Watch Bombuj. Neil Oliver and Tony Pollard set out to solve one of the biggest puzzles in battlefield archaeology. 700 years ago, Robert the Bruce's overwhelming victory over the English at the Battle of Bannockburn helped seal Scotland's future as an independent kingdom, although the actual location remains a mystery. With the help of leading battlefield archaeologists, stuntmen, computer-generated graphics and some digging, Neil and Tony go in search of both the real and imagined Battle of Bannockburn.
