The Great Invasion by Leonard Cottrell is a military history describing the invasion of England by the Romans. The work starts with Julius Caesar’s rather aborted invasion. The largest section is made up of the discussion of the campaign under Claudius. The book concludes with the final operations near the end of the 1st century. 

          It is based on archaeological as well as primary source analysis. This was originally published in 1962 so there have been recent archaeological finds he didn’t know about. Descriptions of campaigns and battles are clear. Cottrell is conscious that he is writing for people who may have first hand experience of combat in World War II. He draws comparisons some more questionable than others.
