The True Story Behind Garfield’s Assassination


On July 2, 1881, Charles Guiteau shot President James Garfield at Washington’s Baltimore and Potomac Railroad Station. This wasn’t a spontaneous act of violence, but the culmination of months of planning by a man convinced he’d been wronged by the government.
The historical context reveals disturbing parallels to modern political violence:
- Guiteau believed in the “spoils system” of political appointments
- He felt entitled to a diplomatic position for supporting Garfield’s campaign
- When ignored, he developed messianic delusions about saving the Republican party



The Medical Tragedy
Garfield might have survived with modern medicine. Doctors probing his wound with unsterilized instruments caused fatal infections. This medical malpractice is depicted in horrifying detail in the series.
Guiteau’s Disturbing Psychology
Modern psychologists analyzing Guiteau’s behavior and writings suggest he likely suffered from:
- Paranoid schizophrenia
- Narcissistic personality disorder
- Religious delusions
The series brilliantly shows how these conditions manifested:
| Symptom | Depiction in Series |
|---|---|
| Grandiose delusions | Claims God chose him to kill Garfield |
| Paranoia | Believes political enemies are conspiring against him |
| Disorganized thinking | Rambling, contradictory courtroom speeches |



The Legal Aftermath and Public Spectacle


Guiteau’s trial became one of America’s first media circuses. The series recreates how his bizarre behavior fascinated and horrified the public:
- He acted as his own lawyer, delivering rambling speeches
- Sang hymns and recited poetry in court
- Claimed Garfield’s death was God’s will, not his fault
The insanity defense, relatively new at the time, became central to proceedings. Though clearly mentally ill, Guiteau was found competent to stand trial and sentenced to death.



Impact on American Law
This case influenced future legal standards for insanity pleas. The public outrage over Garfield’s death also helped end the spoils system of political appointments.
Historical Accuracy vs. Dramatic License
While mostly faithful to history, Death by Lightning takes some creative liberties for dramatic effect:
| Historical Fact | Dramatization |
|---|---|
| Guiteau bought the gun specifically for assassination | Shows him practicing shooting earlier |
| The fatal medical errors took weeks | Condensed timeline for narrative tension |
| Guiteau’s family mostly disowned him | Adds fictional scenes with his sister |



Why This Story Matters Today
Beyond being a gripping historical drama, Death by Lightning offers relevant commentary on:
- The dangers of unchecked political entitlement
- Systems that ignore mental health issues
- How media sensationalizes violence
- The human cost of political extremism
The series ultimately serves as both a character study and cautionary tale, with Macfadyen’s unforgettable performance ensuring this obscure historical episode resonates with modern audiences.
