Enemy ships in the harbour of Gibraltar have been in the sight of the Royal Italian Navy since September 1940. After several attacks by “Gamma” frogmen and SLC units, ideas to build a secret base of the Decima MAS were realized in the second half of the year 1942. Convoy ships for the United States were beginning to arrive in quantity. The numbers of potential targets at anchor in the Bay of Algeciras were growing almost daily.

Earlier in 1942, a base for the Decima MAS “Gamma” frogmen was established in the Villa Carmela near La Linea from where several missions were carried out against British merchant ships (see page 126-131 / chapter II.I). During the months of shaping Villa Carmela into an advanced base, the idea for a bigger and much more effective operation had taken form in the mind of Licio Visintini, one of the SLC pilots of the mission B.G.4 in September 1941 (see page 374-381 / chapter II.III) which was carried out from the submarine Scirè.

Before the new base was ready for action, each attack at Gibraltar had required a long submarine voyage, air and land transportation of the attack-teams, the shipping of supplies and weapons, arrangements for rendezvous, an approach by submarine, and finally the task of smuggling the survivors back to Italy thru neutral Spanish territory.

Licio Visintini’s idea became real with turning the anchored ship Olterra inside the pier of Algeciras into a secret base for SLC missions. Visintini and further technical specialists replaced the original crew of the Olterra. An assembly workshop for the SLC devices (which arrived in sections, declared as spare parts for the damaged ship) was established in the hull. A portside cabin of the Olterra became the observation post with an excellent view of Gibraltar harbour. Finally, a folding door on the port side bow (see coffee table shot of page 386-387 /chapter II.III) became the exit door for the SLC units below waterline to reach their targets – and to return back into the hull of the Olterra. After months of intensive work in total secrecy, the inconspicious ship Olterra was turned into a Trojan Horse – “il cavallo di Troia” – and six men were ready for action with their SLC devices.

The Olterra was starting point of the following SLC missions against enemy ships in the bay of Algeciras / Gibraltar harbour: B.G.5 (7/8 December 1942), B.G.6 (7/8 May 1943) and  B.G.7 (3/4 August 1943). Our book “The References” 1930’s-1940’s features two Ref. 3646 watches which were used during these missions.

The Ref. 3646 / Type A “Radiomir Panerai” watch of Ernesto Notari is featured in chapter II.I (page 58-91 / see coffee table shot on the left) – more on this watch and its history can be found here. The Ref. 3646 / Type C “Radiomir Panerai” watch of Licio Visintini is featured in chapter II.III (page 350-367) – more on this watch and the history behind can be found here. The new “The References” books can be ordered only in our bookstore.

1940. The first mission against the Port of Gibraltar (B.G.1) was aborted when it became clear that the British fleet had already left for Operation “Menace”. The transport submersible Scirè under the command of Junio Valerio Borghese was still 50 nautical miles off Gibraltar. Disappointed, the SLC teams returned to their secret base at Bocca di Serchio, where they intensively discussed the feasibility of this type of attack. This happened at the same time when „Operazione G.A.2“ was about to end with the sinking of the transport submersible Gondar.

Initial, decisive proof of the feasibility and the successful, secret penetration of enemy ports was achieved by Comandante Borghese and his men in mission B.G.2. Again, three SLCs were dispatched: Teseo Tesei with Alcide Pedretti, Luigi Durand de la Penne with Emilio Bianchi and Gino Birindelli with Damos Paccagnini.

The Scirè came into position at around 1.30 a.m. on 30 October 1940 in order to allow the SLC teams to disembark from the conning tower of the submersible. The Scirè only remained at the surface for a short time so that the three SLC teams could reach the cylindrical pods on the deck of the submersible. The Scirè then retreated back beneath the surface. Under water, the three teams manoeuvred their SLCs out from the pods and started their attack on the Port of Gibraltar. The three teams experienced problems almost as soon as the attack began. While Tesei and his co-pilot Pedretti had problems with their breathing apparatus, Durand de la Penne and his co-pilot Bianchi experienced problems with their electric engine. Both teams decided to abort the attack and sink their SLCs. However, only De la Penne managed to do this. Tesei’s SLC was washed up on the Spanish coast near La Linea and caused quite a stir among both the Spanish authorities and the British secret service. Both teams swam to the Spanish coast and were able to return safely to Italy with the help of the Italian secret service.

The fate of the entire operation now lay in the hands of Gino Birindelli and his co-pilot Damos Paccagnini. Unaware of the fact that their comrades-in-arms had already had to terminate their mission, they launched their attack on the Port of Gibraltar. Although mission B.G.2 was in principle a failure because not one enemy ship was sunk, Birindelli and his co-pilot Paccagnini were able to prove for the first time that a “maiale” was able to enter an enemy port unnoticed.

„Operazione B.G.2“ marked the start of a three year war that took place noiselessly and under water in the Bay of Gibraltar. For Gino Birindelli, however, the mission marked the start of a journey through Allied POW camps that would last many months. Read more on mission B.G.2 and the story of Gino Birindelli in our book “The References” 1950’s-1960’s in chapter VIII.II on page 1014-1043.

The afternoon of 30 September 1940 marks the end of the mission „Operazione G.A.2“. Just five weeks after the sinking of the Iride, the Gondar (photo: historic crest of the submarine, showing SLC containers on its deck) was the second transport submarine of the Mezzi d’Assalto to be sunk.

The submarine Gondar (built in 1937) under the command of Tenente di Vascello Francesco Brunetti was dispatched from La Spezia with Alexandria as her target. On board the Gondar was the officer-in-charge of mission G.A.2, Mario Giorgini, three SLC teams and a reserve team.

When the Gondar reached the target area on 29 September 1940, she received a sobering radio message from reconnaissance: The British fleet had left the Port of Alexandria – so mission G.A.2 was aborted. The Gondar headed now for Tobruk and was already on its return journey when it was discovered by the Australian destroyer, HMAS Stuart. A second destroyer, HMS Diamond and a corvette now tracked the Gondar throughout the night alongside HMAS Stuart.

After hours of attempting to evade capture, the Gondar gave up in the early hours of 30 September 1940. Commander Brunetti gave the order to dive down and abandon the Gondar, which effectively saved his team and the SLC pilots from going down after being sunk by the mighty enemy. A British Sunderland flying boat bombarded the Gondar while the crew was already in the water – effectively sealing the fate of the second transport submersible for SLCs (see historic photos on the left). For one of the two inventors of the new weapon, Elios Toschi, this second journey was also to be his last. He was taken prisoner by the British alongside the crew of the Gondar and his comrades – “missione fallita”.

The launch of the new weapon appeared to be ill-fated: Two operations (G.A.1 and G.A.2) failed, two valuable transport submersibles had been sunk and four SLC teams and their officers-in-charge had been taken as prisoners of war. It was to take over a year until another attempt could be made to penetrate the Port of Alexandria in December 1941…

Mario Giorgini, officer-in-charge of the mission G.A.2 is also featured in the second volume of “The References” on page 1016-1022. The Gondar is also featured in our book “History1” in chapter IV on page 288-357.

Gulf of Bomba (Lybia). In August 1940, the time had finally come to put the new SLC weapon to the test. Alexandria in the eastern Mediterranean was the main base of the British Mediterranean fleet. The battleships at anchor there were the first targets for missions of the Mezzi d’Assalto involving the SLCs.

The transport submersible Iride, under the command of Tenente di Vascello Francesco Brunetti, prepared for its tour of duty with the SLCs on 21 August 1940, ready to attack the Port of Alexandria in the night of 25/26 August 1940. Eleven servicemen with four SLCs aboard the torpedo boat Calipso were dispatched to the Gulf of Bomba on the Libyan coast. There, the SLCs were tested at held ready for departure until they were ready to launch mission G.A.1 a few days later with the submersible Iride.

Right at the start of its test run, however, the submersible Iride was spotted by three Fairey Swordfish torpedo bombers, which had launched from the aircraft carrier HMS Eagle. The enemy bombers began their attack straight away (see historic map on the left).

The shallow water in the Gulf of Bomba prevented the Iride from descending quickly. Instead, it attempted to ward off the attack at full speed with its anti-aircraft cannons. At the same time, Brunetti tried in vain to direct the bow of the submersible towards the attackers in order to reduce the area of the Iride exposed to attack. However, the Iride was soon hit by a torpedo and sank. The boats quickly dispatched to the scene managed to rescue some of the shipwrecked crew members from the Iride. A dramatic race against time began.

The SLC teams under Gino Birindelli (right in the photo), Teseo Tesei, Elios Toschi, Luigi Durand de la Penne and Emilio Bianchi dived straight down to the wreck of the Iride in order to save the survivors who were trapped down there. Although the equipment belonging to the SLC pilots on board the Iride was lost, but the three SLCs were recovered for use in later missions. The SLCs pilots returned to the Bocca di Serchio on board the Calipso.

During the rescue of the survivors from the Iride, they had pushed themselves to the very limit of what was humanly possible. Loss of human life and equipment was the sobering result of the first mission „Operazione G.A.1“ with the new weapon of the Mezzi d’Assalto.

Augusta (Sicily) 11 pm. The night of 25 July 1941 marks the beginning of the “Operazione Malta 1”, known by its disastrous result for the Mezzi d’Assalto, only three months after the first successful attack with MT explosive boats against British ships in Souda Bay (Crete) on 26 March 1941. One day later, in the early morning of 26 July 1941, the Decima MAS lost the head of the flotilla (Capitano di Fregata Vittorio Moccagatta), the head of explosive boats (Capitano di Corvetta Giorgio Giobbe), the doctor of the flotilla (Tenente Medico Bruno Falcomatà), SLC pilots (including their inventor, Teseo Tesei) and MT explosive boats pilots during the attack of the harbour of La Valetta (Malta).

On a side note of the history, the commander of the explosive boats / “Mezzi di Superficie”, Giorgio Giobbe (1906-1941), is well known for wearing his Panerai watch on his right wrist in a photo taken prior the mission against Malta (see page 111-115 in chapter II.I). More about missions and watches of the Decima MAS can be found here.

Without a doubt, Luigi Ferraro was a man whose entire life was shaped by the sea. As a talented swimmer, he had been fascinated by the element of water since his youth. During the Second World War, he became one of the best-known frogmen of all time and showed great courage and skill during his dangerous missions, taking himself into the very limits both physically and mentally.

His Radiomir watch, a Ref. 3646 / Type B with riveted plastic dial, has been with him since he was a “Gamma” frogman in the Second World War. With the kind support of his family we were able to document his watch in chapter II.II of our book “The References” together with a view onto his life – before, during and after the war.

Page 194 – 195: View on the engraved caseback of Luigi Ferraro’s 3646 / Type B.

In January 1943, Luigi Ferraro obtained his qualification to carry out underwater missions. He was first posted to North Africa, where he was to attack ships from the British armed forces in the Port of Tripoli. Before the attack could take place, he was ordered back to Italy. Soon later he became an instructor for “Gamma” frogmen of the Mezzi d’Assalto. In May 1943, he was posted to La Spezia and received instructions from Junio Valerio Borghese for a new mission – this time, in the eastern Mediterranean.

Luigi Ferraro carried out four missions during July and August 1943 in the Turkish ports of Alexandretta and Mersina. These four missions resulted in the sinking of two ships and the deactivation of a third. Undiscovered and highly successful, the “Operazione Stella” was one of the most effective operations of the Mezzi d’Assalto. Luigi Ferraro was awarded with the M.O.V.M. (gold medal for galantry at war) in the rank of Tenente Artiglieria.

Page 210 – 211: Sketch of two of the four “Stella” missions carried out by Luigi Ferraro in Alexandretta.

After his time as a “Gamma” frogman, he used the skills and abilities he had learnt in the war for civilian purposes. He was able to pass on his extensive knowledge and significant experience to countless divers. Luigi Ferraro was promoted by the Marina Militare to Capitano di Fregata di Complemento in the year 2000.

The watch of Luigi Ferraro (1914 – 2006) and the history behind can be read in the book “The References” 1930’s-1940’s (chapter II.II, page 190 to 225). Read more on “Operazione Stella” here. Enjoy reading!
