Poenius Postumus (d. AD 61), according to the Annals of Tacitus, was praefectus castrorum of the Roman Legion II Augusta, stationed in Britannia during Queen Boudicca'srebellion. While stationed near present-day Exeter with his troops, he ignored the call to join Governor Gaius Suetonius Paulinus in putting down the rebellion. Hearing of the Roman victory over the Iceni, he fell on his sword upon realizing he'd denied his troops the glory of victory.
