Time notes
- 11:33British global commitments and the naval reversal in 1813Chapter
British commitments against Napoleon qualify Roosevelt's criticism of early naval performance, while reinforced squadrons and revised frigate orders explain the reversal in 1813.
- 17:30How the British blockade closed American commerceNotable Point
The blockade disrupted ordinary merchant trade while leaving narrow opportunities for fast privateers and exposing towns along navigable rivers.
- 19:13Roosevelt's twenty-ship argument for naval preparation before warNotable Point
A hypothetical fleet of twenty ships of the line connects the losses under blockade to Roosevelt's case for naval investment and training before war.
- 22:59QuestionWhy did the United States choose to fight the War of 1812?AnswerQ&A
In this interpretation, American leaders expected to seize Canada while France defeated Britain.
- 25:19QuestionDoes Theodore Roosevelt's naval history of the War of 1812 cover operations on the Great Lakes?AnswerQ&A
Yes. It covers the Great Lakes, takes particular interest in their commanders, and combines high-level history with close detail.
- 25:45Bad powder and a broken gun carriage doom Gunboat No. 121Notable Point
An isolated American gunboat loses its long gun during a British boat attack, after poor powder has already frustrated the flotilla's gunnery.
- 27:19Asp's survivors return after a British boarding attackNotable Point
Asp's surviving crew reboarded their burning gunboat after the British withdrew, although the claim that she was ready to fight again is questioned.
- 28:12Surveyor's defence earns the return of her commander's swordNotable Point
Surveyor's fifteen-man crew resisted a much larger boarding party fiercely enough for the victorious officer to return William Travis's sword.
- 29:16Alligator repels a night boat attack at the Stone RiverNotable Point
Alligator's small crew beat off British boats after dark and captured one of the attacking craft.
- 30:07QuestionHow quickly would a Clemson-class destroyer sink a 120-gun ship of the line such as L'Orient?AnswerQ&A
High-explosive ammunition is expected to destroy L'Orient very quickly; armour-piercing rounds might pass through its wooden hull with less destructive effect.
- 32:10QuestionWho would win between USS Gearing and HMS Victory without torpedoes, and how long would it take?AnswerQ&A
With high-explosive ammunition, Gearing could stay outside Victory's range and destroy her with a few hits, especially if it struck the powder.
- 33:39Modern Naval Strategy charts the battleship cost spiralChapter
A comparison of Victory, Alexandra, Camperdown, Lord Nelson, Dreadnought, and Nelson shows battleship costs rising faster than displacement.
- 37:49Why Modern Naval Strategy ties battleships to an enemy battle fleetNotable Point
The book relates the purpose of a battle fleet to opposing battleships and distinguishes capital-ship construction from the quicker expansion of smaller forces.
- 38:59Barham and Admiral Scheer test the case for smaller battleshipsNotable Point
Armour, machinery, hull length, and gun power complicate the claim that several smaller ships can replace a large battleship at equal cost.
- 41:28Reading Modern Naval Strategy as evidence of interwar thinkingNotable Point
A qualified recommendation treats the book as evidence of interwar naval thinking despite substantial disagreement with its conclusions.
- 44:28QuestionCould Admiral Scheer handle Scandinavian coastal battleships?AnswerQ&A
Possibly not if the coastal battleships were alert and ready to fire immediately.
- 46:17Serbia's alternatives when answering the July Crisis ultimatumChapter
Serbia faced a choice between outright rejection, acceptance followed by negotiation, and carefully qualified concessions.
- 49:57Serbia's reply denies responsibility while promising prosecutionsNotable Point
The Serbian reply combines claims of peaceful conduct with denials of responsibility, conditional prosecutions, and a promised declaration against anti-Austrian propaganda.
- 53:46The legal qualifications in Serbia's promise to suppress hostile publicationsNotable Point
Promises to punish hostile publications depend on later changes to the press law and constitution, illustrating the qualifications within Serbia's concessions.
- 55:28QuestionHave you read The Darkest Days on the same subject as Clive Ponting's 13 Days?AnswerQ&A
Yes, and it is worth reading. Ponting's account is preferred here for its treatment of the Serbian side.
- 1:04:17A Midway anthology built from specialists and participantsChapter
Thomas C. Hone's Midway anthology combines specialist scholarship with participant accounts, including Spruance, Layton, and Jimmy Thach.
- 1:07:54Why Jimmy Thach chose to escort Yorktown's torpedo bombersNotable Point
Yorktown's scarce Wildcats accompanied the vulnerable TBD Devastators because Thach expected Japanese fighters to concentrate on the torpedo attack.
- 1:11:35Fitting six Wildcats around a slow torpedo formationNotable Point
A late cut to six Wildcats forced a four-plus-two escort arrangement, while S-turns kept the fighters beside the slower TBDs without sacrificing manoeuvring speed.
- 1:13:36Why the Thach Weave used four fighters in two sectionsNotable Point
Adopting two-plane sections and adopting the weaving manoeuvre were separate steps; Flatley's reported comparison supported a four-aircraft division.
- 1:17:20QuestionWhy might Bf 110 units not have developed formation tactics similar to the Thach Weave?AnswerQ&A
The suggested reason is that the Bf 110 faced different opponents and performance relationships, making the same crossing mutual-support tactic less attractive.
- 1:19:10QuestionWould taking an Atlanta-class cruiser to the battles of Narvik be useful?AnswerQ&A
An Arethusa-class cruiser is the preferred choice in this counterfactual because its six-inch guns add heavier shells while British destroyers already supply rapid 4.7-inch fire.
- 1:23:03Comparing Roosevelt's naval ideas with the policies he carried outNotable Point
Pairing Roosevelt's own writing with a study of his diplomacy allows his stated naval ideas to be compared with decisions made in office.
- 1:26:06Roosevelt's private warnings in Hendrix's account of the Venezuela crisisChapter
Hendrix's account connects a private ultimatum and Dewey's fleet with German acceptance of arbitration during the Venezuela crisis.
- 1:28:06British food imports and the risk of a second war across the AtlanticNotable Point
A British memorandum linked limited fleet availability with dependence on Canadian and American food supplies during a possible Atlantic war.
- 1:30:03Panama's revolt and the evidence for War Portfolio Number OneChapter
Hendrix separates the uncertain origins of Panama's revolt from the documented American contingency plan to defend a new republic.
- 1:34:15Payments and sovereignty in the Hay-Herran Treaty disputeNotable Point
The canal negotiations stalled over Colombian sovereignty and additional payments after the United States had accepted several changes to the original terms.
- 1:43:03Britain's Naval Future defines limited sea controlChapter
James Cable treats sea control as the ability to use maritime communications, with practical limits set by time, geography, opponents, and available forces.
- 1:47:44A battle fleet built for a blockade that never cameNotable Point
Cable argues that German planning expected a close blockade, while British planning underestimated the submarine threat to trade.
- 1:49:18Cable's criticism of Britain's prewar allocation of resourcesNotable Point
Cable questions the resources committed to the expeditionary army and bombing, while admitting that the outcome of his proposed maritime alternative cannot be proved.
- 1:51:03Why preventing invasion matters more than every hostile passageNotable Point
Cable distinguishes decisive control, such as stopping an invasion, from a temporary enemy passage that humiliates a navy without deciding the conflict.
- 1:53:23QuestionWere the Black Buck raids worth their cost, and did the hit on Stanley's runway materially help win the Falklands War?AnswerQ&A
Psychological pressure and diverted Argentine fighters were the strongest benefits identified; continued Hercules flights undermine the claim that runway damage severed the air bridge.
- 1:55:30QuestionAfter the Falklands War, which Royal Navy decisions should have been retained or expanded, and what should have been replaced?AnswerQ&A
Replace outdated ships with modern Type 22 and Type 23 frigates, consider the preferred Type 43 alternative, and preserve the ability to fight wars beyond the central NATO scenario.
- 1:58:27QuestionWhat do you think of the stretched Type 22s?AnswerQ&A
The broad-beamed Type 22s were a good design.
- 2:01:10James Cable beyond Corbett and MahanNotable Point
Britain's Naval Future and Gunboat Diplomacy provide recommended reading beyond the familiar Corbett and Mahan pairing.
- 2:03:01QuestionHow much of a threat were Argentine Canberra aircraft during the Falklands War?AnswerQ&A
Their reconnaissance work was useful, but they are judged to have contributed little beyond it.
- 2:04:40How the Landing Craft Assault balanced beaching, protection, and troop movementChapter
Brian Lavery's Landing Assault Craft relates the LCA's hull shape, grounding battens, bow ramp and seating to beaching and landing troops.
- 2:08:18LCA steering, armour and machinery arrangementsNotable Point
The LCA gave its coxswain adjustable protection and indirect engine control, while armour, communications and removable seating supported assault and cargo duties.
- 2:12:10QuestionDo large lake and river crossings count as amphibious operations, and could D-Day technically be treated as a river crossing?AnswerQ&A
Convention calls D-Day amphibious, but because it launched from land and crossed water to another shore, it can technically be compared with a very large river crossing.
- 2:13:12QuestionWere soldiers inside the Landing Craft Assault partially covered?AnswerQ&A
The compartment was not fully covered, but troops on the outer benches could shelter beneath the side decks.
- 2:15:41Northrop's 3A, Vought's Model 143, and the Zero ancestry mythNotable Point
Heinemann recalls how Northrop's 3A design package passed to Chance Vought and later to Japan, while rejecting the claim that it became the Mitsubishi A6M Zero.
- 2:16:42The XBT-1 specification for vertical carrier dive bombingChapter
A thousand-pound bomb, nine-g pullout and 250-knot vertical dive made brake design and structural strength central to the Navy's new carrier bomber.
- 2:18:44Pricing the XBT-1 through engineering experienceNotable Point
Heinemann's surprise at a rapid $64,000 estimate becomes a recollection about the practical judgment acquired through years of aircraft development.
- 2:19:26Making the XBT-1's flaps serve as landing aids and dive brakesNotable Point
Separate landing and dive-brake modes required synchronized flap movement so deployment would not upset the XBT-1's trim.
- 2:20:31Photographing the XBT-1's dangerous tail flutterNotable Point
Repeated dives and onboard photographs revealed two-foot tail-tip movement, leaving the XBT-1 unable to use its brakes safely.
- 2:23:03NACA's perforated-flap solution restores a stable vertical diveNotable Point
Three-inch holes broke up the vortices behind the dive brakes, curing flutter while raising a separate concern about carrier landing speed.
- 2:25:09QuestionWas Narvik the first Allied amphibious landing of the Second World War with tanks?AnswerQ&A
The tanks followed the troops much later and arrived in very small numbers.
- 2:26:17Castle-class corvettes ship by shipChapter
Dumbarton Castle's record connects working up, an uncertain gap in movements, eight successful convoy escorts and postwar reserve service.
- 2:30:37Dumbarton Castle's officers and a disputed propeller improvementNotable Point
A commissioning memoir pairs specialist officer training with Broadhead's proposal to improve the corvette's speed by changing propeller pitch.
- 2:32:58Monkey Stephenson's working-up drills demanded initiativeNotable Point
Emergency drills, surprise night visits and enforced retraining tested whether escort officers could respond and make their crews think.
- 2:34:20Gibraltar convoys, escort carriers and refuelling dutiesNotable Point
Gibraltar escort work combined a wide Atlantic route, carrier flying support, tanker movements and recurring boiler maintenance.
- 2:35:27Operating ASDIC and Squid aboard Dumbarton CastleNotable Point
Squid and ASDIC depended on a small specialist team, while awkward external sonar-dome handling could delay the ship's departure.
- 2:36:48A smallpox warning prompts vaccination at seaNotable Point
A passenger doctor vaccinated Dumbarton Castle's crew after a smallpox warning made recent vaccination a condition for going ashore in Gibraltar.
- 2:38:16Edward I's castles around north WalesNotable Point
Conwy was part of Edward I's extensive castle building around north Wales.
- 2:40:43QuestionWere only fourteen Castle-class corvettes completed?AnswerQ&A
The class history lists 39 entries across British, Canadian, and Norwegian service; the apparent fourteen-ship total came from overlooking additional tables.
- 2:42:45QuestionWhen did electric searchlights begin appearing on warships?AnswerQ&A
Royal Navy operational use is documented at Alexandria in 1882, while the U.S. Navy appears to have experimented with fittings around 1881.
- 2:43:46Japan's C1 attack submarines and their midget-submarine fittingsChapter
Eight bow torpedo tubes and midget-submarine fittings gave Japan's C1 boats a concentrated attack role, before supply conversions reduced their armament.
- 2:45:42C1 operations from Pearl Harbor to supply missions and lossesNotable Point
The C1 boats combined distant midget attacks and commerce raiding with supply missions before all five were lost or went missing.
- 2:49:12Supermarine's unexpected naval aircraft proposals beyond the SpitfireChapter
Beyond the Spitfire reveals Supermarine studies for naval service, including a twin-engined biplane intended to answer the same requirement that produced the Swordfish.
- 2:52:41Frank Whittle's RAF service and Power JetsNotable Point
Whittle's company attachments remain uncertain as his RAF service is compared with the history of Power Jets.
- 2:53:37Mitchell's biplane benchmark and the road to the F.7/30 fighterChapter
R. J. Mitchell developed biplane and monoplane studies in parallel, using Rolls-Royce evaporative cooling and early wind-tunnel work before the F.7/30 requirement formally appeared.
- 3:00:12QuestionHow good might a Supermarine alternative to the Fairey Swordfish have been?AnswerQ&A
It sounds appealing, but reliability and the ability to produce enough aircraft are suggested reasons for the Fairey choice.
- 3:01:40Why aircraft project lists can remain incompleteNotable Point
Classified work and abandoned drawing-board studies can leave gaps even in apparently complete aircraft-design inventories.
- 3:03:05U.S. Marine Corps aviation and the Corsair's reputationChapter
A history beginning in 1912 introduces Marine aviation through the Corsair and the Royal Navy's contribution to its development.
- 3:04:36The Panther, swept-wing Cougar, and Marine aviation rolesNotable Point
Swept wings turned the Panther lineage into the Cougar, whose Marine roles included reconnaissance, attack, and forward air control.
- 3:06:32Marine squadrons and the early transition to carrier jetsNotable Point
A Marine squadron's move from Corsairs through Panthers to FJ2 Furys sits within the Navy's wider introduction to carrier jets.
- 3:10:32British submarine production, the A class, and special-purpose designsChapter
Wartime submarine development balanced improvements against disruption to construction, with the A class and small special-purpose craft making different demands on designers.
- 3:14:08S-class submarines: welding, armament, and Far Eastern enduranceNotable Point
Welding improved S-class hulls and made external fuel stowage practical, helping adapt a confined-water patrol submarine for longer voyages.
- 3:16:19U-class submarines: simple machinery and revised bow arrangementsNotable Point
U-class production benefited from simple machinery, while revised bows and quick-diving tanks addressed handling and firing problems.
- 3:18:16T-class submarines: construction priorities and a stern-firing salvoNotable Point
The T class combined patrol capability with revised torpedo arcs, while wartime demand for numbers limited construction of the larger boats.
- 3:21:03Black Swan-class sloops through builders' plansChapter
Detailed builders' plans expose the Black Swan class's internal arrangement, weapons, depth-charge gear, Hedgehog mortar, and ship-to-ship differences.
- 3:29:59A contemporary guide to the late Soviet NavyChapter
Norman Polmar's fifth edition records the Soviet Navy near the end of the Cold War and introduces a reading on amphibious ships.
- 3:32:33Ivan Rogov combines beaching, docking, helicopters, and heavy weaponsNotable Point
The Ivan Rogov-class entry shows a Soviet landing ship designed to beach vehicles, operate landing craft from a well deck, fly helicopters, and defend itself with missiles, guns, and rockets.
- 3:32:52Soviet amphibious capacity and the limits of listed troop numbersNotable Point
A 1991 fleet assessment separates ship numbers from short-range lift and explains why berth counts can understate troops carried on brief crossings.
- 3:40:50QuestionKnowing what is known now, what changes would improve Royal Navy and U.S. Navy fleets against the Soviet Navy?AnswerQ&A
Introduce close-in defenses earlier, build larger British and American surface combatants, and retain quiet diesel submarines for chokepoint and barrier operations.
- 3:45:07Stalin's purges and Red Army readiness in 1941Notable Point
Stalin's purges weakened the Red Army's experienced leadership before its fighting against Germany.
- 3:46:21QuestionWith more Type 82s coming into service, would the Kirovs have been taken more seriously?AnswerQ&A
Their cost and priority as submarine targets receive greater emphasis, alongside the possibility that larger Western ships could stimulate further Soviet spending.
- 3:47:50QuestionWhat changes would have improved Britain's anti-submarine fleet before and during the Second World War?AnswerQ&A
Begin mass-producing versatile sloops much earlier, match them to destroyer construction, and prepare merchant hulls for rapid escort-carrier conversion.
- 3:53:13QuestionIs the Royal Navy building LCS-type ships?AnswerQ&A
The concept discussed is the Littoral Strike Ship, or LSS, initially intended for special operations and about a company of Marines.
- 3:55:50QuestionWhy not use one Littoral Strike Ship hull type for different troop capacities?AnswerQ&A
The proposal receives a sceptical response without a technical comparison. Ship numbers remain uncertain, and an LHD is suggested as one possible outcome.
- 3:56:23QuestionWere Littoral Strike Ships intended for the Marines, SAS, SBS, and Parachute Regiment?AnswerQ&A
Royal Marines and SBS are identified, SAS is possible, and Parachute Regiment involvement is doubted.
