Blurb

The Eagle and The Wolves is a 2003 novel by Simon Scarrow, the fourth book in the Eagle Series where main characters Macro and Cato command two cohorts of soldiers made up of warriors and nobles from the Atrebatan kingdom. This book follows their adventures in 44 AD during the occupation of Britain by Rome and Caratacus's following rebellion.
The book begins with the aftermath of the last book as Cato and Macro recover from their injuries in the city of Calleva. The Durotrigans are still at large raiding the Roman supply lines in Atrebatian territory. The Legate Vespasian with a small bodyguard come to investigate the stop of the supply lines, but is caught up in a skirmish to save a caravan of supplies. The raiders are only just fended off with most of the guards killed. The king Verica demands that Vespasian leave troops to protect the kingdom. Vespasian is unable to leave troops, but instead has Centurions Macro and Cato to train local troops. The two make good progress training two centuries of locals as Roman troops. The two centuries are named the Wolves and the Boars, and celebrate their first victory over a Durotrigan Raiding Party in an ambush.
