After He Jianye finished the arrangement, it was already completely dark, and every mobilized unit began to go to their own defense location with torches, and Wanshou Palace, Sanjiangkou, Dajiangkou and Xishan already had troops stationed, just to temporarily strengthen the defense! However, the four battalions heading to Xinjian and Niuhang had to cross the Zhongshan Bridge with their equipment and walk nearly ten kilometers in the dark to reach it, and now Niuhang and Xinjian are the headquarters of the 32nd Army; Army commander Song Kentang is already sending reinforcements to reinforce the Tujiabu area......

"Army commander, Fu Liping, commander of the 142nd Division, called, the Tujiabu position was continuously bombarded by the devil's heavy artillery, and there were heavy casualties; The entire division has already suffered more than half of the casualties, and it is asking for reinforcements! The staff officer took the telegram and reported loudly,

"Hell, the devil hasn't started to cross the river yet? Fu Liping can't stand it? ordered the 141st Division of Tang Yongliang to quickly assemble and station in the second-line position, if the 142nd Division could not stop it, it would give the devils a half-crossing attack; Devils must not be allowed to cross the river! Song Kentang ordered,

"Commander, in that case, there will only be troops directly under the military department in the area of Niu Xing and Xinjian; Isn't it too risky? The 139th Division is still in the Anyi area and is the reserve of the whole group army; The staff officer reminded,

"I can't manage it now, if the devil's 101st Division wants to cross the river, it must leave enough corpses! Relying on shells wants me to give up the line of defense, a dog's dream! Song Kentang scolded,

"Army commander, Nanchang garrison commander He Jianye called;" Another staff officer handed over a telegram from the Nanchang Garrison Command;

"Hehe, He Jianye came with four battalions, and half of his troops came over to reinforce him; You can arrive at the new Wagyu Restaurant before dawn! So that we don't have to defend these two places; Order: The military headquarters moved forward, just two kilometers behind the 141st Division! Tell Tang Yongliang that I am behind him! Song Kentang said,

At 19 o'clock, after destroying most of the positions of the Nationalist army, the Japanese began to kill and injure the living forces of the Nationalist army. Chengtian's artillery group fired poison gas shells as planned to cover the infantry crossing the river.

"Cough, cough, cough" On the Xiushui defense line, the brothers who survived the shelling of the devils fell into the devastation of the Japanese poison gas, and in the last 10 minutes of preparation from 19:20 to 30, the Japanese army fired more than 3,000 poison gas bombs. Immediately afterwards, the Japanese field gas team released 15,000 medium-sized gas canisters on the 12-kilometer offensive front, of which 10,000 were released from the 106th Division's attack point.

Poison gas bombs are artillery shells that form poison gas when they explode. The gas pump is a large iron barrel, and after the start of the fight, the poison gas will be dispersed to the position of the national army in large quantities, which is more powerful than the poison gas shells. The Japanese army also used a large amount of poison gas in the previous Battle of Songhu, Xuzhou, and Wuhan, but it was definitely not so frustrating this time, and it was completely to exterminate the defenders; For a time, almost all the front-line positions of the national army were shrouded in poison gas. The 2-kilometer depth of the Chinese defenders' positions in the Xiushui River was completely enveloped in poison gas. Countless soldiers of the national army rolled in pain in the gas-shrouded position, completely losing their combat effectiveness, and many brothers suffocated to death. The officers and soldiers on the position were almost 100% poisoned!

At this time, the defense line of the national army was basically destroyed, the positions were basically all blown up, and there were fragments of wood and stones everywhere, and the power of the Japanese heavy artillery was fully revealed!

The devils began to attack near dusk, and they did not plan to stop when it got dark; The large-scale artillery coverage stopped, and the heavy artillery of the devil's 100mm or more also stopped, but the shelling of the 75mm mountain artillery and field artillery did not stop, and the 106th and 101st divisions of the devil took advantage of the dark night, put on gas masks, and came towards the south bank of Xiushui under the cover of poison gas and shells......

In particular, Junrokuro Matsuura's 106th Division crossed at 19:30 from Aicheng and Qiujin, west of Yongxiu, under the cover of fire.

The Japanese officers and men of the 106th Division, wearing gas masks, rushed to the opposite shore with more than 80 boats. Guarding this line was the 49th Army of the Northeast Army and the 79th Army of the Central Army, when the defense line of the Nationalist Army was basically destroyed, and the surviving defenders used rifles, machine guns, and grenades to shoot at the Japanese troops who rushed to the crossing in the poison gas, and the Japanese troops retreated back after paying hundreds of casualties and stopped the assault.

The bunkers and fortifications on the shore were furious in this round of shooting, and the devils were the same old way, and the large-scale shelling of heavy artillery began again, destroying the firepower of the national army one by one in the violent explosions. Under the attack of 300 heavy artillery of the Japanese army, the defending national army suffered heavy casualties, and after a night of fierce fighting at 7 a.m. on March 21, all the positions of the national army in the main attack direction of the 106th Division were broken through.

At this time, Wang Lingyun, the commander of the 76th Division, had been poisoned, and under his leadership, the 76th Division and the 105th Division next to it launched a comprehensive counterattack against the devils who had just landed. The devils used the telephone to call for artillery support nearby, and the counterattacking national troops suffered heavy casualties......

At 7:40 on the 21st, the 106th Division crossed the Xiushui River, which was about 300 meters wide and flowed at a speed of about 2 meters per second after the rain. The Chinese and Japanese armies engaged in a fierce exchange of fire around the beachhead, and the poorly equipped defenders shouted loudly to kill the devils and fell under the heavy machine guns of the Japanese army one by one; The 106th Division then used heavy artillery and air force as cover, and adopted the tactics of central defense and flank advance in an attempt to outflank the rear of the two divisions. After several hours of fierce fighting, the Japanese repelled all the counterattacks of these two divisions, and then launched a counter-attack. In this battle, the Northeast Army and the Central Army also used all their strength, and at this time, all the casualties of the participating troops exceeded 70%, but they could not drive the devils back to the south bank of Xiushui, and their own back roads were still at risk of being outflanked. The 106th Division immediately advanced along the abandonment of the position of the 49th Army, and the 79th Army of the Central Army on the side also withdrew after seeing that the Japanese army was outflanking the rear road. In this way, the line of defense for repairing water lasted about 12 hours. At this time, due to excessive casualties and panic among the front-line commanders, the 49th Army of the Northeast Army Liu Duoquan was chaotic when retreating, and there was a situation of defeat.

At the same time as the 106th Division forced the crossing, Saito Yaheita's 101st Division began to cross the river from Tujiabu at 20 o'clock. Originally, the troops on the front line of Tujiabu were only defended by one division of Fu Liping's 142nd Division. It was much weaker than the breakthrough point chosen by the 106th Division, and the combat effectiveness of the Jin army was not strong, and the 142nd Division suffered for 2 hours under the intensive shelling of the Japanese heavy artillery, with huge casualties and all the front-line positions destroyed.

When the 101st Division was strong, most of the 142nd Division had lost the ability to resist, but fortunately, the 141st Division arrived in time, and the 142nd Division cooperated with the 141st Division to launch repeated battles in Tujiabu after collecting the remnants and sorting out the equipment!

At the same time as the 101st and 106th Divisions were forcibly crossing, the tank group was also forcibly crossing. However, it was much more difficult for the tanks to cross the river, and the 3rd Independent Engineer Wing, under the cover of artillery fire, had already built a pontoon bridge over the repaired water, and Ishii Hiroyoshi Daisa, with 135 tanks and dozens of armored vehicles, braved the bullets and grenades of the defenders to charge; Defending this was a division of the 79th Army, which, very tenacious, and without heavy weapons, fired heavily with rifles and machine guns at the tanks crossing the river, killing the exposed tanks and several tanks falling into the Xiushui River in confusion. After a night of forced crossing, more than 130 tanks and dozens of armored vehicles of the tank group all crossed the Xiushui River at 8 a.m. on the 21st, accompanied by a brigade of infantry and two squadrons of tank maintenance engineers.
