A unique and anecdote-filled history of desertion. There have been many books written about valour in battle. This is not one of them. On the contrary, On the Run deals entirely with those men and women who, over thousands of years, have departed with alacrity and for multifarious reasons from life in the armed forces. For as long as there have been wars there have been those who have fled, sometimes precipitously, from the cannon's roar.
