Update 03-08-2019 – added further info on who attacked and ultimately sank SS Alfredo Oriani off Cape Matapan
Added German Navy AA Report Information – 22 September 2018
The summer of 1941 was primarily spent trying to build up the Axis forces in North Africa to prepare for the assault on Tobruk and the subsequent invasion of Egypt. While the supply route overall was delivering, with the vast majority of supplies reaching their destination, losses were suffered on a regular basis. I have previously written about the quite harrowing experience of the Malta Blenheim IVs of Nos. 105 and 107 Squadrons engaging the Axis supplies at this link.

Nevertheless, while the loss rate on daytime shipping strikes was brutal, the reward was high, when a fully laden merchant with vital supplies could be sent to the depths of the Mediterranean. This happened on 11-13 September 1941, when the Malta strike forces had a good outing against the 44th convoy with Italian and German supplies, known to the Italians as the TEMBIEN convoy, and also sank the single runner SS Alfredo Oriani. While the loss of three merchant vessels in two days was a remarkable success to the Royal Air Force, it came at a price.
The article below also sets the historic record straight, by providing clarity on who sank what, and addressing the claims made by the Fleet Air Arm Swordfish operating out of Malta.
Air/Sea Battle on the North Africa Route 11-13 September 1941
The period saw heavy anti-shipping operations by the Malta-based British aircraft, covering the 11-13 September, with substantial losses on both sides.
The 12th of September 1941 day saw the heaviest anti-shipping operations, with a total of 22-29 aircraft operating out of Malta according to the Malta War Diary, 7x Wellington of No. 38 Squadron in a night attack, 8x Blenheim of No. 105 Squadron in the afternoon, and 7x Swordfish of No. 830 Squadron F.A.A. operating possibly twice during the night and the afternoon.
Losses were heavy, with 3x Blenheims lost, those of S/Ldr Charney D.F.C. with Observer Sgt. Porteous and Wireless Op./Air Gunner Sgt. Harris, Sgt. Mortimer with Observer Sgt. Reid and Wireless Op./Air Gunner Sgt. Owen, and Sgt. Brandwood. The latter and his crew were rescued by HM/Sub Utmost on 14 September, and the former two crews were all killed. Another Blenheim belly-landed on Malta due to damage from the naval anti-air fire.
Two ships were sunk, SS Caffaro by No.105 and SS Nicoló Odero by No.38 Squadron, both out of the Tembien convoy. Furthermore, on the 13th the Italian 3,059t steamer SS Alfredo Oriani, a merchant with an identical name to the escort leader of the Tembien convoy, sank halfway to Benghasi following an air attack while on the way to Benghasi, from Patras, on 11 September, probably again by No. 105 Squadron. Thus, the R.A.F. sent a total of over 15,500 tons of shipping carrying thousands of tons of supplies and hundreds of vehicles to the bottom of the sea.
Based on information from Lorenzo Colombo, who runs the excellent Con la Pelle appesa a un Chiodo blog detailing all Italian vessel losses, the butcher’s bill for the three days was amounted to 26 on the Axis side, to which need to be added six R.A.F. crew members in two of the lost Blenheims and the German army officer who died of wounds in Tripoli, for a total of 33 killed:
- SS Caffaro carried 228 men, including 168 Germans; 224 survived and four were missing (two Italian crew members and two Germans)
- SS Nicolò Odero had 285 survivors, the victims were about twenty including 4 crew members (the other being troops and AA crews)
- SS Alfredo Oriani had 50 men aboard, two were missing and 48 survived.
There are substantial discrepancies between the British and the Italian accounts, which I am aiming to clear up below. A big gap is the lack of an operations record book for No.830 Squadron. I have inquired with the Fleet Air Arm Museum in Yeovilton, but to no avail. I will also add a bit more analysis on the issue of who sank SS Alfredo Oriani.
Official Accounts and Memories
The write up in the Malta war diary is below:
An Italian convoy of steamers TEMBIEN, CAFFARO, NIRVO, BAINSIZZA, NICOLO ODERO, and GUILA departed Naples on the 10th, escorted by destroyers ORIANI and FULMINE and torpedo boats PROCIONE, PEGASO, ORSA, and CIRCE from Trapani, and OERSEO which joined at 0600/13th.
Italian steamer CAFFARO (6476grt) was sunk by British Swordfish of 830 Squadron from Malta 105° northwest of Tripoli in 34-14N, 11-54E.
Italian steamer TEMBIEN (5584grt) was damaged by 830 Squadron attack.
Italian steamer NICOLO ODERO (6003grt) was damaged in the attack. She was sunk on the 14th by RAF bombing in 32-51N, 12-18E after the convoy arrived at Tripoli on the 13th.
One of the air crew of No 830 Squadron, Sub-Lt. Campbell describes the attack thus at this link:
12/13.9 – If my memory serves me right this was the night about which the Malta Daily Paper headlined as “Ducks and Drakes in the Med”. The Squadron took off at dusk to attack a large Convoy heavily escorted by Destroyers. We found the Convoy and attacked individualy, splitting it up completely. At least three ships were hit and Destroyers were racing about all over the place. We returned to base and my flight were sent out again to finish off the remaining ships. As we approached the scene of the previous engagement, I saw a Destroyer racing along at high speed. I decided to follow it to see if it would lead me to the remaining ships, this took some doing in a “Stringbag”, if there had been any wind against me I couldn’t have done it. After awhile I saw a large MV and attacked it. There was a bright flash and then it just blew up.
The above two accounts are severely flawed. Fortunately though on the British side, a fairly detailed account by No.105 Squadron has survived, in AIR27/826, the Operations Record Book (ORB) of No. 105 Squadron, and a less detailed account in the ORB of No. 38 Squadron.
First, the attack that I believe claimed SS Alfredo Oriani on 11 September, even though the timing of the attack reports in the British and Italian accounts diverges by a day, and the British pilots reported another merchant present. Nevertheless, the description of the attack and the location of it and the sinking are so close that I believe No.105 Squadron was responsible for her loss, following a check in the Nos. 11, 14, 55 and 107 Squadron Operations Record Books. This is confirmed by Shores, Cull, and Malizia in Malta: The Hurricane Years, which records that No. 105 Squadron under Smithers went out on 10 September (sic) to attack two vessels off the Greek coast, leaving one in what they believed a sinking condition, although this also utilises the squadron ORB transcribed below. We still need Italian records to be certain what happened and when.
The Malta Admiralty War Diary describes the attack thus:
Italian steamer ALFREDO ORIANI (3059grt) was sunk by British Blenheim bombers in 35-05N, 20-16E.
The steamer which had departed Petrasso on the 11th was escorted by torpedo boat CANTORE.
SS Alfredo Oriani in peacetime, from Wrecksite.eu
No. 105 Squadron ORB states that five Blenheim IV went out on a shipping sweep at 0645am on 11 September. The attacking aircraft returned at 1211pm, while two returned early at 0750am. Crews were S/Ldr Smithers with Sgts. Harford and Green, F/Lt. Duncan with Sgts. Smith and Lyndall, Sgt. Bendall, with Sgts. Hindle and Brown, Sgt. Mortimer, Sgt. Weston, with Sgts. Storey and Kindell.
Five crews were detailed for an offensive sweep of the Ionian Sea.
The aircraft departed in two waves, the first sighting two MERCHANT VESSELS and DESTROYER escort in position 35°33N. 20°35’E.
One aircraft – SQUADRON LEADER SMITHERS – attacked first dropping bombs from stern to bow and registered a hit amidships.
The other aircraft attacking the same ship claim one hit each but not confirmed.
The MERCHANT VESSEL when last see appeared to be settling in the water in a sinking condition.
The second wave – FLIGHT LIEUTENANT DUNCAN and SGT. MORTIMER – returned with engine trouble.
All aircraft landed safely at BASE.
In the Italian official history, her loss is described thus.
11 September 4am from Patras to Benghazi. Steamer A. Oriani. Escort Escort Destroyer Cantore then Altair (from 1700 hours on 13 September). Attacked and repeatedly hit by bombers at 1400 hours on 12 September, 60 nautical off Cape Matapan, sinks at 1800 hours on the 13th.
The position of SS Alfredo Oriani’s sinking is not 60nm, but over 100 nautical miles off Cape Matapan. (Map done by me using Google Maps)
The position is about 186nm out of Patrassos, or about 17 hours steaming at full speed. (Map done by me using Google Maps)
More puzzlingly, at the time of the attack, she would have steamed about 190nm. A solid 17 hours of steaming at 11knots, her top speed. Pretty much impossible in the ten hours since she left port according to the Italian OH. Furthermore, the timing of the No. 105 Squadron operations on that day and the attack timing do not line up. Nevertheless, there is no record of another Blenheim unit attacking a vessel in the Ionian Sea on 11 September 1941.
A strong possibility would be that the Italian OH is wrong here. It is clearly wrong giving the position of Oriani being attacked as 60nm off Cape Matapan (the actual position of the attack is almost on a straight line from Patras to Benghazi, while 60nm would be too far east), and is also wrong in giving the position of her sinking as 80nm north of Benghazi. It is therefore not impossible that the time or date of her departure and the actual time of the attack are also wrong. For example, an average speed of 7 knots would have put her almost straight into the attack position around 0800 hours on the morning of the 11th, had she departed Patras on 10 September at 0400 hours in the morning, instead of the 11 September. The location is about an hour and a halfs’ flying time in a Blenheim IV from Malta. Given that No. 105’s Blenheim’s left at 0645 hours, they could have been there at 0815 hours.

SS Alfredo Oriani sank two days later on 13 September at 35°05’N 20°16’E, about 80 nautical miles north of Benghazi according to the Italian official history, although this position is more like 180 miles north of Benghazi. That position is 19 nautical miles west and 28 nautical miles south of the attack position given in the No. 105 ORB, indicating that the vessel drifted about 33 nautical miles, or a speed of less than a knot after the attack. It is also physically impossible for Oriani to have made it to the position of the attack as given by the Italian official history, if her departure date is correct even if steaming at maximum speed of 11.5 knots. Patras is about 14 hours of steaming as the crow flies, given Oriani’s speed, from the location of the attack. My guess is that the Italian official history is not correct when it comes to the time/day of her departure.
This day was the big one. The first to attack were No. 830 Squadron with their Swordfish, without success.
In the afternoon of the 12th, eight Blenheim IV were despatched by No. 105 Squadron. This time, it did not go so well for them. The crews were S/Ld Smithers with Sgts. Harbord and Fisher, Sd/Ld. Charney with Sgts. Portous and Harris, F/Lt. Ballands, F/O Greenhill, Sgt. Brandwood with Sgts. Miller and See, Sgt. Weston with Sgts. Storey and Kindell, Sgt. Bendall with Sgts. Hindle and Brown, and Sgt. Mortimer with Sgt. Reid and F/O Owen.
Eight crews were detailed to attack a CONVOY attacked by SWORDFISH aircraft the previous night.
The CONVOY was estimated to consist of six MERCHANT VESSELS of 6000 – 12000 tons and six escorting DESTROYERS and was attacked at 1415 hours.
Two aircraft – SQUADRON LEADER SMITHERS and SGT. WESTON – claimed two hits each with 250lb and 500lb bombs respectively. This MERCHANT VESSEL was left a mass of flames and a later reconnaissance report indicated that it had probably sunk.
One aircraft – SGT. BENDALL – attacked a 10000 ton MERCHANT VESSEL and scored two direct hits with 500lb bombs causing a large fire.
Two aircraft – FLIGHT LIEUTENANT BALLANDS and FLYING OFFICER GREENHILL – did not bomb as their approach was obstructed by other aircraft. Anti-aircraft opposition was intense from the DESTROYERS and three MACCHI 200 FIGHTERS and three C.R.42’s were reported diving out of the clouds though no attacks were witnessed.
One aircraft – SQUADRON LEADER CHARNEY – was shot down in flames near the CONVOY with little hope of survivors. One aircraft – SGT. MORTIMER – failed to return and nothing further was heard of the crew.
Another aircraft – SGT. BRANDWOOD – came down into the sea about 12 miles from the convoy but the crew were rescued the next day by a submarine.
Five aircraft landed safely at BASE, one of these – SGT. BENDALL – was forced to execute a belly landing owing to damage to the hydraulic system. The observer – SGT. HINDLE – was slightly wounded.
The British accounts are incorrect in several aspects, and need to be read with the Italian account of the battle. Fortunately, the Italian official history La Difesa del Trafico Vol. I has an account of this convoy battle as well, which would lead to the total loss of two of the five steamers with their important cargo. For example, while there were six merchants and six escorts, none of the merchants came in at 12,000 tons.
An adventurous voyage, albeit marked by painful losses, was that of the TEMBIEN convoy, which left Naples the morning of the 10th for Tripoli. This was the second convoy of cargo vessels bound for Libya in the month of September and, since it was composed of slower vessels, it had orders to follow the route of the Marettimo Channel of Sicily to the Kerkennah Banks, the route called the Ponente .
The steamers TEMBIEN, CAFFARO, NIRVO, NICOLO’ ODERO and BAINSIZZA were part of the convoy; the escort consisted of the destroyers ORIANI (Convoy Leader Commander Chinigò) and FULMINE and the torpedo boats PROCIONE, PEGASO, and ORSA, with which the torpedo boat CIRCE united in the Sicily Channel.
During the night 11/12 November the convoy was discovered by a nighttime reconnaissance plane south of Pantelleria. Thus at 03.10 hours of the 12th an attack by torpedo bombers followed, avoided by the maneuvering of the convoy, a smoke screen, and the anti-air reaction of various units.
The following morning the formation navigated without incident or alarm along the Kerkennah following diverse routes. But at 14.00 hours, while under escort of Italian planes, it was again attacked by airplanes, this time by bombers. This was the second air attack during the crossing. Not the last one however, since two more times, between Zuara and Tripoli, during the nights of the 12th and 13th, the convoy was attacked from the air.

On the daytime attack of the 12th, and the two following nights, the Escort Commander, Commander Chinigo, referred thus in his report:
14.00 hours – Eight enemy planes are sighted, coming from the west at low height towards the formation. The escorting units and the steamers open targeted and barrage fire. Numerous water columns are seen close to the escort units and the steamers. Three of the attacking planes hit by the anti-aircraft fire crash in flames.
14.10 hours – The CAFFARO, hit by a bomb, takes fire. I am ordering CIRCE and ORSA and then FULMINE to come to the aid of the unfortunate steamer. I send the standard signal of having been discovered.
15.00 hours – Continued observation of flames from the fire in the direction of CAFFARO, and more and more explosions can be heard.
15.55 hours – I inform Supermarina and Marina Tripoli of the air attack with the reservation that further information cannot be provided yet.
16.05 hours – I observe a strong explosion in the direction of CAFFARO. Immediately after CIRCE signals that the steamer has sunk.
16.50 hours – CIRCE, FULMINE, ORSA report that they have on board 110, 35, and 79 shipwrecked, respectively. CIRCE and ORSA also that they have no-one particularly badly hurt.
18.40 hours – Notify Supermarina and Marina Tripoli of the sinking of CAFFARO and the number of shipwrecked rescued. Communicate furthermore that FULMINE is navigating for Tripoli with one severely wounded.
23.54 hours – At point C of the safe route to Tripoli. Steamers proceed in line astern.
It is worth noting that the German documentation on the downed Blenheims is somewhat more precise. German navy AA crews were on board of at least the steamer Nirvo. They reported that all three Blenheims were downed at 14.35 hours, one directly by the Kriegsmarine AA embarked on Nirvo, one by AA from a destroyer, with support from the Kriegsmarine AA on board Nirvo, and the other downed by AA weapons of embarked troops on Nirvo. Ammunition use was 23, 13, and 62 rounds of 2cm AA, respectively. The weather is described as clear and sunny, with medium visibility.

While the ORB of No. 38 Squadron places this attack on the 12th, I am certain it actually happened in the night 12/13 September, from 0340am to 0455am, seven Wellingtons of No. 38 Squadron bombed the convoy. They suffered no losses. Crews were led by Sgts. Robotham, Brine, Earl, Pottis, Secomb and Hawes, and F/Lt. Davis.
Target – Convoy – proceeding to Tripoli. Convoy was located 25 miles N.W. of Tripoli and was attacked from 03.40 to 04.55 hours.
Bombs dropped 24,500.lbs.
Results: four ships were hit, fires starting on two of them.
Opposition: light flack from escorting destroyers.
The timing of the attack fits exactly with the timing of the aircraft noise report by Tp Circe. The hits reported were then on SS Nicoló Odero. The earlier attack was almost certainly again a torpedo attack, with the standard attack pattern.
01.05 hours – Four or five airplanes are seen on a course of 240 degrees with landing lights illuminated. Issue the air alarm signal to all units.
01.20 hours – Numerous flares light up to the left of the formation. Order the escort units to make smoke. The units and the steamers fire targeted and barrage. A total of 18 flares are counted.
02.30 hours – The attack ceases and the formation is reordered, and normal navigation proceeds.
03.33 hours – Marina Tripoli informs me that the PERSEO leaves Zuara and will join the convoy to strengthen the escort. Further informs that at sunrise a MAS will be the pilot for the safe route.
03.45 hours – CIRCE signals aircraft noises to the rear.
03.55 hours – A flare light is seen on the right of the convoy. I issue the standard signal of having been discovered. Escort units and steamers open barrage fire. Smoke is made.
04.00 hours – An explosion on one of the steamers is observed.
04.04 hours – CIRCE signals that the steamer ODERO was hit.
04.24 hours – A bomb hits in our wake at about 100 meters from the stern. Fire is opened with the machine guns.
04.30 hours – CIRCE signals that there are men in the water and requests that another escort is sent. I order ORSA and PERSEO, which during the attack rejoined the formation, to get close to CIRCE and cooperate in the assistance of the hit steamer and to the rescue of the shipwrecked.
05.00 hours – The attack ceases and the formation is taken up again, and we proceed on the safe route.
05.05 hours – CIRCE signals that the ODERO has fire on board, but that she is not sinking, and requests sending a tug.
The steamer NICOLO’ ODERO, even though in flames, remains afloat for many hours, with the support of the torpedo boats ORSA, CIRCE, and PERSEO which, in the first instance, are engaged in saving the men embarked on the merchant.
Torpedo boat RN Perseo, lead of her sub-class of Spica torpedo boats.
In support of the steamer, the tugs PRONTA and PORTO PALO leave Tripoli at sunrise, seeking with any means to extinguish the fire which is still raging on the merchant. The PORTO PALO even goes alongside the ODERO, sending men to fight the fire.
Only when it is clear that the flames cannot be doused do the two tugs take the burning steamer in tow, first trying to reach Tripoli, and then to beach it on the coast. During the whole night, the two tugs and two motor trawlers, also coming from Tripoli, remain close to the steamer with the hope to ultimately save it, but during the afternoon of the 14th September a hold with ammunition blows up, causing the destruction of the NICOLO’ ODERO.
No. 38 Squadron then ‘visited’ Tripoli on the 13th, again I believe this was the night of 13/14, probably to attack during the unloading of the convoy. The report of Odero having been beached, which only happened on the 14th, is a give-away in this regard.
Numerous bombs on the harbour edge are reported and six Italian soldiers killed in a direct hit on their MG position near the lighthouse. Seven Wellingtons went out, with the crews of Flight Officer Pascall, Pilot Officer Ridgway, and Sgts. Cooper, Fell, McManus, and Nankivell. None were lost.
Target – Tripoli – shipping alongside Spanish Quay. Attack lasted from 03.00 to 04.35 hours.
Bombs dropped 27,500. lbs.
Bombs fell on or near the Quay.
Aircraft reported a large ship aground 30 miles W. of Tripoli. This M/V presumed to be one of those set on fire during previous night’s attack on convoy.
Opposition: effective smoke-screen. Heavy A.A. aimed at aircraft, not barrage fire. Light A.A. as usual. Eleven searchlights operated.
It is clear from the Italian account that the British accounts were severely mistaken about the impact of their attacks. No ships had been hit in the night attack by No. 830 Squadron on 11/12 September. In the afternoon attack by No. 105 Squadron, only one merchant had been hit, not two. The second attack by the Swordfish is not mentioned at all.
What is also interesting is that the Italian air escort is not mentioned by the Italian report.
Sub-Lt. Campbell of No. 830 Squadron seems to overstate the case of his attack somewhat regarding his hit on what must have been Caffaro. At this stage I am doubtful regarding his claim, and what could be surmised is that the explosion leading to the end of Caffaro was actually caused by a torpedo hit. But overall his story does not stack up, while the time of the Blenheim attack, the description by the escort commander, and the losses all seem to fit.
The official Italian history claims she was hit by a bomb, which appears the likely reason. The Italian report of eight attacking planes, of which three were shot down, is therefore to be considered an accurate account of the loss of Caffaro.
As for No. 105 Squadron, this was to be one of the last operations it flew in the Mediterranean. It suffered two more losses. Sgt. Bendall and crew on 17 September when attacking a small convoy, and Wing Commander Sciviers and his crew on 22 September, when his plane collided with that of Sgt. Williams during an attack on the barracks at Homs in Libya. The attack on the small convoy on 17 September is again well documented.
First the British side:
Three aircraft took off to attack one small MERCHANT VESSEL, one TUG and two SCHOONERS. One SCHOONER was left a mass of flames and the other was seen to blow up and disintegrate. One aircraft failed to return from this OPERATION. The crew were – SGT. BENDALL – Pilot: Sgt. HILL – Observer. SGT BROWN – W/OP/A.G.
PILOT OFFICER ROBINSON of No. 107 Squadron also proceeded on this operation and failed to return.
From the Italian side:
14 September 2200 hours from Trapani to Tripoli. Steamer Ascianghi, Steam Tug Mirabello del Parco with Minesweeper Pietrino in tow; Motor Schooner Filuccio. Escort Escort Destroyer Clio. At 1600 hours of 17 September, 15 miles north of Zuara, the convoy is attacked by bombers. Three are shot down and one of these crashes on Mv Filuccio, provoking a fire and her sinking. The Ascianghi rescues 10 out of 13 members of the crew. On the 18th at 0900 hours at Tripoli without Mv Filuccio.
The sections show again how easy it was to get things wrong.
In October No. 105 Squadron was withdrawn back to the UK, to convert to Mosquitos. It did maintain a Blenheim I as a ‘hack’ plane. No. 107 Squadron took over operations on Malta, with similarly tragic performance.
According to the German loading lists, Nicoló Odero did not carry any German supplies on this voyage. Caffaro however did. She went down with substantial numbers of vehicles, rations, and ammunition, losses that the German forces could ill afford, and that further delayed the build up to the attack on Tobruk, which in turn enabled the Allied forces to attack first. The full list of her German load is given below. She almost certainly also carried Italian cargo, but I have not been able to find the manifest for this. While Caffaro carried a substantial number of soldiers, primarily drivers for the vehicles of 7./Flak 25, Heeresfunkstelle XVIII and Stab Panzergruppe, most of these are likely to have been rescued, with 224 men being picked up.
 Should be MV Giulia. Orseo should be Perseo, a Spica class boat, the staple Regia Marina escort. Displacing 1,020 tons at full load, they were armed with 3x10cm guns, four 450mm torpedo tubes, and a reasonable set of AA and ASW weaponry, running 34 knots top speed.
 This was a powerful escort with substantial AA capabilities. Strangely, the report omits to mention the MV Giulia, which was definitely part of the convoy,.
 The Orianis were a class of four modern, large destroyers. An improved repeat of the Maestrale class, with 2,470t at full displacement, 4x120mm main guns and six torpedo tubes as main armament, and a claimed top speed of 38 knots. They carried improved anti-air guns compared to the Maestrales. Oriani survived the war and served in the French navy until 1954.
Commander Chinigò survived the war and after the war rose to the rank of Captain and commanded the Italian battleship Littorio, being her last captain.
 A Folgore class destroyer, an older ship, she was sunk less than two months later in the Duisburg/Beta convoy battle on 9 November 1941 with the loss of 141 men including her commander, Lt.Cdr. Mario Milano. The Folgores were not a lucky class, with all four ships lost during the war. They displaced 2,096 tons at full load, carried 4x120mm guns and six torpedo tubes as main armament, and had a claimed top speed of 38 knots. A repeat of the Freccia class they had less stability and range than the preceding class due to a reduction in their beam.
 Orsa-class torpedo boats, an enlarged version of the Spicas (see below). At 1,575 tons full displacement, they traded one 10cm gun for improved AA and ASW equipment, carrying also 4x 450mm torpedo tubes and only running at up to 28 knots. Pegaso claimed four Royal Navy submarines, which if confirmed would make her one of the top submarine hunters of the Regia Marina. There are however doubts over this record. Pegaso and Procione were scuttled at the armistice in September 1943, while Orsa survived the war and continued to serve until 1964.
 Circe was also a Spica-class boat. Circe destroyed four confirmed Royal Navy submarines during the war, making her one of the most successful sub-hunters of the Regia Marina.
 This are likely to have been the eight Blenheims of No. 105 Squadron out of Luqa, Malta, on their attack run.

 This was standard attacking practice for the torpedo bombers. The lead aircraft which carried radar instead of a torpedo would drop flares behind the convoy, to silhouette it, and enable the attacking planes to approach from the dark.
