A lawyer for Chelsea Manning has confirmed reports that she attempted to commit suicide last month at Fort Leavenworth, Kansas, where she is serving a 35-year prison sentence for violating the Espionage Act.

Manning had started a week of solitary confinement as punishment for a previous suicide attempt in July.

Manning gave a statement to The New York Times about the attempted suicide, which took place on October 4. In the statement, Manning simply states “evening – attempts own life in Disciplinary Segregation/Solitary.” Her lawyer, Chase Strangio of the American Civil Liberties Union (ACLU), confirmed to the Times that the attempt took place.

Most of Manning's four-page statement details events that took place on October 10, including an attempted attack on the prison by four people impersonating guards.

The Army in September agreed to provide Manning with medical treatment for her gender dysphoria after she staged a hunger strike. Manning's psychologist recommended the surgery in April.
