On May 19, 1938, after the Japanese army occupied Xuzhou, the Japanese army base camp believed that the Battle of Xuzhou was basically over. In order to expand the results of the battle, X made the following deployments:

1 Expand the results of the Battle of Xuzhou, and roughly stop at the east of the connection line of Lanfeng, Guide (i.e., Shangqiu), Yongcheng, and Mengcheng.

"2 The commander of the Central China Dispatch Army should make the troops participating in the Battle of Xuzhou continue to sweep along the Jinpu Line and must move to the area south of the Huai River (inclusive) as soon as possible. The 13th Division could be deployed on the banks of the Huai River west of Bengbu, and it was scheduled to be transferred to the 2nd Army.

"The commander of the 3rd North China Front Army should follow the transfer of troops from Central China and deploy about 2 divisions of the 2nd Army as the backbone of the troops along the Jinpu line south of Xuzhou to the Huai River."

After receiving the instructions, the "Central China Dispatch Army" immediately ordered the 3rd Division to assemble near Fuliji, the 5th Division to assemble near Bengbu, and the 13th Division to advance towards Mengcheng. As early as the night of the 19th when the "North China Front" entered Xuzhou, it had already issued a pursuit order to expand the results of the battle to the west, and ordered the 2nd Army to enter and occupy Guide.

Just two days ago, on May 17, the 14th Division of the First Army was clearly required to cut off the section from Guide to Lanfeng on the Longhai Railway, and occupy Guide to achieve the encirclement of the main force near Xuzhou on all sides. The main force of the 14th Division was still in the process of crossing the river, while the cavalry wing of the 14th Division and a squadron of light armored vehicles attached to it had advanced to the Longhai Railway between Guide (Shangqiu) and Lanfeng (Lankao). The Japanese army took advantage of the speed advantage of cavalry and light armored squadrons, and wanted to attack in the direction of Longhai Road with fast troops first, disrupting the deployment of **.

The battle deployment and orders in the First Theater were soon issued to the following, planning to deploy several elite armies on the Longhai Line and its key points, and planning to assemble the 74th Army, the 64th Army and the 8th Army near Guide to protect the safety of the retreat route west of Xuzhou, and waiting for an opportunity to respond to the retreat of the Xuzhou troops and defend against possible invading enemies near Lanfeng. The 71st Army and the 27th Army defended the vicinity of Lanfeng, the 20th Army occupied Kaocheng and along the Yellow River, and the 106th Division of the Northeast Army System was responsible for the garrison of the Longhai Road between Minquan and Lanfeng.

At this moment, the Japanese assault force on the Longhai Line, in the final analysis, is a cavalry wing and a subordinate light armored vehicle unit, and the main force of the 14th Division is still continuing to cross the river.

First, the deployment plan on paper is very good, but only the 106th Division is about to complete the transportation, and only one brigade of Song Xilian's 71st Army (the 262nd Brigade of the 88th Division) has just occupied the key point of Lanfeng, and the main force of the army is still continuing to urgently transport. And the other main force that coordinated the defense of Lanfeng, Gui Yongqing's 27th Army, could not even see a shadow, and it was also still being transported on the train. The 106th Division, which served as a garrison along the Longhai Road, had not yet been deployed and prepared.

The 71st Army, the 74th Army, and the 27th Army were all units that had been reorganized after retreating from the Battle of Nanjing, and the rest time of the troops was less than five months, which also included the replenishment of weapons, the distribution of officers, and the replenishment of recruits. Zhang Wei's reserve battalion, a battalion can have a veteran of an old independent company, plus the transferred sergeants, for the time being, it can be counted as a veteran of one and a half companies, and the troops that participated in the war in Nanjing are the worst, one battalion is only half a company of veterans, and the situation is relatively good, not much stronger than Zhang Wei's reserve battalion.

The only way for the squadron to gain superiority is to win by numbers and transfer more troops! to call up more participating units!

Before the real battle began, the gap had already widened.

In the early morning of May 17, as usual, on the Longhai Line, there were occasional troop carriers painted with large white letters passing through this transportation hub, and soldiers patrolling could be seen on the railway line from time to time, and the characteristic fog of the early morning had not yet dissipated, providing excellent cover for the lurkers hiding in the shadows.

A few hours ago, the 14th Wing of the 59th Division, which crossed the river first, contacted the division commander Tu Feiyuan after making contact with the cavalry wing of the 14th Division, and just as the commander of the 59th Wing had hoped, the division agreed to the 59th Wing's application for attack, and when the division had not yet completed the crossing of the river, the 59th Wing and the cavalry wing cooperated and launched an attack on the Longhai Railway in two columns. At this time, the deployment of the first squadron has not been completed, many villages and towns on both sides of the Longhai Road and key points are not garrisoned, the 106th Division responsible for guarding the Longhai Railway has been transported by train for the past two days, and a division is responsible for the vigilance of the main road section, and the strength is slightly stretched, which also shows that the first side wants to fight the Japanese army on the periphery of the railway.

The 59th Wing, which had obtained permission, occupied the important stronghold on the north side of the Longhai Line a few hours ago, and used it as a base to advance forward, sending forward troops to control the Longhai Line.

The 3rd Brigade of the 59th Wing, carrying four wing guns and radio stations, first got in touch with the 18th Cavalry Wing that had previously assaulted, and then advanced to the side of the Longhai Line under the cover of the main force of the Wing, the soldiers of the 3rd Brigade deployed their troops under the command of the captain, and the 3rd Brigade took advantage of the dark night and fog to advance, digging a small number of improvised fortifications overnight, plus the nearby hills and weeds formed a concealment department, and finally let the railway line lie right in front of its own muzzle, except for the machine guns and rifles of the brigade. There were also a dozen grenadiers and four 75-mm mountain guns, two 70-mm 92 infantry guns.

On the south side of the railway, the 18th Cavalry Wing, which was the first to launch the assault, determined the location of the 3rd Brigade of the 59th Wing through the radio, and about three squadrons of horsemen and five Type 94 cavalry chariots arrived at the position after the 3rd Brigade of the 59th Wing, ready to respond at any time.

With the sound of a whistle from the train, the first batch of military trains on the 17th began to depart from Guide and move west on Longhai Road, loaded with two infantry battalions of the 106th Division and a small amount of supplies, and the Chinese soldiers in the dark carriages were basically asleep, in the carriages, there was basically no need to be alerted, only individual company and platoon commanders were talking in low voices, and the topics of conversation seemed to have nothing to do with the war situation.

In the entire train, only a few train drivers in the head of the traction locomotive and a deputy battalion commander of the 106th Division maintained a high degree of vigilance, and the news of the Japanese army's appearance on Longhai Road was no secret for a long time, and the conductor was even more nervous than the soldiers.

The Japanese soldiers hidden on both flanks heard the sound of the whistle, all raised their guns in their hands, and aimed at the middle ** column in the concealed place, the friction of the wheels and the rails was getting closer and closer, and the captain of the third brigade wanted to open fire at a distance of 200 meters, but a newly replenished soldier of the Japanese army below actually pulled the trigger first out of panic.

Even if there is the noise of the train, the crisp sound of gunfire is still so harsh in the early morning, and the conductor who has been on high alert reacted quickly, desperately pulling the iron handle of the brakes, and the deputy battalion commander on the side understood very well that this was the Japanese army's 38 rifle, and quickly took out the pistol on his waist, and shot out of the window to warn the officers and soldiers in the personnel carrier. The rear car had just been woken up by the inertia of the train's brakes and the sound of gunfire, and the officers began to try to organize the soldiers to prepare for battle, and got off the train to return fire, but it was too late, even if the brakes were in time, but the inertia of the train still made the car continue to move forward, and it had already entered the effective range of the Japanese army.

The Chinese soldiers were greeted by an overwhelming amount of ammunition, rifle and light machine gun bullets of 65 caliber, heavy machine gun shells of 77 caliber, light and heavy grenadier cartridges of 50 mm, plus 70 mm infantry shells and 75 mm of wing mountain artillery shells, which smashed madly on this train that had not yet stopped, and the carriage became a hell on earth, blood and internal organs and stumps, weapons mixed together, and blood flowed out of the gap in the lower edge of the carriage, staining the rails and wheels red.

When the train slowly stopped, the 18th Cavalry Wing on the other side began to open fire on the side, and the two Type 94 bean chariots saw that there was a bargain to fight, and rushed straight out to the train and began to shoot, and the brave Japanese troops advanced under the command of Jun Cao, sweeping away the remaining Chinese soldiers who resisted.

Some of the Chinese soldiers who jumped out of the car and fought back fell in pools of blood, and the remaining people could only rely on the carriage and shoot indiscriminately in all directions, and the faint sound of return fire was close to nothing as the guns were more intense.

"Urgent telegram, the Japanese army in Lanfeng has attacked to the Longhai line, and the two battalions of the 631st Regiment of our 106th Division were attacked by the enemy during the transportation, and most of the more than 1,000 people were martyred. The Department of the Commander of the First Theater of Operations"r
