A valuable look at the highly successful Allied effort to interfere in Axis supply lines to North Africa during the Tunisian Campaign. The author has done a good job of integrating the naval and air aspects of the story, provides adequate coverage of the Axis side, and refrains from trying to find scapegoats. However, the book might have benefited from some tables to better illustrate the Axis supply problems. Of particular value for anyone interested in the war in North Africa.
