19. The positive value of CORSICA to the UNITED NATIONS is small once SICILY and SARDINIA have been occupied, unless further amphibious operations against SOUTHERN FRANCE or NORTHERN ITALY are envisaged. In this case seizure of CORSICA would, of course, be essential in order to protect the lines of communication. 20. The negative value of CORSICA resulting from denial to ITALY could be considerable, however, if full use is to be made of SARDINIA as an advanced air base for a heavy bombing offensive of the industrial areas in NORTERN ITALY. Neutralization by air from SARDINIA of Italian airfields in CORISCA is no more likely to be permanently successful than AXIS efforts to neutral- ize MALTA from SICILY, and the only sound alternative is denial of airfields by occupation of CORSICA. Four hundred and eighty AXIS aircraft based on CORSICA (estimated capacity of potential airdromes) would require the bulk of UNITED NATIONS air forces on SARDINIA to be defensive, but could not prevent the use of SARDINIA for forward airdromes, nor to a limited extent for an offensive bomber base. The probable maximum of 150 German air- craft would not seriously interfere with Allied use of SARDINIA. 21. Possession of CORSICA will have no appreciable effect on the security of the West-East MEDITERRANEAN SEA route once SICILY sad SARDINIA are in our hands. 22. Failure of the UNITED NATIONS to occupy CORSICA will reveal to GERMANY that no surface action against SOUTHERN FRANCE or NORTHERN ITALY is tobe initiated; conversely, occupation of CORSICA will immediately force GERMANY to strengthen her NORTHERN MEDITERRANEAN defenses CONCLUSIONS 23. The immediate strategic value of CORSICA to the UNITED NATIONS lies in the denial of its use by the AXIS to interfere Appendix "B" - 16 - |
