The Pacific War dominates this week, and deservedly so β Mercogliano on shipyard logistics for Unauthorized History is the Pick, Holland and Murray's Japan countdown keeps building momentum, and Harris hits Midway's opening blows. Pierson on Trebizond and the Marian Reforms episode offer welcome detours for the rest of us.

Nearly two hours on US Navy shipbuilding from the mid-1930s programmes through the Two Ocean Navy Act, plus the underappreciated topic of fleet repair and maintenance in the Pacific β the kind of logistics story that actually explains how America won the war. Sal Mercogliano is a maritime historian who knows this material cold, and the discussion gets into the obscure admirals who ran the yards and the staggering production numbers. In a week stacked with Pacific episodes, this is the one that earns top billing: unsexy machinery-of-war content that rewards patient listening.
Holland and Murray continue their series on Japan's path to Pearl Harbor, here covering the military planning for attacking the United States and the final collapse of diplomatic negotiations. The interplay between European war developments and Pacific decision-making gets proper treatment, and Holland is good at explaining how institutional dynamics within the Japanese military shaped strategic choices. A series that keeps gaining momentum as it closes on the moment the Pacific became the centre of the war.
Part 3 examines how Japanese cultural norms around public versus private truth β honne and tatemae β contributed to the drift toward war, alongside the setting of hard deadlines for negotiations with the US. It's an unusual angle for a WWII podcast, connecting cultural dynamics to strategic decision-making in a way that doesn't feel gimmicky. Holland handles it with care, and Murray asks the right questions.
The Ancient Warfare team tackle one of the most debated topics in Roman military history β the Marian reforms and the shift from citizen militia to professional army. What makes this worth the time is the explicit focus on how far the traditional narrative of reform has been understood or misunderstood by modern historians. This is the kind of episode that rewards anyone who's read Goldsworthy or Keppie and wants to hear the arguments tested.
Robin Pierson covers 150 years of the Empire of Trebizond under the Grand Komnenoi, from 1297 through the Ottoman conquest in 1453. A solid continuation for anyone following this remarkable sequential history of Byzantium.
Lions Led By Donkeys covers the Fenian Ram β John Philip Holland's submarine built with Irish-American Fenian money to attack the Royal Navy. A good story about the intersection of revolutionary nationalism, early submarine technology, and naval warfare in the late 19th century.
Ray Harris Jr. gets into the opening exchanges of Midway β Fletcher's Yorktown versus Nagumo's First Air Fleet, covering the mistakes on both sides that shaped the Pacific War's most consequential carrier battle. Short at 25 minutes but squarely focused on the tactical detail of one of the conflict's decisive engagements.
Dan Snow and Crusades specialist Steve Tibble dig into the Assassins and Templars β their organisation, operations, and the reality behind the myth. Tibble is one of the better Crusades historians working today, and his focus on separating legend from documented history gives this more substance than the title suggests.
A book interview on the medical dimension of the Vicksburg campaign β how Union army medical officers innovated under siege conditions to sustain combat effectiveness across the 200-mile march and 47-day siege. Genuinely interesting intersection of logistics, medicine, and one of the Civil War's most important operations.
Steve Tibble joins Dan Snow to untangle the real history of these two orders from centuries of legend. The book digs into their beliefs, operations, and how myth calcified around both groups β essential reading if the episode leaves you wanting the full picture.
Privette reframes the Vicksburg campaign around the medical officers who kept Grant's army on its feet through disease, heat, and siege. A genuinely original angle on a campaign most people think they already know.
Holland and Murray's series on Japan's slide into war tracks the internal debates, cultural pressures, and diplomatic failures that made Pearl Harbor feel inevitable. Hotta's account covers exactly that ground from the Japanese side β the factional manoeuvring, the honne and tatemae of decision-making, and the point of no return.
Sal Mercogliano returns to the Unauthorized History pod to talk shipbuilding programmes and at-sea repair β his own work on naval logistics is the natural companion read for anyone who wants to understand how the US Navy kept fighting across the Pacific without sending every damaged ship stateside.
