This is a quite impressive book that challenges a number of key assumptions about the "Roman Conquest" of Britain. Russell argues that many of the "Established Facts", as he calls them, are in need of a serious reassessment. He contends that the role of native British dynasts like Togodubnus has been greatly underestimated. In particular, he gives good arguments for British support of Claudius' invasion, both before and after the initial landings. He also shows that native British leaders may have played a far more significant part in overcoming Boudicca's Rebellion. Finally, he demonstrates that one of the early governors of Britain may well have been of royal British blood.
Profusely illustrated, the book's main strength is that all of this is presented in a clear, readable style. Russell gives a fair summation of past theories, then provides plausible evidence and arguments for what he sees as a better alternative. It is thus not just a book for academics but for anyone interested in this crucial period of British history.
The only quibble I would have is that the book may accept uncritically recent fashionable theories about "intertribal conflicts" during the Roman period. When Trinovantes are taking revenge on the Romans by burning Colchester, it seems strange not to simply attribute the burning of St Albans (and probably also Silchester and Winchester) to Catuvellaunians and Atrebates with similar grievances against both the Romans and their elite British quislings. At the very least, it would have been better to give good reasons why some tribes would not have had good reasons to resent the new Roman masters. That aside, this is a handsome volume, and belongs on the shelf of anyone interested in the Roman Empire in general, or Roman Britain in particular.
