Historian Dan Jones sets out on a journey across Northern France, following in the footsteps of Edward III and his English army on their Crécy campaign - one of the earliest and bloodiest raids of the Hundred Years War.
Everything was going well for Edward and his dogs of war. They had made a successful landing and had ravaged the Norman countryside leading to the sack of the grand city of Caen.
But Edward's campaign is going to take a turn for the worse. On approaching the mighty city of Rouen, Edward learns that King Philippe VI of France, rather than shying away from action, had reinforced or destroyed all the bridges across the Seine between the sea and Paris. The English are forced deeper and deeper into France, trying to find a way across the river - with supplies running lower and lower - Edward finds himself in an increasingly desperate situation.A glimmer of hope is given to his campaign when he is able to force a way across at Poissy. But he now knows the French army is growing in strength and is hot on his heels.
Edward makes a dash north only to be faced with another obstacle. The River Somme. Now surrounded by the French army - he makes a last ditch effort to cross the river at a secret ford called the Blanchetaque. The English, desperate to cross push across the river and a bloody fight with French militia ensues.
Edward and his men, somehow make it across - only to find a few miles later that their time has run out - and Philippe VI now stands in front of him with 25,000 well fed men. The stage is set for the Battle of Crecy.
Meeting with Prof. Michael Livingston, Dan learns that the traditional battle site might be totally wrong - and he joins Michael at a new proposed site where he learns how the battle unfolded.
After the battle - Edward and his army - triumphant - march north to Calais where they lay siege to the city. And, after a year, the city falls into English hands where it would stay for 200 years.
