The Britons proved to be some of the most determined foes that the Romans had ever met. Battle after battle was fought, and the country still remained unsubdued. Sometimes the Romans won, and sometimes the Britons were masters of the day. The Romans were trained soldiers, while their opponents were wild and undisciplined savages, but the Britons were fighting for their homes and freedom, and that made them very brave.

Among the British leaders the noblest was a chieftain of the name of Caradoc, or as the Romans called him, Caractacus. When some of the other chiefs, having been defeated many times, were forced to make peace with the invaders, Caradoc refused to yield. Fighting stubbornly, he contested every inch of southern Britain, but was slowly driven backwards to the mountains of Wales.

Here he gathered around him a band of Britons as brave and determined as himself, and for nearly nine years he held the Romans in check. The invaders, who did not know the country, were unable to penetrate far among these valleys, where thick forests hemmed in the view, and where every hillside might harbour a band of their savage foes.

It was impossible to reach Caradoc in this wild retreat. Accompanied by his followers, he would leave the mountains and sweep suddenly down upon a Roman camp in some distant part of the country. At a time when the Romans were least expecting it, a band of these wild, red-headed warriors would appear, yelling their war-cries as they let fly a shower of darts and arrows; then, after killing and wounding a number of the enemy, they would vanish among their mountains before the Romans had time to follow them up.

As years went on, a large number of Britons found their way to Caradoc in his Welsh retreat. The mountains became full of desperate men who had been driven from their homes, but were still determined to fight for freedom, and the example of their leader gave his followers fresh courage.

After many years of fighting, the Romans saw that the country would never be subdued so long as Caradoc should remain at liberty.

A great army was marched towards the stronghold of the daring chief. Caradoc mustered his retainers, and found himself at the head of a body of men almost as numerous as the Roman army. For nine years these Britons had remained unconquered; and the brave band hoped that the day had now come when they might gain a victory which would end in the invaders being driven out of the country.

Romans and Britons met on the borders of Wales.

The Britons, looking down from their mountains, saw the Romans on the plain far below. Between the armies there flowed a river, which was joined by a torrent rushing down by the side of a steep hill. Caradoc ordered his men to take up their station upon this hill, and all night long the Britons worked to strengthen their defences by building up barricades of loose stones.

When morning dawned the Britons could see the Roman legions forming in position. The sunbeams were glancing upon the crests of the soldiers' helmets and upon the points of their spears, and the Britons almost seemed to hear the voice of the general who was riding his prancing war-horse round the ranks of his army.
