    How do you defend an island nation when 40% of your trade flows through contested waters?

    Forty percent of Australian trade flows through the South China Sea — and if conflict erupts near Taiwan, that route becomes uninsurable overnight. Maritime strategist Mark Bailey argues that Western continentalism has left island nations dangerously unprepared for the Indo-Pacific's return to its ancient strategic shape, where China and India once again compete for influence over Southeast Asia. This keynote address traces how Beijing treats the South China Sea as sovereign territory to be garrisoned, why Tokyo has quietly reorganised its navy for convoy escort, and what the Taiping Rebellion's 20–80 million dead reveal about Chinese internal fractures.

    This is a special seminar presentation in conjunction with the Royal Australian Artillery Historical Company's Firepower Seminar Series, "Firepower: Lessons from World War II" Our presenter is Dr Mark Bailey, presenting our keynote presentation.

    Key learnings: • Why Japan restructured its fleet into three convoy escort groups anticipating wartime shipping protection • How Chinese hybrid warfare operates through United Front university networks, cyber intrusions, and fentanyl exports killing 80,000 Americans yearly • What Australia's 2023 Defence Strategic Review shares with Corbett's maritime principles

    Strategic Context for Australia's WW2 mobilisation

    Australia spent 20 years preparing for a war most politicians refused to discuss publicly — and that systematic industrial strategy may be the nation's greatest governance success story. Dr. Mark Bailey traces how bipartisan policy from 1919 built the secondary industry that would have annihilated Japanese forces had they landed at Port Stephens in 1942, while Major General Jason Blake connects those lessons to today's Army transformation through HIMARS, PrSM missiles, and the AS9 Huntsman.

    This is a special seminar presentation in conjunction with the Royal Australian Artillery Historical Company's Firepower Seminar Series, "Firepower: Lessons from World War II" Our presenter is Dr Mark Bailey and it is followed by our Panel Discussion with Major General Jason Blaine, DSC, AM, CSC and Dr Mark Bailey and Dr Peter Layton.

    Key learnings: • Why defence spending increased 20% in 1932-33 despite the Great Depression, following Japan's Manchurian invasion • How 730,000 soldiers mobilised from a population of 7 million through national census and preserved training infrastructure • What the shift from manoeuvre supporting fires to fires supported by manoeuvre means for modern Australian capability

    Australia's Road to War - 1936 to 1941 - Dr Peter Layton

    Australia built a coherent defence industrial strategy in the 1920s and 30s that actually worked when tested by total war — yet we've forgotten most of what made it succeed. This seminar recording pairs Dr Peter Layton's analysis of the interwar Munitions Supply Board with Major General Jason Blake's discussion of current Army modernisation.

    Key learnings: • How the self-containment strategy and 243 shadow factories enabled Australia to achieve munitions self-sufficiency by 1943 • Why Essington Lewis had to bypass service bureaucracies that refused to place orders even after the Fall of France • What the five-to-six-year lead time for establishing missile production means for current capability timelines

    149 - Why did the Marines stop 1,000 yards short of victory at 4th Matanikau - Guadalcanal

    After the defeat at Henderson Field, Japanese 17th Army headquarters remained confident — fresh divisions and hundreds of aircraft were promised within weeks. But Vandegrift had no intention of letting them regroup. This episode traces the Fourth Battle of the Matanikau and the emergency pivot to Koli Point, revealing how interior lines and improving logistics let the Marines mount the largest US Marine land attack in history to that date.

    Key learnings: • How Vandegrift assembled 12 battalions for an offensive while his perimeter forces were already exhausted after two and a half months • Why Japanese logistics could deliver only one-third of the 200 tons per day needed to sustain 30,000 troops on Guadalcanal • What Ultra intelligence revealed about Japanese landing plans and how it forced Vandegrift to split his forces

    148 - The Battle of Henderson Field - Guadalcanal 1942

    This episode is the 14th episode in our Guadalcanal series. We look at the Battle of Henderson Field, which is the decisive terrain for the campaign. Had the airfield been lost, it is likely that the US would not have been able to hold Guadalcanal.

    We discuss:

    How do you defend critical terrain against a numerically superior force?How should defensive positions exploit terrain to maximize effectiveness? How do you integrate combined arms in the defense? How does poor communication affect tactical coordination? How do you integrate unfamiliar units into ongoing operations? The 164th got their introduction into combat at Henderson Field. They were a North Dakota National Guard unit and had only been on Guadalcanal for 10 days. They were bought up to bolster the heavily outnumbered defences. Rather than have the unit deploy into the line and take over a part of the line, Puller had small groups lead into their positions next to Marines. Piecemeal deployment, the last thing you want to happen to your Regiment, but it employed the green troops to fight next to seasoned Marines. At the end of the fight, Chesty Puller said, "These farm boys can fight!"

    147 - The Japanese tank attack in the Battle of Henderson Field - Guadalcanal

    This episode looks at the Sumiyoshi's tank attack across the Matanikau - an attempt to draw defenders away from the perimeter of Henderson Field. We also discuss why Muryama coundn;t synchronise his forces and the dysfunction within the Japanese Headquarters.

    We look at -

    What are the consequences of relieving a subordinate commander on the eve of battle? (And what role did Tsuji play in Kawaguchi's dismissal?) What happens when multiple attacking elements operate independently without coordination? How should armour, infantry, and artillery be coordinated in an assault? What is the value of pre-registered artillery fires in defense? How can the Japanese achieve tactical surprise despite proximity? What is the purpose and risk of outposts forward of the main defensive line?

    146 - Halsey's question for Vandegrift about Henderson Field's defence that influenced Pacific Strategy.

    This episode looks at the defensive and offensive planning undertaken by the IJA and the USMC. It also looks closely at Vandegrift's meeting with Halsey and the outcome of the meeting. This is a pivotal moment in the campaign. Halsey has taken over from Ghormley and he prepares to back Vandegrift with everything the Navy has to help defend Guadalcanal.

    How does intelligence fusion enable a commander to choose the time and place of battle? The combination of coast-watchers, aerial photography, signals intercepts, prisoner interrogation, and traffic analysis gives Vandegrift sufficient warning to disengage from the Matanikau and assume a prepared defensive posture before the Japanese assault begins.

    What are the compounding effects of logistics failure on combat power? Japanese soldiers carry only five days' rations for a march that takes far longer than planned. By the time the assault goes in, troops are hungry, exhausted, and degraded — before they have fired a shot.

    How does the defence leverage knowledge of terrain? The defenders have patrolled and observed their ground for months, have pre-registered every likely approach, and understand the avenues of attack in detail — advantages the attacking Japanese, navigating by inaccurate maps in pitch darkness, completely lack.

    What is the relationship between strategic commitment and tactical success? The Marines' ability to hold Henderson Field is directly tied to whether higher command is willing to accept naval losses to keep the sea lanes open. Halsey's personal commitment to "give you all I have" is the strategic enabler for everything that follows tactically.

    How does the defender's advantage of fighting on familiar ground translate into combat power? Vandegrift's troops are dug in, know their sectors, have rehearsed their fire plans, and can rotate reserves along interior lines — while the Japanese are exhausted, disoriented, under-supplied, and attacking in darkness across ground they have never seen.

    145 - 973 rounds in 83 minutes. The Battleship Bombardment of Henderson Field

    This episode looks at the IJN and IJA combined planning for the assault on Henderson's Field, including the naval gunfire from the Kongo and Haruna under Rear Admiral Kurita where 973 14-inch rounds were fired in 83 minutes. We also discuss the development of the Maruyama Trail for the approach march of the 2nd Sendai Division. This episode discusses: What happens when commanders visualise terrain from a distance rather than conduct ground reconnaissance? How does poor mapping degrade operational planning? How does confirmation bias infect intelligence assessment? What is the relationship between terrain and combat power? What munition selection tells us about the limits of naval gunfire support against land targets? How do you maximise the effect of a fire support mission through observation planning? What does the Henderson Field bombardment teach us about fire saturation and its psychological effects? How does loss of aviation fuel translate directly into loss of air superiority? What is the danger of planning based on the timeline you want rather than the timeline the terrain imposes?
