Twelfth in the series of studies on particular combat operations, St-Lo is the story of a corps in the First Army during the bitter July battle that led up to and made possible the great breakthrough from the Normandy beachheads. This was the period of the most intense hedgerow fighting. XIX Corps' part in it has been chosen to illustrate this type of combat. The record of other First Army units in this operation have been covered only in outline.

Many illustrations.
