The Battle of the Espero Convoy (Battaglia del convoglio Espero) on 28 June 1940, was the first surface engagement between Italian and Allied warships of the Second World War. Three modern {{convert|36|kn|mph km/h|lk=in|abbr=on}} Italian destroyers made a run from Taranto for Tobruk in Libya to transport Blackshirt (Milizia Volontaria per la Sicurezza Nazionale) anti-tank units, in case of a British tank attack from Egypt.

By coincidence, the Mediterranean Fleet was at sea to conduct a destroyer anti-submarine sweep around Crete and provide cover for three Allied convoys to Egypt, one from Turkey and two from Malta. British aircraft from Malta spotted the Italian destroyers and the 7th Cruiser Squadron turned to intercept them and a running fight took place south-west of Crete, in which the destroyers were impeded by their cargoes and an adverse sea.

The Italian destroyer Espero (Capitano di Vascello Enrico Baroni) was sunk while covering the escape of {{ship|Italian destroyer|Zeffiro|1927|2}} and {{ship|Italian destroyer|Ostro|1928|2}} to Benghazi; 53 of the 225 crew and passengers were rescued, three of whom died of their wounds. The British and Australian cruisers expended a huge amount of ammunition and the Malta convoys had to be postponed until they had replenished from the {{nowrap|800 6-inch shells}} in reserve. Convoy AS 1 from Turkey arrived safely by 3 July.

Background

Italian belligerence

Italian supply shipments to Libia Italiana were landed at the ports of Tripoli ({{convert|2000|LT|t|0|abbr=on}} per day), Benghazi ({{convert|1000|LT|t|0|abbr=on}} per day) and Tobruk (fewer than ({{convert|1000|LT|t|0|abbr=on}} per day) with some deliveries possible to Derna and Bardia. Once landed, supplied and men had to be moved by lorry or small coastal craft. In late 1939, assuming overwhelming Anglo-French naval superiority, Marshal Pietro Badoglio, the Chief of Staff of the Italian armed forces (Comando Supremo Italiano), established a policy of maintaining internal security and to have supplied sufficient for a year.{{sfn|O'Hara|2009|p=48}} On 9 April, Badoglio met the three service chiefs, announced the

and ordered that the Regio Esercito (Royal Army) was to remain on the defensive as the Regia Marina and the Regia Aeronautica (Italian Royal Air Force) conducted offensive operations. On 30 May, Badoglio ordered the service chiefs to be ready for hostilities by 5 June.{{sfn|Bragadin|1957|pp=6–7, 15}} Italian war aims were to fight parallel with Germany, to dominate the Balkans, establish a land route to Africa Orientale Italiana (Italian East Africa) and assure access to Spain and the Black Sea.{{sfn|O'Hara|2009|p=47}}

Italian sea communications

On 11 April, the naval chief of staff, Admiral Domenico Cavagnari reported his doubts about the possibility of offensive action against opponents which could replace losses far quicker than Italy. Going to war with a defensive strategy was unprecedented and at the end of the war, Italy might have no territorial gains, no navy and no air force. The navy planned to keep its forces concentrated to generate maximum firepower, which precluded the protection of merchant shipping except on rare occasions; the French to the west and British to the east meant that convoying ships from Italy to Libya would be impossible. Mussolini saw off such doubts by predicting a war of three months' duration, when Libya had six months' supplies.{{sfn|Bragadin|1957|pp=6–7}}

Only on 10 June did Benito Mussolini direct that the military forces in Libia Italiana be reinforced for offensive operations and that the Regia Marina (Italian Royal Navy) was to protect the supply routes in the central Mediterranean.{{sfn|O'Hara|2009|p=48}} On 13 June, the first request arrived from Libya for the dispatch of "indispensable" supplies.{{sfn|Bragadin|1957|p=7}} In 1940, the Regia Marina had two modernised battleships and 19 cruisers to challenge the British and French Mediterranean fleets of three aircraft carriers, eleven battleships and 23 cruisers, a superiority of 4:1 in tonnage, which could be reinforced from outside the Mediterranean at will. The British ships were based at Gibraltar and Alexandria, with no ships based at Malta and the French at Toulon and Bizerte, the main Italian bases being Naples and Taranto, with small forces based in Sicilian ports. The Italian forces could unite by sailing through the Strait of Messina but the narrows were an obvious place for an ambush.{{sfn|Bragadin|1957|pp=7–8}}

Air power

The Regio Marina had advocated for the retention of a naval air arm after the First World War but after the creation of the Regia Aeronautica in 1923, lost control of naval aviation. The proponents of land-based air power disdained the naval preference for aircraft carriers and specialist aircraft, in favour of land-based aircraft fulfilling all of the requirements of maritime aviation, apart from an acceptance of the need for reconnaissance by "Aviation for the Navy" in which the navy had operational control and sent observers aloft. The Regia Aeronautica followed the theory of independent air operations "according to its own rules" and paid insufficient attention to the needs of the Regio Marina. Promising experiments with air-launched torpedoes from 1918 to 1922 were stifled by the new independent air force and even after the example of the British Fleet Air Arm experiments with torpedo-bombers, attempts by the Regio Marina in 1938 to gain control of a naval torpedo-bomber force failed.{{sfn|Bragadin|1957|pp=9–11}}

Prelude

Italian naval operations

On 10 June 1940, Italy declared war on Britain and France. Badoglio expected a British advance into Cyrenaica (eastern Libya) led by armoured forces. On 11 June, the 3rd and 7th Cruiser divisions conducted an abortive patrol in the Strait of Sicily; next morning, two British cruisers were spotted south of Crete heading west and the 3rd Cruiser Division and two destroyer squadrons were sent to patrol the route to Malta. The 1st and 8th Cruiser squadrons patrolled the Ionian Sea and two destroyer squadrons sailed between Sicily and Malta. On 12 June, an Italian Giovanni Berta-class Naval trawler was sunk off Tobruk by two British cruisers and four destroyers; the Italian submarine Alpino Attilio Bagnolini sank {{HMS |Calypso|D61|6}} south of Crete. From 11 June to 16 August, the specialist Orata Group dredged up the seven British cables from the seabed around Malta and took away thousands of yards of cable to prevent them from being reconnected.{{sfn|Bragadin|1957|pp=16–17}}

Italian supply operations

The difficulty of escorting merchant ships to Tobruk led to a decision to use warships and submarines. On 19 June, the submarine Zoea sailed for Tobruk carrying ammunition and the next day, a destroyer squadron led by Artigliere departed Augusta for Benghazi, carrying troops and anti-tank guns. On 25 June a convoy with escorts left Naples for Tripoli with {{nowrap|1,727 troops}} and supplies; the submarine Bragadin departed for Libya with equipment for the airfield at Tobruk.{{sfn|Bragadin|1957|pp=7, 20}} The Italian Turbine-class destroyers of the 2nd Destroyer Squadron, {{ship|Italian destroyer|Espero|1927|2}} (flagship, Capitano di Vascello Enrico Baroni), {{ship|Italian destroyer|Zeffiro|1927|2}} and {{ship|Italian destroyer|Ostro|1928|2}} were chosen to transport anti-tank units, for their high speed [{{convert|36|kn|mph km/h|lk=in|abbr=on}}] and loading capacity.{{sfn|Bragadin|1957|p=20}}{{efn|In 2009, O'Hara wrote that they were anti-aircraft units with 120 men, ten Breda Model 35 20 mm anti-aircraft guns and 450,000 rounds of ammunition.{{sfn|O'Hara|2009|p=49}}}} Two smaller First World War-era escort vessels, Pilo and Giuseppe Missori with 52 troops and additional supplies, departed Taranto independently for Tobruk some hours later.{{sfn|Bragadin|1957|p=20}}{{sfn|O'Hara|2009|p=49}}

Operation MA 3

On 27 June, five destroyers were to sail from Alexandria on an anti-submarine sweep near th Ionian island of Kythira and them sail on to Malta to form the close escort for convoys MF 1 and MS 2 to Alexandria. Intelligence about Italian submarines led to the sweep being diverted through the Kasos Strait east of Crete, then north of the island, thence past Kythira to Malta.{{sfn|Playfair|1959|p=148}} Short Sunderland flying boats of 201 Group RAF, based in Malta, were to co-operate with the naval operations in the Ionian Sea.{{sfn|Gill|1957|p=164}} On the Italian declaration of war, the passenger liner El Nil, en route for Egypt from Marseilles, Knight of Malta and interned Italian ship Rodi were in Malta and in Operation {{nowrap|MA 3}} these ships formed the fast convoy {{nowrap|MF 1}} [{{convert|13|kn|mph km/h|0|abbr=on}}]. Five slower ships, Zeeland, Kirkland, Masirah, Novasli and Tweed carrying naval stores for Alexandria, formed the slow convoy {{nowrap|MS 1}} [{{convert|9|kn|mph km/h|0|abbr=on}}] were to depart from Malta for Alexandria. {{nowrap|MF 1}} carried civilians being evacuated from Malta and all of the Mediterranean Fleet was to sortie to protect them in Operation {{nowrap|MA 5}}. Convoy AS1, with seven ships, was to sail from the Dardanelles to Egypt, with four ships joining from Salonika, Piraeus and Smyrna (İzmir), escorted by the light cruisers {{HMS|Capetown|D88|6}} and {{HMS|Caledon|D53|2}} of the 3rd Cruiser Squadron and the destroyers {{HMS|Garland|H37|6}}, {{HMS|Nubian|F36|2}}, {{HMS|Mohawk|F31|2}} and {{HMAS|Vampire|D68|2}}, due to depart from Cape Helles early on 28 June. {{sfn|Woodman|2003|p=43}}{{sfn|Gill|1957|p=163}}

The timing of the departures was arranged so that on 30 June the three convoys would be at Position K (35°N, 22°E), south of Cape Matapan, about halfway between Malta and Alexandria.{{sfn|Gill|1957|p=163}} Five cruisers of the 7th Cruiser Squadron (also known as Force C, Vice-Admiral John Tovey) with the 1st Cruiser Division, the Leander class cruisers (eight 6-inch guns) {{HMS|Orion|85|6}} (flagship), {{HMS|Neptune|20|2}}, {{HMAS|Sydney|1934|6}} and the 2nd Cruiser Division, the Town (Gloucester) class cruisers (twelve 6-inch guns) {{HMS|Liverpool|C11|2}} and {{HMS|Gloucester|C62|2}}, were to sail west of Crete near Position K.{{sfn|Gill|1957|p=163}}{{sfn|Playfair|1959|p=148}}{{sfn|Woodman|2000|p=42}} The 1st Battle Squadron (Rear-Admiral Henry Pridham-Wippell) with {{HMS|Royal Sovereign|05|6}} {{HMS|Ramillies|07|2}}, the aircraft carrier {{HMS|Eagle|1918|6}} and the 2nd Destroyer Flotilla, were to be south-west of Crete also near Position K, ready to intervene according to circumstances.{{sfn|Gill|1957|p=163}}{{sfn|Playfair|1959|p=148}} At {{nowrap|6:00 p.m.}} on 26 June, Caledon, Garland and Vampire sailed from Alexandria to rendezvous with Capetown, Nubian and Mohawk the next day while heading for the Dardanelles. A dawn on 27 June, five ships of the 2nd Destroyer Flotilla departed Alexandria and at {{nowrap|11:00 a.m.,}} the 7th Cruiser Squadron left for Position K.{{sfn|Gill|1957|pp=163–164, 166–167}}

27 June

As the sun set, the 2nd Destroyer Flotilla of Voyager, Dainty, Decoy, Defender and Ilex were {{convert|200|nmi|mi km|0|abbr=on}} north of Alexandria. At {{nowrap|6:28 p.m.}} while {{convert|100|nmi|mi km|0|abbr=on}} south-east of Crete, the flotilla spotted a submarine, Console Generale Liuzzi, which quickly dived. Four of the destroyers made depth-charge attacks and after the fifth an oil slick was seen and trailed by Dainty. The submarine had been badly damaged by the depth charging and was eventually forced to the surface. After a hunt of ninety minutes the submarine was seen again at {{convert|2500|yd|m|abbr=on}} and two destroyers fired on the submarines until a white light was taken to indicate a surrender. Dainty moved closer and began to take on survivors, along with other destroyers which lowered boats to pick up the Italians who had taken to the water. According to one British source, three hours fifteen minutes lapsed before the last two men from the submarine were taken off and the boat sunk with depth charges.{{sfn|Gill|1957|pp=166–167}} According to Italian sources, Liuzzi was scuttled by its own crew; ten men from the submarine's crew were killed in the engagement, including her commanding officer, Lieutenant Commander Lorenzo Bezzi, who after overseeing the evacuation of his crew went back inside the submarine and went down with it.^[1][2]

Battle

On 28 June, the Italian destroyers were spotted at {{nowrap|12:10 p.m.}} by a 228 Squadron Sunderland (L.5806) from Malta, about {{convert|50|nmi|mi km|0|abbr=on}} west of Zakynthos in the Ionian Sea, to the west of Greece and about {{convert|150|nmi|mi km|0|abbr=on}} from Position K.{{sfn|Playfair|1959|p=149}} No course was given by the Sunderland crew and the Italian ships were thought to be heading for Kythira; at {{nowrap|4:10 p.m.}} the 7th Cruiser squadron turned north to intercept the Italian ships. At {{nowrap|4:40 p.m.}} a sighting by Sunderland (L.5803) had them still heading south, about {{convert|35|nmi|mi km|0|abbr=on}} from Orion. Tovey ordered a turn to the south-west and an increase in speed to {{convert|25|kn|mph km/h|0|abbr=on}}. The cruisers sailed on a course of 180°, the 1st Cruiser Division, Orion, Neptune and Sydney to overhaul the Italians to starboard and the 2nd Cruiser Division, about {{convert|5|nmi|mi km|0|abbr=on}} apart from Liverpool and Manchester to overtake them to port.{{sfn|Gill|1957|p=164}}

The Italian destroyers were steaming south-east at high speed when they were spotted by Liverpool at {{nowrap|6:30 p.m.,}} about {{convert|100|nmi|mi km|abbr=on}} north of Tobruk; the cruiser commenced firing three minutes later at {{convert|18,000|yd|nmi mi km|abbr=on}}. The Italian ships had the notional speed to outrun the cruisers but their age, heavy loads and the sea state meant that the British ships slowly caught up.{{sfn|Greene|Massignani|2002|p=63}} The Italians had been taken by surprise and could not launch torpedoes because of their deck cargoes but they were difficult to hit as they made smoke, darkness gathered and the ships sailed towards the afterglow of the sun. At {{nowrap|7:05 p.m.}} Neptune reported torpedoes and the British ships changed course to comb the spread. The 2nd Cruiser Division concentrated on Espero and by {{nowrap|7:20 p.m.}} had closed the range to {{convert|14000|yd|nmi mi km|0|abbr=on}} and the 1st Division turned 50° to starboard to bring all their turrets to bear ("opening 'A' arcs") but Espero was not hit until the fifteenth salvo.{{sfn|Greene|Massignani|2002|p=63}}{{sfn|Gill|1957|p=165}} Baroni realised that his faster ships were doomed and decided to sacrifice Espero to enable the other two to escape, laid smoke and manoeuvred evasively as Zeffiro and Ostro raced south-west.{{sfn|Miller|1995|p=113}} At {{nowrap|8:00 p.m.}} Espero was hit and brought to a stop.{{sfn|Gill|1957|p=165}}

As night was falling and short of ammunition, Tovey abandoned the chase ten minutes later and changed course for Malta. Tovey ordered Sydney to finish off Espero and when at {{convert|6000|yd|nmi mi km|0|abbr=on}} received two shells from Espero and replied with four salvoes, scoring hits. Espero began to burn from the bow to midships and at {{nowrap|8:35 p.m.,}} Sydney closed to {{convert|2000|yd|m|0|abbr=on}} astern of the destroyer. Men jumped from the burning ship and there was an explosion near the bridge. At {{nowrap|8:40 p.m.,}} with a list of almost 90°, Espero sank at 35° 18' N; 20° 8' E. Sydney lowered both of its boats to rescue survivors and used Jacob's ladders and Bosun's chairs to bring them aboard. The glare from Espero before it sank and the presence of Italian submarines led to the rescue effort being ended at {{nowrap|10:19 p.m.}} when all 47 survivors in sight had been collected. before Sydney sailed away, one of the cutters with oars, sails, foodstuffs, water and rifles was left behind and with a signal projector illuminated so that remaining survivors could board it. Three of the survivors died before the ship reached Alexandria and six others were found alive on a raft by the Italian submarine Topazio fourteen days later.{{sfn|Greene|Massignani|2002|pp=63–65}}{{sfn|Sierra|1976|p=62}}{{sfn|Gill|1957|p=165}}{{sfn|O'Hara|2009|p=34}}

Aftermath

The engagement had lasted for about 130 minutes and the 7th Cruiser Squadron fired about 5,000 shells. An Italian {{convert|4.7|in|mm|abbr=on}} shell hit Liverpool {{convert|3|ft|m|abbr=on}} above the waterline but caused little damage.{{sfn|Greene|Massignani|1998|p=65}} Some of the prisoners on Sydney disclosed the purpose of the operation, that Espero had a company of 225 men and passengers embarked and that Baroni had been killed in the explosion near the bridge. Other survivors (including two officers), later questioned by an Italian enquiry commission about the loss of Espero, instead stated that Baroni had survived the explosion with only minor wounds, but had decided to go down with his ship.^[3] The ammunition consumption of the British cruisers exacerbated a shortage of ammunition at Alexandria, where only {{nowrap|800 6-inch}} shells were in stock. The Battle of the Espero Convoy demonstrated that a daylight naval action at long range was likely to be indecisive and wasteful of ammunition.{{sfn|Gill|1957|pp=165–166}}

The 2nd Cruiser Division was so short of ammunition that it returned to Alexandria and the Malta convoys were postponed. The 1st Cruiser Division reached Alexandria on 1 July, having also been ineffectually bombed. Convoy {{nowrap|AS 1}} from the Aegean was attacked from 29 June to 1 July by Italian aircraft based in the Dodecanese Islands but reached Alexandria and Port Said undamaged on 2 and 3 July.{{sfn|Gill|1957|pp=165–166}} In 1998, Green and Massignani wrote that had Italian aircraft spotted the Allied cruisers before they came within range, all three destroyers could have escaped.{{sfn|Greene|Massignani|1998|p=65}} Baroni was posthumously awarded the Medaglia d´oro al valor militare.{{sfn|Greene|Massignani|1998|p=65}} The lack of ammunition and the danger of Italian submarines led to the two Malta convoy sailings being postponed for two weeks, followed by Operation {{nowrap|MF 5,}} culminating in the Battle of Punta Stilo (9 July 1940).{{sfn|Woodman|2003|pp=43–52}}

Subsequent operations

At dawn on 29 June, the 2nd Destroyer Flotilla was {{convert|160|nmi|mi km|0|abbr=on}} west of Crete when the submarine Uebi Scebeli was caught on the surface. The submarine dived and was depth charged by three of the destroyers which forced Uebi Scebeli to the surface, where survivors were rescued. Dainty sank the submarine with gunfire at {{nowrap|8:20 am.;}} the destroyers made for Alexandria, arriving at about {{nowrap|7:00 p.m.}} on 30 June. Information was gleaned from the prisoners, of a submarine patrol line between Crete and the African coast; two destroyers were despatched from Alexandria on an anti-submarine sortie near Derna, detected a submerged submarine on 1 July and claimed its sinking, although this was disallowed when the ships returned on 2 July.{{sfn|Gill|1957|pp=167–168}} Zeffiro and Ostro had reached Benghazi on 29 June and arrived at Tobruk shortly after; two-thirds of the convoy had survived.{{sfn|O'Hara|2009|p=34}} The smaller Pilo and Missori also reached Libya after being diverted to the port of Tripoli.{{sfn|Colombo|2016|nopp=y}}

On 5 July, nine Fairey Swordfish torpedo-bombers of 813 Naval Air Squadron, Fleet Air Arm flew from Sidi Barrani near the Egypt–Libya frontier, to attack the ships in Tobruk harbour. Twelve fighters of 33 Squadron covered the Swordfish and 211 Squadron attacked the airfield, damaged eight Fiat CR.42 fighters and flew reconnaissance sorties. The Swordfish dropped seven torpedoes in the harbour, sank Zeffiro and damaged the destroyer Euro; the merchantmen Manzoni and Serenitas were also sunk and the liner Liguria was damaged. On the evening after the attack on Tobruk, 830 Naval Air Squadron from Malta bombed the airfield at Catania in Sicily. Capetown and Caledon of the 3rd Cruiser Squadron with four destroyers, bombarded the port Bardia from {{convert|9000|yd|mi km|abbr=on}} at dawn on 6 July and hit two ships, before making ready to assist the crews of any aircraft damaged on the Tobruk raid; Italian aircraft attacked the ships to no effect. {{sfn|Playfair|1959|p=150}} The guns of Zeffiro were salvaged from the harbour and sent to Bardia to augment the coastal defences.{{sfn|Greene|Massignani|2002|p=65}}
