Sir Josias Bodley (1550-1618) was an English military engineer noted for his service in Ireland during the Nine Years' War.
Josias spent some of his youth abroad, where his Protestant father had gone as a Marian exile during reign of the Catholic Mary I.
Bodley served during the Nine Years' War in Ireland, where Crown forces were battling against the rebellion of Hugh O'Neill, Earl of Tyrone.
At the decisive Battle of Kinsale Bodley was appointed as "Trenchmaster" (chief engineer) of the Anglo-Irish troops under Lord Mountjoy besieging a Spanish expeditionary force.
Bodley carried out a preliminary study of the terrain as a guide for London when the Ulster Plantation was being drawn up by James I and his government.
