked by, Lawrence stepped out and fired his first pistol at Jackson's back; it misfired. Lawrence quickly made another attempt with his second pistol, but that also misfired. It was later determined that the weapons that he had chosen were noted for being vulnerable to moisture, and the weather on that date was humid and damp. Lawrence's unsuccessful attempts were noticed by Jackson, who proceeded to beat Lawrence with a cane. The crowd, which included U.S. Representative
Davy Crockett, eventually intervened and wrestled Lawrence into submission. Lawrence was the first person to attempt to kill a sitting U.S. president. ==Trial and commitment==
