Season 3

After months of rising tension, the English Civil War finally exploded into life on the slopes of Edgehill on the 23rd of October 1642. It was to be a confused and bitter business, marked by the foolishness of Prince Rupert and the Royalist cavalry, who left the field at a crucial stage of the battle. As darkness fell, nearly 3000 men lay dead and the die was cast: the English Civil War would be no short and decisive affair.

The Battle of Naseby on the 14th of June 1645 all but decided the outcome of the English Civil War. As the sun set on a dramatic day, the Oxford field army of King Charles had been comprehensively beaten and completely destroyed. The King had shown considerable personal courage during the battle, however his cause was not helped by Prince Rupert's infamous attack on the baggage train, which meant that the day was lost before he could return to the field.

In a mighty attempt to crush the Scots, King Edward II placed himself at the head of the invasion of Scotland. In their desperate hour of need came Scotland's greatest medieval king, Robert, known simply as "The Bruce". The two forces would meet at a small stream within sight of Stirling Castle - the Bannockburn. The thunderous battle fought there would decide the fate of a nation.

The Battle of Marston Moor on July 2nd 1644 was one of the most important of the entire English Civil War. It was here that a force of some 27,000 Parliamentarian and Scottish troops routed an army of just 18,000 Royalists. Crucially, the Royalist stronghold of York was lost and King Charles' cause in the north virtually collapsed. It was a defeat from which the King would never recover.

During the long years of the Dark Ages, the sight which signalled fear and terror for the inhabitants of coastal Britain was the first glimpse of an unfamiliar sail on the horizon.

The great battle fought near the English seaside town of Hastings on October 14th 1066 was perhaps the most significant in England's history. The great victory won that day by Duke William of Normandy over Harold II of England was to shape forever the destiny of a nation. For at the end of a day of furious battle, the sun set not only on the dead and wounded who littered Senlac Hill, but also on the entire Anglo-Saxon way of life.

In 58 BC, Julius Caesar pushed north from Rome into the unruly lands of the barbarians. Less than eight years later, the empire extended all the way to the Atlantic, and Roman legions were making incursions into Britain. The key to Caesar's victory lay not in the superiority of the Roman war machine but in his mastery of strategy, tactics, discipline and military engineering. According to Plutarch, Caesar's campaign resulted in 800 conquered cities, 300 subdued tribes, a million slaves and 3-million dead on the battlefield - all this, not to mention Caesar's elevation to First Man in Rome.

In 55 BC the ambitious Julius Caesar, Emperor of Rome, turned envious eyes towards the mysterious isle called Britain. Within a few short years, the mighty Roman war machine had tamed the Celtic tribal society and transformed it into a province of the Roman Empire. This is the story of the dark years of ancient Britain when the well-disciplined Roman legions faced the fury of the united Celtic peoples of Britain.
