Definition

The 38th Infantry Division — the “Cyclone Division,” from the tornado that struck its Camp Shelby, Mississippi training ground in 1918 — is an infantry division of the United States Army raised from the National Guards of Indiana, Kentucky, and West Virginia, with its headquarters activated at Camp Shelby on August 25, 1917 and its postwar home in Indianapolis, where it stands today as an Army National Guard division headquarters at Stout Field. (Wikipedia — 38th Infantry Division) In World War II the division fought the second half of its war in the Philippines — Hawaii (from January 1944), New Guinea, Leyte (December 1944), and then Luzon, where it landed on the Zambales coast on January 29, 1945, broke the Nagayoshi Detachment at ZigZag Pass in the February 1–14 fighting, cleared Bataan, and fought the Corregidor-area and Shimbu Line operations — “198 consecutive days in combat” against “more than 80,000 Japanese,” killing 26,732 and taking more than 13,000 prisoners. (Wikipedia — 38th Infantry Division, CMH — Back to Bataan) From the Bataan fighting the division took its second name, the “Avengers of Bataan,” ordered by Maj. Gen. William C. Chase after the peninsula was cleared “in 19 days of bloody combat” — a tribute often attributed to General MacArthur. (Wikipedia — 38th Infantry Division)

The division’s Philippine command ledger runs from Maj. Gen. Henry L. Jones through Chase to Maj. Gen. Frederick A. Irving: Jones was relieved on February 6, 1945 during the stalled ZigZag attack, Brig. Gen. Roy W. Easley held the division for a day, and Chase commanded from February 7 to July 1945 — the dating this wiki’s William C. Chase entry carries — before Irving took over for the inactivation, at the cost of 3,464 battle casualties in the war. (CMH — Back to Bataan, Wikipedia — William C.

Examples and Analogies

A National Guard division that kept its home: the 38th was three states’ guardsmen in 1917, an Indiana-headquartered force after 1947, and today a multi-state National Guard headquarters still wearing the “CY” monogram patch of the Cyclone name. (Wikipedia — 38th Infantry Division)
A green division baptized in a defile: at ZigZag Pass the 152nd Infantry — in combat “scarcely forty-eight hours” — ran into a fortified horseshoe it had estimated might hold as few as 900 Japanese instead of the 2,750 dug in: the trial by fire that preceded the Avengers name. (CMH — Back to Bataan)
The Philippines as one continuous campaign: from the Leyte airstrips in December 1944 — where the 149th Infantry “destroyed organized resistance” on December 11 after enemy paratroop attacks — through Bataan, the bay islands, and the Shimbu Line, the division fought a single Philippine arc.

Usage Scenarios

1. The Bataan Campaign of 1945

The division is the attacking half of the ZigZag Pass record this wiki’s entry carries: the 152nd’s first assault of February 1, the 149th’s bypass march to Dinalupihan, the 151st’s insertion, and the Mariveles landing of February 15 by the 151st RCT under Chase’s direct command. (CMH — Back to Bataan, Wikipedia — Battle of Bataan (1945))

2. Opening Manila Bay

With Bataan came the bay: the peninsula’s clearing — the 38th’s mission — was the first step of the Sixth Army plan that continued against Corregidor from February 16 and the southeastern islands, where division elements operated into April. (CMH — Back to Bataan, Wikipedia — 38th Infantry Division)

3. The Shimbu Front East of Manila

In late April 1945 the division relieved the 6th Infantry Division east of Manila and attacked into the Shimbu Line from May 1, the Wawa Dam secured by month’s end — the front this wiki’s Shimbu entries carry. (Wikipedia — William C. Chase, Wikipedia — 38th Infantry Division)

4. A Reserve Component Across a Century

The postwar 38th is the standing case of National Guard continuity — from the 1947 reconstitution through Vietnam’s Ranger company to Task Force Cyclone’s 15,500 Guardsmen in Katrina-struck Mississippi and the Afghanistan headquarters tour. (Wikipedia — 38th Infantry Division)

Strategies

Two axes across a peninsula base: at the ZigZag the division attacked along Route 7 with the 152nd while the 149th bypassed north to Dinalupihan — mutually supporting columns that sealed Bataan even before the pass fell. (CMH — Back to Bataan)
Trade tempo for firepower after failure: the Jones plan of methodical, artillery-first reduction — condemned as slow on February 6 — became the method that prevailed once napalm-equipped P-47s and massed artillery joined the fight. (CMH — Back to Bataan)
Amphibious envelopment on Bataan: with the pass reduced, South Force (the 151st RCT) landed at Mariveles on February 15 while East Force (the 6th Division’s 1st RCT under the 38th’s artillery commander Brig. Gen. William Spence) drove down the east coast, the two meeting below Bagac on February 21. (CMH — Back to Bataan)
Reserve continuity as institution: the postwar strategy was presence — an Indiana headquarters, aligned brigades across states, repeated federal activations. (Wikipedia — 38th Infantry Division)

Security and Safety Measures

The division’s ledger: 3,464 battle casualties in World War II (645 killed, 2,814 wounded, 5 missing) against 26,732 Japanese killed — the arithmetic of Bataan, the bay islands, and the Shimbu Line combined. (Wikipedia — 38th Infantry Division)
The ZigZag cost: about 1,400 casualties including 250 killed in destroying the Nagayoshi Detachment, of which the attached 34th Infantry alone lost 325 in three days; the official history’s caution on piecemeal commitment in jungle defiles. (CMH — Back to Bataan)
Command accountability as a safety mechanism: the relief of Jones for “lack of aggressiveness… unsatisfactory tactical planning and execution and inadequate reconnaissance measures” — the documented price of perceived command failure. (CMH — Back to Bataan)
For researchers: CMH styles the relieved commander “Henry L. C. Jones” and the division article “Henry L. L. Jones”; keep the February 6 relief, Chase’s February 7 assumption, and Irving’s August assumption distinct; and carry the landing-styling variance (San Antonio in the official history, San Narciso in the division article) with attribution. (CMH — Back to Bataan, Wikipedia — 38th Infantry Division)

Historical Context

The 38th was born in the 1917 mobilization — Indiana, Kentucky, and West Virginia guardsmen at Camp Shelby — and named by a tornado: the April 1918 cyclone that killed Private Vaughn D. Beekman led Maj. Gen. Robert L. Howze to announce that “the division would be known in the future as the ‘Cyclone Division.'” (Wikipedia — 38th Infantry Division) Inducted again in January 1941 and reorganized triangular in 1942, the division rehearsed in Hawaii and New Guinea before Leyte in December 1944, where its 149th Infantry finished off organized resistance around the airstrips the Japanese paratroopers of the Teishin Shudan’s December 6 raid had tried to destroy. (Wikipedia — 38th Infantry Division)

Luzon made its reputation. Landing on the Zambales coast on January 29, 1945, the division drove across the base of Bataan into the ZigZag; the stalled first week cost Jones his command and brought Chase forward from the Manila dash; the 151st landed at Mariveles on February 15; and on February 21 Bataan was again in American and Filipino hands. (CMH — Back to Bataan, Wikipedia — Battle of Bataan (1945)) Chase ordered the Avengers of Bataan styling from that record; the division went on to the bay islands and the Shimbu Line, returned home in October 1945, and was inactivated on November 10. (Wikipedia — 38th Infantry Division, Wikipedia — William C. Chase)

Rebuilt in Indiana in 1947, the Cyclone Division lived the whole National Guard arc — Pentomic and ROAD reorganizations, the Vietnam Ranger company, Katrina, Afghanistan, Iraq, and the 2021 inauguration security — and stands today at Stout Field, Indianapolis, commanding brigades from Indiana and aligned states. (Wikipedia — 38th Infantry Division)

Challenges and Controversies

The Relief of General Jones

The division’s defining controversy is the February 6, 1945 relief: Hall’s condemnation of a division most of which had seen no action, delivered against a commander whose slow method was dictated by terrain the corps had underestimated — the official history itself records that Jones and the 38th were “more nearly correct” about the Japanese main line of resistance than was XI Corps. (CMH — Back to Bataan)

Who Named the Avengers

The “Avengers of Bataan” styling is carried as Chase’s order after the 19-day clearing, “often attributed to General Douglas MacArthur” — an unresolved attribution, cited rather than settled. (Wikipedia — 38th Infantry Division)

Nineteen Days or Twenty-One

The Avengers arithmetic (“19 days of bloody combat”) sits beside the campaign dates the corpus carries — fighting from February 1, Bataan secure February 21 — and the two spans measure different starts. (Wikipedia — 38th Infantry Division, Wikipedia — Battle of Bataan (1945))

The Reserve Readiness Question

From the green 152nd at the horseshoe to the politics of every later mobilization, the 38th’s history keeps alive the standing American debate over National Guard readiness — a controversy its combat record answers in part and its relief record complicates.
