The 239th Infantry Regiment
The paper that reached the rainy shore first — on the regiment Tamura Yoshikazu belonged to

This page is not here to tell a unit's battle history. Behind one man's diary (Tamura Yoshikazu), there was another sheet of paper — the decision that sent him to that shore. This page exists so that this paper, and the notebook that recorded rain and the moon, can be seen side by side.

Why was this regiment at Wewak?

Tamura Yoshikazu landed at Wewak, New Guinea, as a member of the 239th Infantry Regiment, formed in Utsunomiya. When he wrote "February — the rains of Wewak" in his notebook, he was in the regiment's advance party — among the first to reach the island.

Why was the second son of a Tochigi farming family on a southern island five thousand kilometers away? It was not something he decided. Another sheet of paper — a decision that moved whole units — carried him there.

What was the 239th Infantry Regiment? 🟢 Confirmed

• A regiment formed in Utsunomiya, one of the three infantry regiments of the 41st Division (with the 237th of Mito and the 238th of Takasaki).
• The 41st Division was originally created in 1939 for garrison and security duty in mainland China (Shanxi Province). For about three years it stood guard on the continent.
• Then, in November 1942, it was redeployed from north China to New Guinea. Tamura's 239th Regiment, as the division's advance party, reached Wewak in eastern New Guinea in late February 1943.

"February — the rains of Wewak" in Tamura's notebook falls exactly in this landing period. The rain he wrote down was the first rain of the first unit ashore.

Tamura's call-up: Utsunomiya, 239th Infantry Regiment — recon tier verification.

The other sheet of paper — into a front already crumbling 🟢 Confirmed

The question is what moment in the New Guinea campaign this redeployment fell into.

By the time Tamura's unit reached Wewak, the front in New Guinea was already tilting. The nearby 51st Division had been defeated at Lae and Salamaua; the 20th Division that followed suffered heavy losses at Finschhafen; the 18th Army was approaching collapse. A garrison division had been sent, as reinforcement, into a crumbling front line on a vast island with the thinnest of supply lines.

After the failure at Aitape in July 1944, the remaining units withdrew into the mountains and fought a war against hunger. On this island, it was not only enemy fire — starvation and disease felled soldier after soldier. Even the division's commander died of illness before the battle (Lieutenant General Abe Heisuke, June 1943).

Tamura died in this collapsing front, at Biliau, in March 1944. The notebook of rain, the moon, and poems closes there.

These two sheets of paper met on the same New Guinea shore.

Sources: history of the 41st Division (defeat of the 51st Division at Lae–Salamaua; losses of the 20th Division at Finschhafen; near-collapse of the 18th Army; July 1944 Battle of Aitape → starvation in the mountains; division commander Abe Heisuke died of illness June 1943) — verified against primary text. Tamura's death: "killed in action at Biliau, March 1944" (death notice; AJRP). ⚠️ The circumstances of Tamura's own death (in combat, or amid the collapse) are not asserted. The division's starvation is fact; we do not conclude that Tamura himself died of it.

Fragments of this unit

• The one fragment of this regiment that can be read with certainty today is Tamura Yoshikazu's notebook — translated, its name recovered, a book that made it home.
• Diaries and letters of others in the same regiment may yet be found. If they are, new fragments will join this page.
