"Omaha Beachhead," seventh of a series called American Forces In Action, is the first of a number of narratives dealing with U. S. military operations in France. Utah Beach to Cherbourg, planned for later publication, will round out the account of the invasion at corps level and below. Larger phases of the NEPTUNE operation, including high-level planning, naval operations, and the action of British units, are treated here only in outline. Omaha Beachhead was prepared in the field by the 2d Information and Historical Service, attached to First Army, and by the Historical Section, European Theater of Operations.
