While German Navy and Island Nation Navy were having a decisive battle on Pacific Ocean, German Army's attack on the Indonesian Islands was also in full swing.
On Sumatra Island, German 11th Army Corps captured Medan, and 7th Area Army of the Island Nation's Army was completely annihilated under German military's Encirclement Offensive. Commander General Seishiro Itagaki dozens of generals below all committed seppuku and committed suicide.
Subsequently, German 11th Army Corps, 3rd Army Corps and 13th Army Corps advanced southeast along Malacca Strait. Fighting with the 14th Area Army of the Island Nation's Army, 2nd Army and 18th Army.
Although 14th Area Army of the Island Nation's Army has strong troops, the 2nd Army and the 18th Army also have several divisions. However, under the attack of the main forces of the three armies German military, Island Nation's Army obviously could not hold on on Sumatra Island and was constantly defeated.
On Java Island, German 12th Army Corps, 4th Army Corps and 16th Army Corps, after solving Island Nation's Army 5th Area Army, defeated Island Nation's Army 4th Army and the 38th Army. Compressed all Island Nation's Army's remaining troops on Java Island to the Batavia front line.
Although 18th Area Army of the Island Nation's Army still has a certain amount of troops, it is almost impossible to withstand the fierce attack of the three armies of German military.
On New Guinea Island, Island Nation's Army 10th Area Army and 31st Army were also defeated by the attacks of German military 22nd Army Corps and 24th Army Corps. Many Island Nation soldiers even hid in the dense virgin forest after being dispersed.
At this time, the development of South Seas was not high. There are vast tracts of primeval forest everywhere. Especially New Guinea Island, except for the developed coast, all the inland is virgin forest occupied by savages. There are poisonous insects, snakes and ants everywhere inside, and it is impossible to survive inside.
It can be said that after German military dispatched eight armies to launch an attack under the full cover of the air force and navy, Southern Army could no longer hold on. A large number of elite troops were defeated and wiped out. The defense zone also continued to fall. It can be said that Southern Army has reached a very critical juncture.
However, even so, General Terauchi Juichi still stayed at Batavia and did not leave here.
Terauchi Juichi General is still waiting for news from the navy. If Combined Fleet can defeat German Navy, it will be able to regain South Seas's sea control. At that time, more reinforcements can even be continuously dispatched from the country to reinforce South Seas. In that case, Southern Army's crisis will be resolved.
However, General Terauchi Juichi may never wait for the victory.
On the afternoon of August 2, Southern Army Headquarters received Telegram from China.
"Your Excellency Commander, emergency Telegram has been sent from China." Lieutenant General Tadaichi Tsukada reported.
"What news? Has the Navy defeated the Germany people?" General Terauchi Juichi asked quickly.
"Your Excellency Commander, the navy failed. Combined Fleet was almost completely wiped out and did not cause any losses to the Germany people." Lieutenant General Tadaichi Tsukada said.
"What? How could this happen?" General Terauchi Juichi was completely stunned. He didn't seem to have expected that this would be the outcome in the end. He was still waiting for victory, but the result was news of failure.
"Your Excellency Commander, the navy has failed. I'm afraid it will be difficult for us to defeat the Germany people." Lieutenant General Tadaichi Tsukada said.
Indeed, Combined Fleet failed miserably, and Southern Army will be fighting alone. At the same time, with the loss of sea control, Island Nation's Mainland can no longer provide support to the Southern Army. If Southern Army wants to continue to hold on in South Seas, it is almost impossible.
General Terauchi Juichi nodded. "Order 18th Area Army, 4th Army and the 38th Army to defend Batavia. Prepare the seaplane and leave here tonight and go to Manila!"
In the case of the navy's disastrous defeat, General Terauchi Juichi knew very well that South Seas's battle situation would further deteriorate. It is almost impossible for them to resist the attack of the three elite armies of German military at Batavia. Therefore, General Terauchi Juichi made a decisive decision to leave here.
"Yes, Your Excellency Commander." Lieutenant General Tadaichi Tsukada immediately went to make arrangements.
On the evening of August 2, General Terauchi Juichi and others left Batavia by seaplane and went to Manila.
It seemed that with the escape of General Terauchi Juichi, the situation of South Seas completely collapsed.
18th Area Army of the Island Nation's Army, 4th Army and the 38th Army held out at Batavia for five days. Under the fierce shelling and bombing of German military, the entire urban area of Batavia was reduced to ruins. But even so, Island Nation's Army still fights to the death.
Finally, after running out of ammunition and food, 18th Area Army of the Island Nation's Army, 4th Army and the remaining troops of the 38th Army, led by their generals, launched a suicidal attack on German military, but were beaten into pieces by German military's intensive firepower.
After Java Island fell into the hands of German military, German military launched an attack on Borneo non-stop.
At the same time, German military's battle on Sumatra Island has also come to an end. 14th Area Army of the Island Nation's Army, the 2nd Army and the 18th Army have been almost wiped out. The remaining troops were just stubbornly resisting, and it was only a matter of time before they were all eliminated.
German military Army Group under the jurisdiction of 3rd Army Corps, 25th Army Corps, under the cover of the navy, crossed the South China Sea, in Luzon Island landed and directly launched an attack on the Philippine Area Army and 34th Corps under the jurisdiction of the Island Nation's Army Southern Army who were entrenched in this area.
Southern Army has not many troops on Philippine Islands, and Philippine Area Army only has one Infantry Division regiment and two independent mixed brigades. 34th Corps also has only two Infantry Division groups and one independent mixed brigade. The total number of these two armies is only over 80,000. With such a small force, it is almost impossible to counter the two armies of German military.
After landing at German 3rd Army Corps, we marched towards Manila with great momentum. Philippine Area Army of the Island Nation's Army and 34th Corps are simply irresistible.
On August 14, most of Manila fell into the hands of German military. Island Nation's Army Southern Army Commander Terauchi Juichi General is not planning to escape this time. Because he knew that Southern Army was defeated miserably and the entire army was about to be annihilated. Even if he escapes back to his homeland, he will still be questioned. Rather than that, it would be better to kill yourself. In this case, it can be regarded as maintaining one's honor.
Therefore, on the afternoon of August 14, General Terauchi Juichi committed suicide by committing seppuku at Southern Army Headquarters. Subsequently, Lieutenant General Tadaichi Tsukada, Chief of Staff, also committed seppuku.
That evening, all Manila fell.
By August 20, all Island Nation's Army Netherlands East Indies Expeditionary Army and 37th Army who persisted in fighting at Borneo were wiped out. The entire South Seas fell into the hands of German military.
