The German navy couldn't operate effectively in the Med and a U-Boat campaign there would have been foolish.
Not true. German U-Boats were very successfull in the mediterraean, especially against the supply convois for Malta:
13 November 1941 - As Force H returned to Gibraltar after flying off more Hurricanes from "Ark Royal" and "Argus" for Malta, the famous and much 'sunk' "ARK ROYAL" was hit by one torpedo from "U-81". Next day she foundered in tow only a few miles from home. One man was killed. "U-81" was one of four U-boats that had just passed into the Mediterranean.
25 November 1941 - Force K hunted for Italian convoys to North Africa supported by the Mediterranean Fleet with battleships "Barham", "Queen Elizabeth" and "Valiant". In the afternoon north of Sidi Barrani, "BARHAM" (above) was hit by three torpedoes from "U-331" and as she slowly turned over and capsized, split apart in an almighty explosion. Recorded on film her apparently calamitous end is often used in naval films and documentaries. Although over 800 men were lost with her, a remarkable number were saved. Just before this tragedy, Force K had sunk two more Axis supply ships west of Crete. At this stage 60 percent of Axis North African supplies were being lost to attacks by British aircraft, submarines and warships.
13 -20 Dezember 1941 - First Battle of Sirte and related actions - Italian convoy operations to Libya led to major Royal Navy losses over just a few days. A first Axis convoy bound for Benghazi set out on the 13th, covered by an Italian battlefleet. On receiving the news, Rear-Adm Vian left Alexandria with a cruiser force to join up with Force K from Malta. On the evening of the 14th, submarine “Urge” torpedoed and damaged battleship “Vittorio Veneto” off the Sicilian Strait of Messina and the Italians cancelled that operation. The cruiser forces returned to their bases but as they did, Adm Vian's “GALATEA” was hit by three torpedoes from “U-557” and went down off Alexandria that night. Adm Vian was out again late on the 15th to escort fast supply ship “Breconshire” from Alexandria to Malta. On the 17th they met Force K off the Gulf of Sirte, and shortly encountered Italian battleships covering a second convoy, this time to Tripoli. The two cruiser forces attacked and the Italians withdrew in what became known as the First Battle of Sirte. “Breconshire” reached Malta on the 18th and Force K left harbour to search for the second convoy still making for Tripoli. Early on the 19th off Tripoli, the British force ran into an Italian minefield. Cruiser “NEPTUNE” hit three or four mines and sank with only one man surviving. “Aurora” was badly damaged and “Penelope” slightly. Trying to assist “Neptune”, destroyer “KANDAHAR” was mined and had to be scuttled the following day. Out of a three cruiser and four destroyer force, only three destroyers escaped damage.
11 March 1942- Adm Vian's cruiser force returned to Alexandria after searching for Axis shipping and covering the passage of cruiser "Cleopatra" from Malta. North of Sidi Barrani, flagship "NAIAD" was torpedoed by "U-565" and went down.
12 -16 June 1942 - Malta Convoys 'Harpoon' from Gibraltar, 'Vigorous' from Alexandria - Six escorted merchantmen passed through the Strait of Gibraltar covered by battleship "Malaya", carriers "Argus" and "Eagle", cruisers "Kenya", "Charybdis", "Liverpool" and destroyers - this force comprised Operation 'Harpoon'. Attacks by Italian aircraft on the 14th led to the first merchant ship going down south of Sardinia. "Liverpool" was also damaged and had to return. Later that day at the entrance to the Strait of Sicily, the big ship cover force turned back. In the morning of the 15th, south of Pantelleria, an Italian two-cruiser squadron in conjunction with Italian and German aircraft attacked the by now lightly defended convoy. The five escorting fleet destroyers headed for the Italians, but "Bedouin" and "Partridge" were disabled by gunfire. Three more merchantmen were lost to bombing attacks and Italian torpedo aircraft finished off BEDOUIN. Later that evening, as the seriously depleted convoy approached Malta, it ran into a minefield. Two destroyers and the fifth supply ship were damaged, but Polish escort destroyer KUJAWIAK was sunk. Just two of 'Harpoon's' six ships reached Malta for the loss of two destroyers and serious damage to three more and a cruiser.
Meanwhile the Operation 'Vigorous' force of 11 ships and their escorts sailed from Haifa and Port Said, and were met on the 13th off Tobruk by Adm Vian with seven light cruisers and 17 destroyers. By the 14th, two ships had been lost to air attack and two more damaged. That evening Vian learnt an Italian battlefleet with two battleships, two heavy and two light cruisers plus destroyers had sailed south from Taranto. The chances of driving them off were slim. Early on the 15th the first of five (1-5) course reversals were made as 'Vigorous' tried to break through to Malta. As the convoy now headed back (1), German E-boats from Derna launched torpedo strikes. Cruiser "Newcastle" was damaged by "S-56" and destroyer HASTY sunk by "S-55". Around 07.00, when the Italian fleet was 200 miles to the northwest, the convoy turned back for Malta (2). Attacks by Malta-based aircraft were made on the main Italian fleet without serious effect, although they disabled heavy cruiser "TRENTO" which was finished off by submarine "Umbra". Between 09.40 and noon on the 15th, two more course reversals (3 & 4) were made so that once again the convoy was bound for Malta. All afternoon air attacks were mounted; and south of Crete, cruiser "Birmingham" was damaged and escort destroyer AIREDALE sunk by Ju87 Stukas. The convoy was now down to six ships when Australian destroyer "Nestor" was badly damaged. That evening 'Vigorous' finally turned back for Alexandria (course reversal 5). Now into the early hours of the 16th, cruiser HERMIONE was torpedoed and sunk by "U-205", and NESTOR had to be scuttled. At this time, as the Italian fleet headed back for Taranto, a RAF Wellington from Malta torpedoed and damaged battleship "Littorio". None of the 'Vigorous' ships reached Malta. One cruiser, three destroyers and two merchant ships had been lost in the attempt.
10-15 August 1942- Malta Convoy: Operation 'Pedestal' (map below) -For Malta to survive another convoy had to be fought through. The biggest operation ever was mounted from the Gibraltar end. A total of fourteen merchantmen, including two American and the British-manned tanker "Ohio" (Capt D. W. Mason) had a massive escort. Close in under Rear-Adm Harold Burrough were cruisers "Nigeria", "Kenya", "Manchester" and "Cairo" and 12 destroyers. Covering were the three fleet carriers "Eagle", "Indomitable" and "Victorious" each with their accompanying cruisers "Charybdis", "Phoebe" and "Sirius", battleships "Nelson" and "Rodney", and another 12 destroyers. Eight more destroyers sailed with the force - to give a total of 44 major warships. The opportunity would be taken for carrier "Furious" to fly off 38 Spitfires for Malta. The Mediterranean Fleet would try to distract the enemy at the other end of the Mediterranean. In overall command of 'Pedestal' was Vice-Adm E. N. Syfret. The convoy passed Gibraltar on the 10th and from the next day was subjected to increasingly intense attacks by submarines, aircraft and later coastal forces. Early on the afternoon of the 11th, "Furious" sent off her Spitfires and later that day headed back for Gibraltar. On the 12th one of her escorting destroyers "Wolverine", rammed and sank Italian submarine "DAGABUR" off Algiers. Still on the 11th and now north of Algiers, "EAGLE" was torpedoed four times by "U-73" and went down. Air attacks took place later that day and early on the 12th, but not until noon, south of Sardinia, did they gain their first success. Italian and German aircraft slightly damaged "Victorious" and hit a merchantman which later sank. More submarines then appearred and the Italian "COBALTO" was rammed by destroyer "Ithuriel". Once the convoy was north of Bizerta, Tunisia, submarine, aircraft and Italian MTB (mas) attacks came fast and furiously.
At 18.30, still on the 12th, aircraft badly damaged "Indomitable" putting her out of action and destroyer "FORESIGHT" was torpedoed by an Italian bomber and scuttled next day. The main Royal Navy cover force next turned back at the entrance to the 100 mile wide Strait of Sicily. The convoy carried on, still with 13 of the original 14 merchantmen afloat and its close escort of four cruisers and 12 destroyers. Disaster struck soon after 20.00 to the northwest of Cape Bon. Three out of the four cruisers were put out of action by Italian submarines. "Axum" and "Dessie" hit cruisers "Nigeria" and "Cairo" and the vital tanker "Ohio". "Alagi" torpedoed the "Kenya". "CAIRO" was scuttled and "Nigeria" headed back to Gibraltar. Around this time aircraft sank two transports. Cruiser "Charybdis" and two destroyers left the the main cover force and returned east to replace the lost ships. In the early hours of the 13th, the convoy was hugging the coast south of Cape Bon when Italian MTBs struck. Four merchantmen were sent to the bottom and the last of the original close escort cruisers, "MANCHESTER" was hit and scuttled. Air attacks later that morning accounted for one more merchantman and disabled another which was finished off in the evening. And to add to the torpedo hit, "Ohio" loaded with its highly inflammable cargo was now damaged by bombs and a crashing Ju87 Stuka. Including her, just five ships were left. Now into the afternoon of the 13th, three reached Malta. The fourth struggled in next day, but the crippled "Ohio", lashed to destroyer "Penn", only made port on the 15th. (Capt Mason was awarded the George Cross.) By now the close escort had just returned to Gibraltar.
Earlier, an Italian cruiser force set out to add to the convoy's miseries, but turned for home. North of Sicily on the 13th it was sighted by submarine "Unbroken" (Lt A. C. G. Mars) and heavy cruiser "Bolzano" and light cruiser "Attendolo" torpedoed and damaged. Only five out of fourteen transports had got through to Malta for the loss of one aircraft carrier, two cruisers and a destroyer sunk, and a carrier and two cruisers badly damaged. But the supplies delivered - and especially "Ohio's" oil - were enough to sustain Malta as an offensive base at a time critical to the coming Battle of El Alamein. More was still needed however, and only two days after "Ohio's" arrival, "Furious" flew off more Spitfires while submarines continued to make supply trips.
FEBRUARY 1944
Italy - In the Second Battle of Cassino, the attacking Indian and New Zealand troops took heavy losses for zero gains. Throughout the month the Germans launched more attacks at Anzio to prevent the Allies breaking out of the beachhead. By early March they had exhausted themselves and moved over to the defensive. Royal Navy ships continued to suffer casualties during the Battle for Anzio: 18th - Returning to Naples, the seemingly indestructible cruiser "PENELOPE" (HMS 'Pepperpot') was torpedoed and sunk by "U-410". 25th - A week later destroyer "INGLEFIELD" was hit off the beaches by a Hs293 glider bomb and went down.

This book is also about the missions of the german torpedoboats and speedboats/e-boats in the Mediterranean from 1941-1945.
If this thread is about german strategy in WW II could we please talk with more facts and less history fiction?
Fact is, Rommel's DAK was sent to Libya to defend Libya and prevent a allied invasion in Sicily and so to stabilize Mussolini's rule in Italy.
After the loss of Libya and Tunisia and the invasion of Sicily Mussolini was overturned, Italy made a separate ceasefire with the Allies and the italian armies and the big italian navy changed the sides. Much more new german forces needed to be sent to Italy from the eastern front.
Ergo: Exactly that happened, what the DAK should prevent, so the decision for sending forces to Libya was right, but to less and Malta, which was also on the route of the german-italian supply convois, was not taken, although the time in spring/early summer 1942 was fortunate because of the losses of the RN and the combined airraids of Luftwaffe and italian Aeronautica on Malta in Spring 1942 (Malta Blitz).
At this time the Axis had the less losses in their convoys to Libya.
