Time notes
- 8:01Treaty tonnage and ships fitted for equipment they do not carryNotable Point
A modern treaty counterfactual imagines British ships reaching their tonnage limits while carrying less armament than their hulls were designed to accept.
- 11:05QuestionWhat difference would Greenboy shells have made at Jutland?AnswerQ&A
Seydlitz would not have made it home if more of the shells that struck her had exploded, given how badly damaged she already was.
- 12:29QuestionWhy had piracy grown when Rome controlled the Mediterranean after the Punic Wars?AnswerQ&A
Rome did not maintain a standing navy to suppress it.
- 24:28Ellwood as a visible coastal targetNotable Point
Ellwood's undefended oil facilities and good communications made it a conspicuous coastal target where an attack would quickly attract attention.
- 27:37Japan's thin submarine patrol off the West CoastNotable Point
Seven Japanese submarines produced real disruption off an enormous coastline, exposing the mismatch between American capital-ship construction and its shortage of small escorts.
- 31:15I-17 and Kozo NishinoNotable Point
I-17 combined torpedoes, a deck gun, and a seaplane under a career submarine commander whose background contradicts the popular revenge story.
- 32:03QuestionWhat is wrong with building a tanker?AnswerQ&A
Nothing, provided the fleet also builds an escort ship to protect it.
- 35:48What the Ellwood bombardment actually hitChapter
I-17 fired for twenty minutes at Ellwood's fuel installations, missing the tanks while damaging a derrick, pump house, and nearby structures.
- 44:30What I-17's 5.5-inch deck gun could doNotable Point
I-17's gun specifications put the Ellwood shell estimates in perspective: its theoretical rate of fire greatly exceeded the likely bombardment total.
- 46:33Ellwood and the Battle of Los AngelesNotable Point
The Ellwood raid primed defenders for the Battle of Los Angeles, when confused warnings and mass anti-aircraft fire caused casualties without a confirmed enemy aircraft.
- 53:40QuestionDid defenders actually hit the meteorological balloon associated with the Battle of Los Angeles?AnswerQ&A
No. The balloon is a later probable explanation for the alert, but there is no indication that the anti-aircraft barrage hit it.
- 58:28Why Baltimore was defended differently from WashingtonChapter
The contrast between the burning of Washington and the defense of Baltimore explains an older American memory of coastal attack and invasion.
- 1:02:05An uncertain staff-college wargame of the War of 1812Notable Point
A secondhand wargame story changes British command and troop numbers to explore a different War of 1812.
- 1:04:16Britain's three-pronged campaign in 1814Chapter
The Baltimore expedition belonged to a wider British attempt to pressure several American ports while veteran manpower and naval forces were becoming available after the Napoleonic Wars.
- 1:12:54North Point, Fort McHenry, and the British withdrawalChapter
American delaying action at North Point and Fort McHenry's denial of naval fire support made a direct assault on Baltimore too costly for the British plan.
- 1:20:56Wartime news and British support for continued fightingNotable Point
Intermittent news, reports of victories, and hostility to perceived support for Napoleon explain continued British support for the war.
- 1:22:20Checking the claim that Wellington visited CanadaNotable Point
Wellington's post-Waterloo appointments leave no obvious time for a Canadian visit, despite local traditions associating his name with the country.
- 1:26:26QuestionWas the claim that America stabbed Britain in the back by siding with Napoleon merely propaganda?AnswerQ&A
It also reflected a sincere British public view that the United States had attacked while Britain was fighting Napoleon, whom many Britons regarded as Europe's great enemy.
- 1:27:33U-156 and the 1918 action off OrleansChapter
During the Orleans action, a German U-boat attacked coastal traffic, exchanged fire with flying boats, and accidentally sent shells onto American soil.
- 1:28:29Why U-156 would conserve its torpedoesNotable Point
U-156 carried far more gun ammunition than torpedoes, making gunfire a plausible choice against a slow tug and its tows.
- 1:37:28QuestionDid U-152 visit Rhode Island closely enough for crewmen to go ashore and buy newspapers?AnswerQ&A
The story and submarine number remain uncertain, although that kind of bold visit was plausible for the large German cruiser-submarine family.
- 1:39:34The Peter Iredale wreck beside Fort StevensNotable Point
The four-masted barque Peter Iredale links Fort Stevens to an earlier story of sail, grounding, rescue, and an unsuccessful salvage attempt.
- 1:46:32Fort Stevens and submarine gunfire limitsNotable Point
The Japanese shelling of Fort Stevens produced far more alarm than military damage.
- 1:52:43Could the post-Napoleonic settlement reopen the Louisiana Purchase?Notable Point
Renewed European claims to the Louisiana Purchase were a speculative post-1814 possibility that linked diplomacy to the problem of demobilizing Napoleon's veterans.
- 1:54:33QuestionDid they upgrade the guns at Fort Stevens?AnswerQ&A
Yes, eventually.
- 1:55:20Why Japan occupied the Aleutian IslandsChapter
The occupation of Attu and Kiska served several aims at once: protecting Japan's northern approaches, complicating the Midway campaign, and claiming American territory for psychological effect.
- 2:02:20QuestionWas Japan's Aleutian operation intended to lure American carriers north and draw the main Japanese fleet after them?AnswerQ&A
It had a diversionary role and also served Japan's effort to extend its defensive perimeter.
- 2:04:48Kinkaid's path from battleships to North Pacific commandNotable Point
Kinkaid brought battleship, ordnance, cruiser, and carrier-task-force experience to the recovery of the Aleutians.
- 2:07:18Hosogaya's withdrawal at the Komandorski IslandsNotable Point
Hosogaya's apparent surface advantage at Komandorski competed with the possibility of an unseen American carrier force.
- 2:12:54The carrier raids on Dutch HarborChapter
Two small Japanese carriers struck Dutch Harbor, damaged its facilities, and inadvertently gave the United States a recoverable Zero fighter for technical study.
- 2:13:28Ryujo, Junyo, and the limits of carrier readinessNotable Point
The Dutch Harbor carrier force combined Ryujo's small hull with Junyo's limited time to work up after conversion.
- 2:16:12Dutch Harbor's improvised ground defenseNotable Point
Gun crews, infantrymen, and civilian contractors improvised defenses during and between the two Japanese raids on Dutch Harbor.
- 2:23:53Aleutian supply lines and the unfinished Alaska HighwayNotable Point
The Alaska Highway was newly authorized when the Aleutian campaign began, leaving American forces dependent on distant support.
- 2:25:31Kiska's weather station and William House's evasionChapter
Kiska's tiny weather-station detachment was overwhelmed, while William House evaded capture for fifty days before starvation forced his surrender.
- 2:27:54QuestionWas the captured Akutan Zero an advanced prototype whose study led to improvements in the F6F Hellcat?AnswerQ&A
It was an improved Zero variant rather than an advanced prototype, but its recovery still revealed the newer variant's characteristics at close range.
- 2:28:58QuestionWhat effect would an American attack on Japan along the Aleutian chain have had on defenses elsewhere?AnswerQ&A
It was possible in theory, but currents, distance, cold, and the extra support burden made the Aleutian route much harder than the routes the Allies actually used.
- 2:30:23Evacuating Kiska through the American blockadeNotable Point
Fog allowed two Japanese light cruisers and ten destroyers to evacuate 5,193 men from Kiska through the blockade.
- 2:32:42Attu's civilians under occupation and in captivityNotable Point
Attu's occupation brought civilian deaths, imprisonment in Japan, and permanent displacement of the surviving villagers.
- 2:34:33Attu's empty interval and costly American recaptureChapter
An unnoticed interval without a Japanese garrison preceded the costly American landing on Attu in May 1943.
- 2:39:39QuestionWould Japan's plan for 6,300 improved A6M8 Zero fighters have materially changed the war?AnswerQ&A
Yes, if Japan could actually build, fuel, crew, and operate them; the paper total alone could not create combat power.
- 2:43:22Kiska's evacuation and Operation CottageChapter
Japan evacuated Kiska before the Allied landing, yet mines, booby traps, and friendly fire made Operation Cottage costly against an absent garrison.
- 2:46:00Radar uncertainty in the Battle of the PipsNotable Point
Uncertain radar contacts prompted two American battleships to fire 518 fourteen-inch shells without a confirmed target or hit.
- 2:47:40QuestionCould Kiska's radio silence have meant that the Japanese were using a telephone cable?AnswerQ&A
Installing a cable through the American blockade would itself have been an extraordinary engineering operation; the combined signs of evacuation warranted reconnaissance.
- 2:49:19QuestionIf global war were delayed until 1945, would Japan's later carrier aircraft give it a decisive advantage?AnswerQ&A
Britain and the United States would also gain years to develop their fleets, industry, and overseas support infrastructure.
- 2:51:25QuestionWho made the first carrier landing by a jet aircraft, and did the United States get there first?AnswerQ&A
Eric Brown made the first controlled carrier landing and takeoff by a pure jet in a Sea Vampire aboard HMS Ocean in December 1945, while the earlier American Ryan FR Fireball arrival was a crash landing by a mixed-power aircraft.
- 2:54:01QuestionWould Britain have Centurion tanks if the war began later?AnswerQ&A
Possibly, but the Army might keep developing its existing tanks without wartime experience, so the timetable could differ.
- 2:57:06Yamato and British battleship retention in a delayed warNotable Point
Discovery of Japan's 18-inch-gun battleships could change which British capital ships were retained or modernized before a later war.
- 3:01:48QuestionDid Japan plan submarine-carried commando raids against the United States?AnswerQ&A
Japan had both long-range submarines and naval landing troops, but it does not appear to have combined them into such a plan, even though the concept was feasible.
