One day is not a long time, but a lot can be done, at least the troops to build a civil fortification is enough, although it is not realistic to build a semi-permanent fortification in a short time, but with this civil fortification defense line, coupled with the unique geographical environment of Lashio, Jiang Haoran believes that it is no problem to hold on for ten days and a half months.

Speaking of the geographical location of Lashio, we have to explain the terrain of the entire Burma, which is also related to the final way out of the six divisions of the Japanese army in northern Burma.

Myanmar is located in the western part of the Indochina Peninsula, located between 10 degrees north latitude and 28 degrees north latitude and 92 degrees east longitude to 101 degrees, adjacent to Tibet and Yunnan in the northeast, India and Bangladesh in the northwest, Laos and Thailand in the southeast, the Bay of Bengal in the west, and the Andaman Sea in the south.

Myanmar is located in the center of "Sanya", which is a transportation hub connecting South Asia and Southeast Asia, with direct access to Australia in the southeast and Europe through India in the west. Some people describe Myanmar depicted on the map as looking like a fascinating diamond vertically and a peacock with an open screen horizontally.

It is slender and narrow in the south, 2,090 kilometers long from north to south, and 925 kilometers wide from east to west. The land border is 5,858 kilometers long, and the coastline is 3,200 kilometers long. Including a number of coastal islands, Myanmar has a total area of 676581 square kilometres, about the size of Yunnan, Guizhou and Chongqing in China. that

The main feature of Myanmar's landform is that it is surrounded by mountains on three sides, with high mountains or plateaus in the east, north and west, and valleys and delta plains in the center and south. The terrain is high in the north and low in the south, and is dominated by mountains, plateaus and hills. There are three parallel mountain ranges running from north to south, namely the Western Mountains, the Bago Ranges and the Shan State Plateau.

The Rakhine Mountains in the west are Himalayas that extend to the south and have quite a few tall peaks. The northernmost of them, the Kaikabo Peak, is 5,881 meters high, covered with snow all year round, is the highest peak in Myanmar and the highest mountain in Southeast Asia, known as the "Roof of Indochina". About two-thirds of the country's territory is an undulating plateau with a semi-average altitude of more than 1,800 meters, such as the Saramati Mountains on the border between Myanmar and India, with an altitude of more than 3,826 meters. The central mountain range is crossed by the Irrawaddy River to form two parts in the north and south, and the peaks are generally lower than those of the western mountain range, the highest peak is the famous extinct volcano Boba Mountain in the central arid region. The southern part of the Central Range is the Ayeyarwady River valley between the western mountains and the Shan State Plateau in the east.

The Shan State Plateau in the northeast is 500 kilometers long from north to south, 280-450 kilometers wide from east to west, and the average altitude is 900~1000 meters. The highest peak of the plateau is southeast of Lashio, with an altitude of 2,673 meters. The mountainous area of the entire plateau accounts for 70% of the mountainous area, and there are many valleys and basins in between. Wide in the north and narrow in the south, the mountain extends to the south, connecting with the easternmost part of Myanmar, the Devin Range, between the Salween and Mekong rivers, and approaching the equator. If the shape of Myanmar is compared to a kite, the narrow southern part is like the long line of the kite.

Lashio is located at the connection point between the line and the kite, out of the field area of Lashio for more than ten miles, and the terrain has been low from here to the south, which means that the Japanese army has been attacking from the back all the way.

And to the west, out of Ruigu to the south, is the central mountain range of Myanmar, lofty mountains, ravines are innumerable, if you want to climb from here, it is almost impossible, let alone the east, hundreds of kilometers of the Shan State Plateau, the Year of the Ox and the month of the horse can not be turned over.

Therefore, Jiang Haoran is not completely unsure of these seven divisions in Lashio, the geographical advantage can make up for the lack of troops, and they are not short of any materials, the Japanese army's hoarding of materials in Lashio is enough for them to eat and drink, light and heavy machine gun bullets, artillery shells are also sufficient, what is missing is the helicopter equipped with rockets, missiles, of course, and AK47 and the Japanese bullets do not match, but these can be guaranteed by airdrop, although the fighters of the Sino-Mirian coalition are seriously insufficient, but there are many transport aircraft, It may not be possible to control air supremacy during the day, but at night the Japanese troops can only stare dryly.

From early in the morning, the entire 30-mile area of Lashio was in full swing, the troops on the defensive line naturally stepped up to build fortifications, and the reserves all drove into the nearby mountains and forests to cut wood, Burma is full of jungles, all kinds of big trees, as long as you have manpower to transport, it is not a problem to cut down as much.

In the absence of reinforced concrete, these trees are undoubtedly the main material for the construction of fortifications, and they are also the best materials, and several layers of logs are paved to block heavy shells and aerial bombs, but small-caliber artillery is basically no problem.

The greatest threat to the expeditionary force at this time was still the 1st Guards Division in the south, so all the felled trees were transported to the south and used to their best first.

In order to prevent the Japanese air attack, hundreds of helicopters all flew into the Shan Plateau in the east, and the jungle was the best cover, even the Japanese reconnaissance planes could not find their traces.

The common people in Lashio, the old, the young, and the weak, were also resettled here, and the young and middle-aged became logistics troops, and as the Burmese army in Aung San transported supplies and transported the wounded, they were familiar with the terrain, and they were undoubtedly good candidates for this job.

Before eight o'clock, enemy planes, fighters, and bombers appeared in the sky, and the expeditionary force on the city of Lashio and the defense line carried out a frantic wreaking havoc, tossing for nearly an hour before leaving, causing casualties on the defense line to be as high as more than 1,000 people, and the city of Lashio was even more miserable, with the casualties of soldiers and civilians approaching 2,000, and there was hardly a complete building in the entire Lashio.

The flight team of the Sino-Mimegian coalition can no longer compete with the Japanese army for air supremacy, the Japanese planes were dispatched too early, and the troops have not yet had time to set up anti-aircraft firepower.

In order to prevent the enemy from attacking again and as soon as the enemy's planes left, Jiang Haoran immediately ordered the troops to set up anti-aircraft firepower, and also turned out a batch of anti-aircraft machine guns and machine guns that had not yet opened the oil seals from the Japanese army's supplies, and ordered the troops to quickly find suitable high ground and erect them.

Since the advent of the expeditionary force helicopter, the Japanese army has strengthened its air defense forces, such as anti-aircraft machine guns and machine guns, which are all key targets for destruction, so these supplementary weapons must be indispensable in the materials, and the Japanese army probably never dreamed that these would be cheap Jiang Haoran.

Jiang Haoran has always paid attention to supporting firepower, and the expeditionary force is also accepting British and Minian equipment, and he doesn't need to spend a penny, he knows this kind of generous thing too well, every battalion is equipped with a machine gun company, each regiment has an anti-aircraft company, and light and heavy machine guns are even more equipped to the squad, with these anti-aircraft firepower plus these of the Japanese army, it is completely possible to arrange a dense air defense network, although it cannot pose a fatal threat to the Japanese aircraft, but it is not so easy for them to easily strafe at low altitude and dive bombing.
