Book Review

The War Against Rommel’s Supply Lines

Alan J. Levine

Four Stars out of Five

This is a very good book providing an in-depth analysis into the battle raging against the umbilical cord tying the Axis forces in North Africa to their base in Italy. In my opinion, no student of the war in the Mediterranean will be able to ignore it.

The book covers the whole of the supply struggle waged in the Mediterranean, but focuses on the period following the Alamein battles and the invasion of North Africa by US and British forces, when it became imperative for Allied planners to prevent a permanent lodging of Axis forces in Tunisia, to the surrender of Axis forces in May 1943. Five out of six chapters are devoted to this effort, while the first chapter provides a concise, yet highly informative and well-researched summary of what went on during 1940-42.

The focus chapters deal with the planning of the invasion of French North Africa, and in particular the role and establishment of 12th Air Force. The author describes well the troubles this formation went through when it was first established, and the very difficult command arrangements at the start of the campaign in Tunisia. The following chapters discuss the invasion, the attack against the build-up of Axis forces in Tunisia, which is rightly described in a very critical manner, the re-organisation of the forces engaged in the logistical battle from January 1943 onwards, and their contribution to the eventual victory. The book gives time to both US and British forces engaged in the battle, and is quite (and justly) complimentary to the Italian effort in keeping the Axis forces in Tunisia supplied.

The author manages well to weave a narrative integrating theatre strategy and individual actions, although at times the information packed into single sentences or paragraphs can become overwhelming. I am also not convinced about the need for as much detail as is sometimes provided and editing could maybe have parsed the text a bit more of unnecessary detail.

The book is very well-researched, going through archival material such as unit records of air formations engaged in the battle, or patrol reports of submarines, and it makes very good use of official histories, of both sides. This is a particularly outstanding feature of the book – where possible, the author made the effort of trying to verify claims made by Allied forces against air and sea targets, by checking the Axis records. While this is no doubt a thankless task, and often a wild goose chase, it is one that cannot be lauded enough. The author has also gone to good length in providing a background on the technical capabilities of the Allied weapons available for the task, highlighting the planes and submarines in particular.

The book sports an index, an extensive literature list, and a good set of endnotes – in other words, it is a serious research work. What is missing is a list of maps, although since there are only two, so maybe that was not considered necessary. Which leads me to: sufficient in number and detail maps are missing, so I recommend having an Atlas of WW2 handy while reading it, unless you have a North Africa map in your head. The selection of pictures is appropriate to the topic, and the quality is acceptable, especially considering the price. What I really would have liked to see are diagrams of air-sea attack formations. These are described verbally, but a picture would help very much in understanding the roles of the various planes engaging shipping targets. But that is really the only major gripe I can think of.

Thanks go to Stackpole for not only publishing a book that is clearly dealing with a somewhat esoteric topic (why bother with logistics - when you could have the umpteenth 750-page colour book about Waffen SS-Tigers?), but making the effort to create a very attractive presentation, and pricing it very reasonably. Highly recommended.

Small naval unit losses and damage

As promised, continuation from yesterday. The constant convoy battles took a toll on smaller units on both sides. This list is probably not complete - I have tried to ignore losses in the western Med, and in Greek waters, since these would not have been directly relevant to the North African convoy battle. I will eventually also add merchant shipping losses for the period. Sources are the two excellent sites Naval History Net and the Chronik Seekrieg site at the Landesbibliothek Stuttgart.

Italian Regia Marina/German Kriegsmarine

Destroyer

  • Fulmine (lost, surface engagement, 8/9 Nov 41)
  • Libecco (lost, sub torpedo, 9 Nov 41)
  • Euro (damaged, surface engagement, 8/9 Nov 41)
  • Grecale (damaged, surface engagement, 8/9 Nov 41)
  • Alvise da Mosto (lost, surface engagement, 1 Dec 41)


Escort Destroyer/Torpedo Boat

  • Alcione (lost after beaching, damaged by sub torpedo, 11 Dec 41)


Mine Hunter/Mine Layer

  • Zirona (damaged/beached, air attack, 25 Nov 41)
  • Cittá di Palermo (lost, sub torpedo, 5 Jan 42)

Submarines

  • Saint Bon (lost, sub torpedo, 4 Jan 42)
  • Caracciolo (lost, depth charges, 11 Dec 41)
  • U557 (lost, rammed in error by Italian escort destroyer, 16 Dec 41)
  • U79 (lost, depth charges, 23 Dec 41)
  • U75 (lost, depth charges, 28 Dec 41)
  • U374 (lost, sub torpedo, 12 Jan 42)
Commonwealth Royal Navy

Destroyer

  • HMS Kandahar (lost, mine, 19 Dec 41)
  • HMS Jervis (damaged, frogmen, 19 Dec 41)
  • HMS Ghurka (lost, sub torpedo, 17 Jan 41)


Sloop

  • HMAS Parramatta (lost, sub torpedo, 27 Nov 41)
  • HMS Flamingo (damaged, air attack, 7 Dec 41)

Submarines

  • HMS Perseus (lost, mine, 7 Dec 41)
  • HMS Triumph (lost, unknown, 31 Dec 41)
  • P.31/HMS Uproar (damaged, air attack, 14 Jan 41)

I think that these losses show quite clearly the commitment that the Regia Marina had to the convoys and the supply of Axis forces in North Africa. Something that is often not appreciated by those who think that the Italians were not pulling their weight.

Large naval unit losses and damage

A number of large naval units on both sides in the Mediterranean were either lost or severely damaged during the timeframe of the Crusader battle. I believe this list is complete, but if not, corrections are welcome. Small units and subs to follow. Sources are varied, include Italian Navy, Regiamarina.net, official histories, etc.

Italian

Battleships
  • Vittorio Veneto (damaged, sub torpedo, 14 Dec 41)

Heavy Cruisers
  • Trieste (damaged, sub torpedo, 22 Nov 41)

Light Cruisers
  • Duca degli Abruzzi (damaged, aerial torpedo, 22 Nov 41)
  • Alberto di Giussano (lost, surface encounter, 13 December 41)
  • Alberico da Barbiano (lost, surface encounter, 13 December 41)

British

Aircraft carriers

  • Ark Royal (lost, sub torpedo, 13 Nov 41)

Battleships

  • Barham (lost, sub torpedo, 25 Nov 41)
  • Valiant (damaged, frogmen attack, 19 Dec 41)
  • Queen Elizabeth (damaged, frogmen attack, 19 Dec 41)

Light cruisers

  • Neptune (lost, mines, 18 Dec 41)
  • Galathea (lost, sub torpedo, 15 Dec 41)
  • Aurora (damaged, mines, 18 Dec 41)

Supply statistics for North Africa

These are calculations I have done based on data in Dati Statistici Vol. I 2a Edizione USMMM Roma 1972.
Arrival rates of all military supplies in NA, Italian navy data, all units, volume of military supplies received in 1,000 tons:
Jul 41 - 81% (61.5kt)
Aug 41 - 87% (75.6kt)
Sep 41 - 79% (66.3kt)
Oct 41 - 76% (56.2kt)
Nov 41 - 26% (16.2kt)
Dec 41 - 78% (29.7kt)
Jan 42 - 100% (60.5kt)
Feb 42 - 100% (56.8kt)
Mar 42 - 80% (38.7kt)
Apr 42 - 99% (142.0kt)
May 42 - 92% (76.6kt)
Jun 42 - 79% (30.1kt)
Jul 42 - 92% (74.4kt)
Aug 42 - 66% (49.0kt)
Sep 42 - 81% (77.3kt)
Oct 42 - 50% (33.9kt)
Nov 42 - 74% (60.3kt)
Note that my guess is that non-arrived does not necessarily mean sunk, since it could also include convoys that departed but had to turn back (e.g. Convoy "C" on 24 November 41).
The figures very clearly show the extent of the autumn supply crisis, which almost cut off supplies to North Africa at the very moment the fighting reached the highest pitch of intensity of all year.
