Most Successful U-boat Commanders in the Mediterranean
The following table shows the most successful U-boat Commanders in the Mediterranean. Warships are included in these figures. After each man the U-boats he scored his successes in are shown. All men who sank ships in the Med are shown here. The data is calculated from the date a boat under his command entered the Mediterranean (and all subsequent attacks in the theatre).
