Study Bilgepumps Taranto 80 part 1 of 3: Origins of the Flash in the Dark, a Dr. Alex Clarke video from 11 Nov 2020, with 40 time notes. Topics include Battle Of Taranto, Carrier Doctrine, Fleet Air Arm.
Time notes
- 1:30Taranto as the product of long preparationChapter
Taranto grew out of decades of naval-air thinking, planning, and practice before elderly biplanes struck the Italian fleet.
- 3:37American exercises demonstrate carrier attacks on fleet basesNotable Point
American Fleet Problems had already demonstrated how carriers operating ahead of battleships could surprise a defended base.
- 4:44QuestionWhy did the U.S. Navy practise carrier raids without recognising that another navy could do the same?AnswerQ&A
The explanation offered is that threat assessments and racist assumptions about Japanese capability prevented the exercises from changing expectations.
- 9:22Henderson creates a specialist carrier-planning staffChapter
Creating the Rear Admiral Aircraft Carriers post moved carrier aviation beyond battlecruiser-led scouting plans and into systematic studies of enemy fleet bases.
- 11:54Peacetime port photographs retain intelligence valueNotable Point
Old photographs could remain useful because the deep berths and heavy facilities needed by capital ships changed slowly.
- 13:22The Abyssinian Crisis makes a Taranto strike operationalChapter
Near-war conditions in 1935 turned accumulated base studies into a first-strike option, which Pound and Lister revived during the next crisis.
- 16:07Glorious develops a night torpedo plan that Pound rejectsNotable Point
Night flying, torpedoes and flares formed the attack concept, but Pound considered the projected losses unacceptable.
- 17:23Pound's close-passing drill risks Warspite and ArethusaNotable Point
Pound ordered Arethusa back toward Warspite on a close-passing drill that sent water over the battleship.
- 18:28QuestionWhy did Pound accept dangerous manoeuvres with valuable ships but reject a night air raid as too risky?AnswerQ&A
One suggested explanation is the scarcity of aircraft and specially trained night-flying crews, whose loss could leave an otherwise serviceable carrier without an air group.
- 20:15Caspar John tests procurement against night-flying needsNotable Point
A 1938 British mission to the United States judged rugged American aircraft against the Fleet Air Arm's requirements for safe, long-range night operations at sea.
- 23:26The uncertain value of prewar anti-aircraft estimatesNotable Point
Overconfidence in anti-aircraft fire may have inflated expected raid losses, while peacetime tests struggled to reproduce combat conditions.
- 28:50Taranto's place in Mediterranean force balanceChapter
The counterargument for Taranto is that French reinforcements would still leave Allied ships tied together against the Italian battle fleet.
- 33:06French participation and a hypothetical larger carrier strikeNotable Point
One counterfactual combines British carriers at Taranto and assigns Béarn a separate diversion against Genoa.
- 35:46Eagle's fuel leaks strain an ageing carrierNotable Point
Bombing damage and heavy service aggravated Eagle's fuel system even as an improvised Sea Gladiator group increased her usefulness.
- 39:19Why Illustrious changed Cunningham's optionsNotable Point
Illustrious brought a mixed air group and Lister's experience, giving Cunningham the means to revive the Taranto plan.
- 41:20The torpedo solutions that made Taranto possibleChapter
Taranto depended on combining an advanced duplex pistol with a simple cable arrangement that kept air-dropped torpedoes shallow.
- 46:40A hangar fire delays the operationNotable Point
A spark in Illustrious's hangar disrupted the Trafalgar Day plan and forced a demanding restoration of salt-water-soaked aircraft.
- 50:09The hangar fire revives an unadopted rubber-hammer recommendationNotable Point
Suitable hammers were already in storage when the fire forced the fleet to adopt an earlier safety recommendation.
- 51:27An internal fuel tank displaces the Swordfish observerNotable Point
The torpedo load forced extra fuel into the observer's seat, leaving the observer to work the rear gun beside a leaking tank.
- 54:04Naval air engineers restore Illustrious's damaged air groupNotable Point
Engineers restored the damaged aircraft while supplying technical experience directly to the Royal Navy's command structure.
- 56:18Cunningham accepts the risk after Ark Royal attacks DunkerqueNotable Point
Ark Royal's recent Swordfish attack on Dunkerque helped convince Cunningham that a costly Taranto strike could still be operationally necessary.
- 57:18Pollock bypasses an intelligence-sharing barrierChapter
Lieutenant David Pollock covertly copied RAF reconnaissance photographs so Illustrious's planners could study Taranto's ships and barrage balloons directly.
- 1:01:42QuestionWhy would the RAF withhold reconnaissance photographs from the Royal Navy when both services were fighting the same enemy?AnswerQ&A
Interwar bomber-versus-battleship arguments and resentment over the Fleet Air Arm had hardened into senior-level rivalry that could override practical cooperation.
- 1:03:29Caspar John's flying experience challenges Harris's dismissalNotable Point
A Weir Mission anecdote credits Caspar John with greater relevant flying experience than Harris, despite Harris's dismissal of his naval colleague.
- 1:05:15Harbour geography and incomplete torpedo nets shape the attackChapter
Taranto's deep-water anchorage, inner lagoon, fuel facilities, storm-damaged balloons, and partial net barrier defined both the targets and the available attack lanes.
- 1:08:34The uncertain source of Taranto's net-depth intelligenceNotable Point
The net depth was known to the planners, but the proposed explanation involving a prewar visitor remains unverified.
- 1:10:02Sound detectors could warn Taranto without preventing surpriseNotable Point
Italy lacked radar but fielded acoustic warning posts; the real vulnerability was confidence that reconnaissance would reveal a British approach in time.
- 1:12:46Readiness and complex mounts weaken Italian anti-aircraft fireChapter
Taranto had dense gun coverage and partially manned weapons around the clock, but complicated stabilised mounts and accumulated fatigue made readiness uneven.
- 1:18:51A crowded anchorage restricts Italian fields of fireNotable Point
Taranto's irregularly spaced battleships created dangerous firing arcs in which missed shots could strike another ship or the town.
- 1:21:01Operation MB8 hides the real objectiveChapter
Cunningham used overlapping convoys and fleet movements across the Mediterranean to make Taranto only one possibility among many.
- 1:22:45Doctrinal rivalry complicates secrecy before TarantoNotable Point
Concern that overflights or independent bombing would expose Taranto brings out how sincere doctrinal convictions could intensify service rivalry.
- 1:24:30Missing scouts leave a misleading intelligence pictureNotable Point
Reports from surviving scouts could draw attention away from the waters where carrier fighters prevented reports from getting through.
- 1:26:24Eagle reinforces Illustrious despite staying in portNotable Point
Eagle's leaking fuel system kept her out of Force A, but she transferred aircraft and crews that directly strengthened Illustrious's strike and fighter cover.
- 1:29:27Fulmars transfer through Malta to reinforce IllustriousNotable Point
A three-aircraft transfer through Malta increased Illustrious's fighter strength and demonstrated the navigational value of a two-seat fighter.
- 1:31:21Deck parks and outriggers make room for extra fightersNotable Point
Parking aircraft on deck and partly over the side let British carriers accommodate fighters beyond their hangar capacity.
- 1:32:35Swordfish attack the reconnaissance aircraft that could find the fleetNotable Point
A deliberate strike on reconnaissance hangars helped conceal the British movements and showed the Swordfish's range of useful roles.
- 1:34:45The reinforcement passage provides a convincing diversionNotable Point
A risky night passage through the Sicilian Channel delivered major reinforcements and gave Italian commanders a convincing explanation for the wider British activity.
- 1:36:52Carrier fighters create a reconnaissance blind spot east of MaltaNotable Point
Fulmars and Sea Gladiators destroyed Italian scouts around Force A, leaving commanders aware of British movement but unable to locate the most dangerous force.
- 1:38:33Armoured carrier design trades air-group size for survivabilityNotable Point
Two lost Swordfish exposed Illustrious's limited replacement margin and the survivability trade-off built into an armoured carrier.
- 1:41:18A few Fulmars disrupt fifteen SM.79 bombersNotable Point
Radar warning let two or three Fulmars break up a fifteen-bomber attack before it reached the fleet, demonstrating the fighter's value in its 1940 role.
