In 54 BC, Caesar landed five legions and two thousand cavalry on the shores of Kent. Caesar repulsed the British counterattacks, crossed the Thames, and captured the king’s stronghold – the British were forced to sue for peace, to supply hostages, and to pay tribute to Rome. Almost one hundred years later, the emperor Claudius sent an expeditionary force to Britain. In 43 AD, fifty thousand men under the command of Claudius’ general, Aulus Platius, landed in Kent to begin the conquest of Britain. Within eight years Britain, from the borders of Wales to York (Eburacum), had been converted to a Roman province. The Romans showed no interest in the tin mines of Cornwall and never penetrated far into Devon or Cornwall.

The rich farmlands bordering the Fens provided grain for the Roman legions of the North. The grain was transported along the Fen’s natural waterways and on canals constructed by the Romans.

To prevent marauding tribesmen from raiding farms south of the Scottish border, the emperor Hadrian ordered a wall to be constructed from Solway Firth to the Tyne. A section of Hadrian’s Wall took strategic advantage of a the Whin Sill. Antonius Pius (138-161 AD) continued Hadrian’s policies against cattle rustling incursions at the northern border. Antonius pushed the frontier 75 miles northward, and ordered the construction of 37 miles of turf-clay wall between the firths of Forth and Clyde. The Antonine Wall had nineteen forts at two-mile intervals. Around 210 AD, the emperor Septimius ordered Hadrian’s wall reconstructed and led a military expedition into Scotland. Attempts to engage the Scots in battle were thwarted by the natives’ guerilla tactics.
By 400 AD, the weakening Western Roman Empire was under widespread attack by “barbarians.” North Sea tribes, the Angles, Saxons, and Jutes, raided Britain. In 408 AD, the Saxons made a devastating raid on Britain. By 428 AD, the Angles, Saxons, and Jutes were establishing permanent settlements along the British coast. The legions were permanently withdrawn from Britain around 442 AD, as the Western Roman Empire continued to collapse. In the hiatus created by their departure trade diminished, towns declined or disappeared, and roads fell into disrepair. Later settlement covered the traces of Roman field systems.

Some impacts of man on the environment by 500 AD
Areas of present day moorland were previously cultivated, suggesting that the soil was so degraded by agriculture that it is no longer arable. Fossil soils reveal evidence of degradation by erosional loss of physical constituents, and by their lost capacity to support a protective forest cover.
The inability to support a natural forest succession implies a concomitant decrease in the soil’s potential to produce food. The practice of manuring began in the second millennium, presumably in an attempt to maintain arable production. Some soils were abandoned quickly and did revert to woodland – this is seen particularly in some soils on limestone. Examples can be found in the Lowland zones, with the exception of the Wessex chalklands and the lowland heaths. However, soils were exploited excessively in some areas and never reverted to supporting the original flora – they became moorlands. Examples are to be found in the Highland zones, the Cumbrian Lakeland, and the Moors of the south-west. The Wessex chalklands have remained stripped of forest since the third millennium. The lowland heaths result from the agriculture-related podzolizing of Brown Earth into Gley soils, beginning in the third and second millennia BC.
