The transportation of materials for China's war of resistance can only rely on land and international transportation. At that time, the Northwest International Transportation Line from the Soviet Union to Xi'an via Xinjiang was very limited due to the 4,000-kilometer long route and harsh environment. When the Yunnan-Burma Highway was opened to traffic at the end of August 1938, the road conditions were also very bad. As a result, the Guiyue International Communication Line, which connected the ports of Guangdong, Guangxi and Vietnam, became the main channel for obtaining overseas goods at that time.

Yuelan Haiphong Port, is the starting point of the Guiyue international communication line, close to China, with 10,000 tons of giant ships docking, lifting equipment, warehouses are very complete, and railways to China's Guangxi and Yunnan, so it has become an important port for the import and export of China's anti-Japanese war materials.

The supplies in Haiphong were transported to Kunming in Yunnan Province through the Yunnan-Vietnam Railway, and the other was transported to Tongdeng by rail, and then transported to the front and rear of China's War of Resistance against Japanese Aggression through the Guiyue International Communication Line.

It was precisely under this general environment that the Nationalist Government made up its mind to overcome all difficulties and built two more than 1,000-kilometer-long Hunan-Guizhou Railway and Guizhou-Guizhou Railway in Guangxi.

Among them, the Xianggui Railway has been extended to Zhennanguan, which is only a stone's throw away from the Yuelan Railway. However, at the critical moment when it was about to connect, the island army moved south and quickly swept through Southeast Asia, and French India soon became a vassal of the island army, so this international communication line was forced to be interrupted, and the railway had to be suspended.

But if Jiang Haoran can recover the whole territory of Guangxi at this time, Mao Gong can connect this railway in a very short time, and the materials can directly enter Guangxi through the Yuelan Haiphong Port, and then go directly to Henan through the Xianggui Railway and the Pinghan Railway, enter the territory of Henan, and then enter the Ganxin Highway through automobile transportation, and the entire transportation line will be unblocked, which is much faster and smoother than the highway.

Thinking of this, Jiang Haoran suddenly understood the purpose of the two of them's trip, which was simply for this line of communication.

Jiang Haoran said bluntly: "You don't have to think about the Guiyue communication line, it will not be possible to open it in the short term, even if I don't count the casualties to capture Nanning, Yulin and even the entire territory of Guangxi, it is useless, and I have no way to take Hainan Island without a strong navy, as long as Hainan Island is in the hands of the enemy, the first half of the entire transportation line is within the bombing range of the enemy's aircraft." Moreover, our Navy cannot guarantee absolute safety of sea transportation. ”

Chen Chen and Mao Gong were both a little dumbfounded, and after glancing at each other, Chen Chen said without giving up: "But if you don't take Nanning, the island army has the forward base of Nanning Airport, and the entire transportation line in the rear of the Southwest is under his threat, and huge supplies are pouring in, and they don't want to do everything to destroy the traffic?" ”

Jiang Haoran said: "You don't have to worry about this, although we are not effective in attacking, we have more than enough defense." ”

"I don't understand this, isn't it just a matter of troops? At present, a large number of troops in central China are idle there, and they can quickly drive to Guangxi at any time via the Pinghan Railway and the Hunan-Guizhou Railway. ”

Jiang Haoran said with a wry smile: "It's really not a problem of troops, the main thing is that our airfield is not enough, only Baoshan Airport, Wujiaba Airport and Yangtang Airport here are available at the moment, and the distance between Baoshan and Wujiaba is a little remote, almost can only be used for defense, in fact, only Yangtang Airport can provide full firepower, and the island army has more than three large airfields on Hainan Island, as well as Nanning Airport, and there are aircraft carriers that can provide support at any time, so we can only defend in a short time, We can only wait for the situation on the Indochina Peninsula to stabilize and restore the major airfields above as soon as possible, so that we can have absolute strength to contain the air force of the island army, otherwise, I am afraid that if we continue to fight, we will end in failure. ”

Chen Chen said: "Who said that we only have three airports, and there are more than 50 in Yunnan alone, isn't it enough?" ”

In 1922, the Wujiaba Army Playground in Kunming was converted into an aircraft training field, becoming the first airport in Yunnan and the second in China.

From the completion of Wujiaba Airport in 1922 to 1929, Yunnan has built 23 airports, the number of airports has increased by 24 times, which is unique in the history of China's airport construction.

After the outbreak of the Anti-Japanese War, 1.5 million migrant workers were dispatched to build 28 airports, and the total number of airports reached 52, the density was large, which was the first in Asia and rare in the world, and Yunnan became China's most important anti-Japanese air force combat base, and even created a miracle that it took only more than 20 days to build an airport at the earliest.

In 1927, after Long Tian took charge of Yunnan, he was even more fond of developing the province's aviation industry. In addition to purchasing planes from the United States and France, he also ordered the construction of 22 airports one after another, which were completely completed by the Yunnan Provincial Government, and that all counties should be responsible for completing them within a time limit, without funding or compensation, including land occupation, relocation of graves, demolition of houses, recruitment of workers, and so on. All the occupied land, the relocated graves, the demolished houses, and the hired migrant workers were all forced to use them without compensation. It can also be seen from this that the sweat and painstaking efforts of the Chinese people for this war are really admirable.

Jiang Haoran said with a smile: "I'm talking about airfields that can be used for jet fighters to take off and land, in the past six months, the island army has received assistance from the German army, and the strength of the air force has been greatly enhanced, and most of the aid we have received from the allies are actually transport planes, and the current Central China region is still the main direction of our defense, and there can only be so many that can be transferred to Guangxi, and it is simply impossible to reach the strength to compete with the island army for air supremacy." ”

Chen Chen bowed his head and sighed in frustration, and the Mao worker was obviously anxious, and said, "Then the general seat, how can we solve this transportation bottleneck now?" ”

Jiang Haoran sighed and said: "There is no other way, the only way is to quickly build the Yunnan-Burma Railway." ”

Although the construction of the Yunnan-Burma Railway began in 1938, it was forced to stop construction as the island army invaded western Yunnan, in fact, the total length of more than 900 kilometers of the railway was only half repaired, and the expeditionary force stabilized the situation in Burma, and continued to start construction, but until now, there are still more than 100 kilometers not completed.

A railway of more than 100 kilometers, even if there are sufficient materials and personnel, it is difficult to complete it in a short time, especially under the complex geographical conditions of the Yunnan-Myanmar border.

Seeing that Jiang Haoran said it so firmly, the two of them were completely out of line, so they could only overcome the current difficulties and find a way to build the Yunnan-Burma Railway as soon as possible.

However, Jiang Haoran still gave them a little hope, when the situation in the Indochina Peninsula settles down, the first thing will be to resume the construction of the airport, and when the construction of land aviation is completed and enough to ensure the safety of the nearby sea areas, they can consider opening this sea transportation line, and a small amount of materials can enter Yunnan through the Yunnan-Vietnam Railway, which can also relieve a little pressure.
