~April to June 1941 (Transpacific War, China Theatre): The mountains are high and the Emperor far away.
April 1941: With the Gaige Hubei Army Group under General Sun Li-jen, consisting of the Gaige Fourth, Sixth, Ninth and CW Eighth Armies, falling back toward Chongqing, General Hisaichi Terauchi in command of the Japanese Northern Army Group detaches the Fifth and First Armoured Armies to drive on Shaoyang.
April 1941: The trapped CW Second and Gaige Third Armies launch a determined attack attempting to break out of the Shaoxing pocket.
April 1941: With the CW now bombing US cities, IJAAF, IJNAF and USAAC bombers, primarily B-17s from Formosa begin attacking Hong Kong and Guangzhou. These raids inflict heavy civilian casualties.
April 1941: General Renya Mutaguchi in command of the Japanese Central Army Group splits his forces. Seventh and Ninth Armies are in to hold the Gaige First and Tenth Armies in place at Nanchung, while the Fourth, Tenth and Third Armoured Armies are to launch an attack on the Fifth Army with the aim of out flanking and encircling the Gaige positions. His plan achieves rapid success as the Fifth Army disintegrates under the onslaught.
April 1941: Yao troops execute 431 CW and Gaige prisoners at Sashi.
April 1941: The Japanese force at Fuzhou is withdrawn, having suffered heavy losses.
April 1941: The Japanese halt the pursuit of the Gaige Tenth Army to concentrate on the destruction of the CW Second and Gaige Third Armies. This allows the Tenth Army, reinforced by CW troops, to form a defensive position around Qu Xian and Lishui.
April 1941: With situation rapidly deteriorating and having suffered massive equipment losses, the CW begins a massive supply operation across the Hengduan Mountains via the Burma Road. Included in the equipment shipped are Matilda tanks, making their first appearance in the Chinese theatre.
April 1941: The Gaige troops around Nanchung are encircled by Mutaguchi's Central Army Group, leaving nearly 400,000 Gaige troops isolated.
May 1941: Unable to break out of the Shaoxing pocket and with their supply situation desperate, the CW Second and Gaige Third Armies surrender yielding 300,000 prisoners to the Japanese.
May 1941: The Japanese Northern Army Group launches an attack to take Chongqing. Sun Li-jen's dug in Hubei Army Group however holds his position. The lightly armoured Japanese Chi-Ha medium and Ke-Ni light tanks suffer particularly heavy losses to Li-jen's Matilda tanks, with only the Chi-Ho's 75mm guns able to deal with them.
May 1941: With his troops demoralised and exhausted, Gaige General Lin Biao surrenders the Nanchung pocket. With the Gaige in full retreat, Mutaguchi hands these to his Yao allies. Some 30,000 will die on the march to Nanjing.
May 1941: The Japanese Fifth and First Armoured Armies under General Hitoshi Imamura take Shaoyang. The remaining Gaige defenders are now in full retreat and Imamura continues his drive into Guangxi province facing little resistance.
May 1941: Ji'an falls to Mutaguchi's rapidly advancing Central Army Group. By now there is little in the way of the Japanese advance on the Gaige capital.
May 1941: The Japanese Southern Army Group resumes its offensive, launching an attack on the Qu Xian/Lishui line. However the respite due to the reduction of the Shaoxing pocket has allowed the Tenth and newly formed Twelfth Armies to create a formidable defensive position.
June 1941: The Japanese breakthrough the Qu Xian/Lishui line. However both sides have suffered heavy casualties. Nonetheless, the Gaige Tenth and Twelfth Armies are forced to retreat back deep into Fujian province.
June 1941: The French agree to halt the flow of supplies to the Gaige through Indochina.
June 1941: Gangzhou falls to the Japanese. However the Central Army Group is now over extended and Mutaguchi calls a halt to the advance to allow his forces to rest and resupply.
June 1941: With resistance to the Japanese advance crumbling and the Pacific Alliance bombing of Guangzhou and Hong Kong growing increasingly effective, Gaige Grand Chancellor Zhou Enlai orders the Gaige fleet to withdraw to Singapore. Covered by Mustang fighters from Hainan and Malaya, the fleet under Admiral Chen Shaokuan makes are daring dash and despite suffering damage from Japanese aircraft based at Cam Ranh, arrives safely in Singapore. The ships are immediately dispatched to India for a refit to bring their radar and fire control to modern standards, along with improvements to their anti aircraft batteries.
June 1941: Guilin falls to the advancing Japanese Fifth and First Armoured Armies. By now, with the exception of Li-jen's forces around Chongqing, the demoralised Gaige forces are in full retreat, falling back into Guangdong province.
June 1941: With losses rapidly mounting, Terauchi calls off the attack on Chongqing. Sun Li-jen immediately begins further strengthening his position.
June 1941: Zhou Enlai orders the remaining Gaige and CW forces to fall back and concentrate on the defence of Guangdong.
