It provided that if any person was convicted of conspiring to seize or destroy any castle or fortification held or garrisoned by the Queen's forces, then they and any associates were to be judged felons and suffer the death penalty without benefit of clergy or sanctuary. If any person was to prevent the use of any royal castle or ordnance by the crown, destroy any of the Queen's ships, or prevent the use of a harbour within the realm, then they were to be considered guilty of high treason and sentenced accordingly.
It specified that those found liable for conspiring against the Queen's strongholds would incur the death penalty without the right to pardon or sanctuary. Likewise, individuals who impeded the crown's use of its castles, destroyed royal vessels, or blocked access to ports within the realm would be regarded as high treason offenders and face corresponding retribution.
