Before the Roman invasions of Britain, the area of Hampshire, Sussex, Surrey and Berkshire, were inhabited by a Celtic Tribe known as The Atrebates, one of the strongest and most powerful tribes in Britain at the time. They maintained connections with their related tribes in France (Gaul). 

As a result of those connections, the Atrebates had created positive relations with the Romans in France prior to any invasion of Britain, so when the invasion began from their landing point in Kent, led by Vespasian's  2nd Legion (Vespasian went on to become a Roman Emperor) they met with no opposition, and so therefore there are no Roman Battlefields in this area, until they met with the Celtic Tribe of Dorset, the Durotriges. After the Roman Conquest, the Atrebate territory was divided into three separate lesser areas, each with it's own Tribal capital, at Silchester (Calleva Atrebatum), Winchester, and Chichester.

The reason for the invasions and occupancy was due to the immense amount of iron and tin which were extremely important to the Romans. In smaller quantities there was gold and silver available. Easily available grain, wool and livestock also helped make Britain attractive for the Romans. 

There was very little Roman activity in the area now known as Church Crookham, probably due to the poor soil quality for sustaining crops, but within the surrounding area there are the ruins of a once substantial villa in Crondall ( Nat. Grid Ref. SU7947), evidence of a Roman pottery industry and more villa ruins in Farnham. The Romans had completely withdrawn from Britain by 410 A.D.
