A semi-interesting account of the Roman army's incursions into Britain, first in a all-too-brief invasion by Julius Caesar, and later by the emperor Claudius and his successors. Caesar came around 55 B.C. and left almost right away, while Claudius's forces started an actual occupation of the territory in 43 A.D. This occupation would last for almost five hundred years, but only the first forty or so years are dealt with by Cottrell since, as his title indicates, it is the invasion not the occupation with which he is concerned. By the last years of the Governorship of Agricola, around 84 A.D., the furthest limits of Roman power, which had by then spread to the southern part of Scotland, were essentially established.
The main difficulty I had with this work was that, unlike ancient Egypt, about which Cottrell also wrote, no actual written records survive. The Nile region is essentially arid; that of the British Isles is much the opposite: hence, paper records survive from the former but have been lost for the latter. Thus, a large part of Cottrell's work is a mere retelling of Caesar's own writings on his brief foray and the accounts of Agricola's battles penned by Tacitus, who was this Governor's son-in-law.
Archaeological evidence is often referred to, but other than establishing when this fort was built, is not much help in identifying the main issue I had: why did the Romans, rulers of the known world, choose to expand their empire to include this remote home of what they largely regarded as barbarians? Cottrell rather weakly answers the question thus:
Britain was a thoroughly unattractive place; wet, misty and dull, the home of barbarians, distasteful to a civilized, Mediterranean man. Yet there it was - a challenge. Because it was there.
The most telling point I hadn't appreciated before reading this work was the overwhelming cosmopolitanism of the Romans. Their four legions with which they occupied Britain were drawn not only from Italy, but also from Gaul, Syria, Africa, Germania and even the British Isles themselves. There was little if anything purely 'nationalistic' about their imperialism. Anyone could become a Roman citizen, or even Emperor, and though they kept slaves, those falling into this status did not do so because of their race or territorial background. Most were simply unfortunate in being on the losing side in a battle.
On battles this book is quite good. The rebellion of Boudicca which nearly succeeded in throwing the Roman forces back into the sea is well described, but an even more stirring narrative is reserved for the battle of Mona Graupius of Agricola against Calgacus. In both cases, the exceptional discipline of the Roman forces overcame the passionate, spirited but somewhat disorganized forces opposing them.
Cottrell's final pages make the argument that the main effect of the nearly five hundred years of Roman rule of his country were some quite good roads.
Needless to say, I found this work somewhat underwhelming.
