There is no problem with the historical prototype of the Yamazaki Brigade being the Okazaki Brigade in the Battle of Sekigaga. Moreover, not only did the Okazaki Brigade change its name to the Yamazaki Brigade, which appeared in "Bright Sword", but also reflected in other TV dramas with revolutionary historical themes, such as the biographical TV series of Peng and Liu, and this battle also appeared, and it was also Chen Geng who was in charge of the front line command, all of which were in the case that the 772nd Regiment attacked many times and still could not break through the Japanese positions, Chen Geng ordered the independent regiment to be replaced and destroyed the Japanese army in one fell swoop.
In fact, this has a lot to do with the Japanese army's tactics. Compared with the Chinese army at that time, the Japanese army had two basic characteristics in the war of aggression against China, the first is that the strength of the japanese army has always been insufficient, and it is rare that the Japanese army uses more troops than the Chinese army in the same battlefield, and the second is that the equipment level and firepower configuration of the Japanese army are far stronger than those of the Chinese army, whether it is machine guns, cavalry, or cars, or artillery. This determined that even if the Japanese army had a small force, as long as it was equipped with sufficient fire support weapons, it would dare to take the initiative to attack the Chinese army, which was far more numerous than its own.
And in even large-scale battles such as the Battle of Xuzhou, the Japanese army dared to take on the task of attacking or flanking the Chinese army in a roundabout attack or flank in the secondary direction, with a small force of 200 or 300 people, and often played an unexpected role. For example, in the Battle of Changde, a division of the Nationalist Seventy-third Army also chose to retreat immediately when it found that a small group of Japanese troops of two or three hundred people had swerved back to its flank, because the Nationalist army judged that it was likely to be surrounded. If there is no further retreat, once the Favorable Terrain is occupied by the Japanese Army, the retreat route of the Nationalist army will be cut off by relying on the danger.
Not only did the Japanese army dare to use a small group of troops with cavalry and artillery to form a mixed reinforcement brigade to take on this tactical roundabout attack task when dealing with the Chinese army, but in fact, even on the Indian-Burmese battlefield, facing the British army and the Chinese expeditionary force, the Japanese army also dared to adopt this method of warfare, and the effect was good, almost can be said to be invincible. Not to mention a brigade of five or six hundred men, that is, a squadron of two or three hundred men, as long as it has seized favorable terrain, it can often block the retreat of the Nationalist army with machine guns and artillery fire, and then continue to reinforce.
For example, in the Battle of Ren'anqiang, when more than 7,000 British troops were retreating, the Japanese army of about 2,000 people who were attacked in a roundabout way controlled the bridgehead, cutting off the way for the British army to continue to retreat to India, and the 7,000 British troops suddenly thought that they were surrounded by Japanese troops, and even began to consider surrendering. In a hurry, the British commander Slim asked Stilwell and the Chinese Expeditionary Force for help, and when Sun Liren, the new thirty-eighth division of the Expeditionary Force, was ordered to break the siege, it was actually only a regiment of Liu Fangwu who was sent out, and soon repelled the Japanese army and rescued the British army, and Sun Liren was also internationally renowned and became a Chinese general that both Britain and the United States liked.
On the Chinese battlefield, the Eighth Route Army is undoubtedly the worst-equipped army, although the morale is high, the tactical quality is also the strongest in the Chinese army at that time, but after all, the level of equipment is too far from the Japanese army, so the Japanese army often uses a small unit of two or three hundred people in the sweeping operation, as long as it carries a part of the infantry artillery, mortars and heavy machine guns, it also dares to go deep into the anti-Japanese base area to sweep, and the Japanese army is often faced with far more people than its own Eighth Route Army at this time. Moreover, once surrounded by Chinese troops, the Japanese could immediately transport reinforcements from nearby strongholds by car and send aircraft to bomb if necessary.
We often criticize the Nationalist army for mistakenly adopting the tactic of refueling successively in the Battle of Songhu, but in fact, the Japanese army used almost all the refueling tactics on the Battlefield in China, and almost every attack was in this way. Even in a relatively large-scale battle, the Japanese army dispatched tens of thousands of people or even hundreds of thousands of people, but also scattered in multiple tactical directions, often the situation is that a single wing of the Japanese army can crush a division or even an army of the National Army, and even if the National Army surrounds a japanese company with several armies, the Japanese army can also rely on danger to hold firm, wait for help, and finally break through with the support of the receiving troops.
