He was a royalist officer who was killed in action in the English Civil War. A seventeenth-century ode relating to four Cornish commanders included the distich:
They did not all fall at the same time, nor in the same place, but all four were killed in the year 1643. Slanning and Trevanion were slain at the siege of Bristol.
Sir Bevil Grenville fell at the Battle of Lansdowne near Bath, where an obelisk has been erected to his memory.
And Sir Sidney Godolphin was shot in the porch of the Globe lnn at Chagford in Devon.
Trevanion was a Member of Parliament, representing the Cornish boroughs of Grampound in the Short Parliament in 1640 and Lostwithiel in the Long Parliament from 1640 until his death in action at the siege of Bristol.
