Guiteau believed himself to be largely responsible for
Garfield's victory. He insisted he should be awarded an ambassadorship for his vital assistance, first asking for Vienna,
then deciding that he would rather be posted in Paris. His personal requests to Garfield and to cabinet members (as one of
many job seekers who lined up every day) were continually rejected; on May 14, 1881, he was finally told personally to
never return by Secretary of State James G. Blaine (Guiteau is actually believed to have encountered Blaine on more
than one occasion). Guiteau then decided that God had commanded him to kill the ungrateful president.
Borrowing $15, he went out to purchase a revolver. He knew little about firearms, but did know that he would need a
large caliber gun. He had to choose between a
.442 Webley caliber British Bulldog revolverwith wooden grips and one
with ivory grips. He wanted the one with the ivory handle because he wanted it to look good as a museum exhibit after
the assassination, but he could not afford the extra dollar. (The revolver was recovered and even photographed by
the Smithsonian in the early 20th century but has since been lost). He spent the next few weeks in target practice—the
kick from the revolver almost knocked him over the first time-and stalking Garfield.
On one occasion, he trailed Garfield to the railway station as the President was seeing his wife off to a beach resort
in Long Branch, New Jersey, but he decided to shoot him later, as Garfield's wife, Lucretia, was in poor health and Guiteau
did not want to upset her. On July 2, 1881, he lay in wait for Garfield at the (since demolished) Baltimore and Potomac
Railroad Station, getting his shoes shined, pacing, and engaging a cab to take him to the jail later. As Garfield entered
the station, looking forward to a vacation with his wife in Long Branch, New Jersey, Guiteau stepped forward and shot Garfield
twice from behind, the second shot piercing the first lumbar vertebra but missing the spinal cord. As he surrendered to authorities,
Guiteau fired with the exulting words, repeated everywhere: "I am a Stalwart of the Stalwarts. .. Arthur is president now!!'"
After a long, painful battle with infections, possibly brought on by his doctors' poking and probing the wound with unwashed
hands and non-sterilized instruments, Garfield died on September 19, 11 weeks after being shot. Most modern physicians familiar
with the case state that Garfield would have easily recovered from his wounds with sterile medical care, which was common in the
United States 10 years later.
