Last time we spoke about The Battle of Suixian–Zaoyang-Shatow. Following the brutal 1938 capture of Wuhan, Japanese forces aimed to solidify their hold by launching an offensive against Chinese troops in the 5th War Zone, a rugged natural fortress in northern Hubei and southern Henan. Under General Yasuji Okamura, the 11th Army deployed three divisions and cavalry in a pincer assault starting May 1, 1939, targeting Suixian and Zaoyang to crush Nationalist resistance and secure flanks. Chinese commander Li Zongren, leveraging terrain like the Dabie and Tongbai Mountains, orchestrated defenses with over 200,000 troops, including Tang Enbo's 31st Army Group. By May 23, they recaptured Suixian and Zaoyang, forcing a Japanese withdrawal with heavy losses, over 13,000 Japanese casualties versus 25,000 Chinese, restoring pre-battle lines. Shifting south, Japan targeted Shantou in Guangdong to sever supply lines from Hong Kong. In a massive June 21 amphibious assault, the 21st Army overwhelmed thin Chinese defenses, capturing the port and Chao'an despite guerrilla resistance led by Zhang Fakui. Though losses mounted, Japan tightened its blockade, straining China's war effort amid ongoing attrition.

Well hello again, and yes you all have probably guessed we are taking another detour. Do not worry I hope to shorten this one a bit more so than what became a sort of mini series on the battle of Changkufeng or Battle of Lake Khasan. What we are about to jump into is known in the west as the battle of khalkin Gol, by the Japanese the Nomohan incident. But first I need to sort of set the table up so to say. So back on August 10th, 1938 the Litvinov-Shigemitsu agreement established a joint border commission tasked with redemarcating the disputed boundary between the Soviet Union and Japanese-controlled Manchukuo. However, this commission never achieved a mutually agreeable definition of the border in the contested area. In reality, the outcome was decided well before the group's inaugural meeting. Mere hours after the cease-fire took effect on the afternoon of August 11, General Grigory Shtern convened with a regimental commander from Japan's 19th Division to coordinate the disengagement of forces.

With the conflict deemed "honorably" concluded, Japan's Imperial General Headquarters mandated the swift withdrawal of all Japanese troops to the west bank of the Tumen River. By the night of August 13, as the final Japanese soldier crossed the river, it effectively became the de facto border. Soviet forces promptly reoccupied Changkufeng Hill and the adjacent heights—a move that would carry unexpected and profound repercussions. Authoritative Japanese military analyses suggest that if negotiations in Moscow had dragged on for just one more day, the 19th Division would likely have been dislodged from Changkufeng and its surrounding elevations. Undoubtedly, General Shtern's infantry breathed a sigh of relief as the bloodshed ceased. Yet, one can't help but question why Moscow opted for a cease-fire at a juncture when Soviet troops were on the cusp of total battlefield triumph.

Perhaps Kremlin leaders deemed it wiser to settle for a substantial gain, roughly three-quarters of their objectives, rather than risk everything. After all, Japan had mobilized threatening forces in eastern Manchuria, and the Imperial Army had a history of impulsive, unpredictable aggression. Moreover, amid the escalating crisis over Czechoslovakia, Moscow may have been wary of provoking a broader Asian conflict. Another theory posits that Soviet high command was misinformed about the ground situation. Reports of capturing a small segment of Changkufeng's crest might have been misinterpreted as control over the entire ridge, or an imminent full takeover before midnight on August 10. The unexpected phone call from Foreign Minister Maxim Litvinov to the Japanese embassy that night—proposing a one-kilometer Japanese retreat in exchange for a cease-fire along existing lines—hints at communication breakdowns between Shtern's headquarters and the Kremlin. Ironically, such lapses may have preserved Japanese military honor, allowing the 19th Division's evacuation through diplomacy rather than defeat.

Both sides endured severe losses. Initial Japanese press reports claimed 158 killed and 740 wounded. However, the 19th Division's medical logs reveal a grimmer toll: 526 dead and 914 injured, totaling 1,440 casualties. The true figure may have climbed higher, possibly to 1,500–2,000. Following the armistice, the Soviet news agency TASS reported 236 Red Army fatalities and 611 wounded. Given Shtern's uphill assaults across open terrain against entrenched positions, these numbers seem understated. Attackers in such scenarios typically suffered two to three times the defenders' losses, suggesting Soviet casualties ranged from 3,000 to 5,000. This aligns with a Soviet Military Council investigation on August 31, 1938, which documented 408 killed and 2,807 wounded. Japanese estimates placed Soviet losses even higher, at 4,500–7,000.

Not all victims perished in combat. Marshal Vasily Blyukher, a decorated Soviet commander, former warlord of the Far East, and Central Committee candidate, was summoned to Moscow in August 1938. Relieved of duty in September and arrested with his family in October, he faced charges of inadequate preparation against Japanese aggression and harboring "enemies of the people" within his ranks. On November 9, 1938, Blyukher died during interrogation a euphemism for torture-induced death.Other innocents suffered as well. In the wake of the fighting, Soviet authorities deported hundreds of thousands of Korean rice farmers from the Ussuri region to Kazakhstan, aiming to eradicate Korean settlements that Japanese spies had allegedly exploited.

The Changkufeng clash indirectly hampered Japan's Wuhan offensive, a massive push to subdue China. The influx of troops and supplies for this campaign was briefly disrupted by the border flare-up. Notably, Kwantung Army's 2nd Air Group, slated for Wuhan, was retained due to the Soviet threat. Chiang Kai-shek's drastic measure, breaching the Yellow River dikes to flood Japanese advance routes—further delayed the assault. By October 25, 1938, when Japanese forces captured Hankow, Chiang had relocated his capital to distant Chungking. Paradoxically, Wuhan's fall cut rail links from Canton inland, heightening Chiang's reliance on Soviet aid routed overland and by air from Central Asia. Japan secured a tactical win but missed the decisive blow; Chinese resistance persisted, pinning down a million Japanese troops in occupation duties.

What was the true significance of Changkufeng? For General Koiso Suetaka and the 19th Division, it evoked a mix of bitterness and pride. Those eager for combat got their share, though not on their terms. To veterans mourning fallen comrades on those desolate slopes, it might have felt like senseless tragedy. Yet, they fought valiantly under dire conditions, holding firm until a retreat that blended humiliation with imperial praise, a bittersweet inheritance. For the Red Army, it marked a crucial trial of resolve amid Stalin's purges. While Shtern's forces didn't shine brilliantly, they acquitted themselves well in adversity. The U.S. military attaché in Moscow observed that any purge-related inefficiencies had been surmounted, praising the Red Army's valor, reliability, and equipment. His counterpart in China, Colonel Joseph Stilwell, put it bluntly: the Soviets "appeared to advantage," urging skeptics to rethink notions of a weakened Red Army. Yet, by World War II's eve, many British, French, German, and Japanese leaders still dismissed it as a "paper tiger."

Soviet leaders appeared content, promoting Shtern to command the Transbaikal Military District and colonel general by 1940, while honoring "Heroes of Lake Khasan" with medals. In a fiery November 7, 1938, speech, Marshal Kliment Voroshilov warned that future incursions would prom...
