Mathews and two of his American cohorts were arrested last year by the FBI.
Prosecutors wrote in a 45-page sentencing memo filed in Maryland District Court last week that Mathews was working alongside a white-supremacist group and was planning to kill on a large scale hoping to start a civil war.
The defence documents have been sealed and are not publicly available.
Mathews is scheduled to be sentenced on Oct. 28.
