Dr Who encounters some of the most adventurous — and hardiest — characters in history as he journeys through time to meet the Conquerors. Not surprisingly the Doctor becomes mixed up in a few adventures himself as he witnesses Julius Caesar's invasion of Britain, Napoleon's triumph at the battle of Austerlitz and Hannibal's crossing of the Alps. Dr Who Discovers The Conquerors is one of a new series of illustrated Dr Who books. Watch out for other titles of Dr Who's journeys of discovery.
