"My series of stories dealing with the wars of England would be altogether incomplete did it not include the period when the Romans were the masters of the country. The valour with which the natives of this island defended themselves was acknowledged by the Roman historians, and it was only the superior discipline of the invaders that enabled them finally to triumph over the bravery and the superior physical strength of the Britons. The Roman conquest for the time was undoubtedly of immense advantage to the people-who had previously wasted their energies in perpetual tribal wars-as it introduced among them the civilization of Rome."
