The First World War was a brutal war, the trenches on both sides caused the battlefield environment to be extremely harsh, the bad weather made the trenches extremely bad, and the damp trenches made many soldiers replace the trench feet.

Trench foot is also known as "trench foot" and "trench foot". It is a foot injury caused by standing in a damp and cold trench for a long time.

The affected limb is pale, chilly, paresthesias, and has a cold sensation. Thereafter, the affected limb becomes red, warm, and edematous, painful, and paresthesical, and can be exacerbated by heat or by placing the affected limb in a low-hanging area. Later, blisters or blood blisters may appear in the affected limb, and bleeding may occur in the intradermal or subcutaneous tissues. This stage can last for several days, and in severe cases gangrene may occur, and it can also be accompanied by lymphangitis, cellulitis, and thrombophlebitis. During the congestion phase, there may be mild fever, palpitations, and occasionally temporary proteinuria and other systemic symptoms.

Patients with mild and early treatment may recover after the congestion phase, while the rest of the cases will enter the vasospasm phase, where sensitivity to cold is exacerbated and the typical Raynaud's symptoms include increased sweating, chills in the lower extremities, pain, and paresthesias.

In addition to the sufficiency of the trenches, the trenches were full of corpses, and the cold and damp weather made the conditions in the trenches even worse, and various diseases began to breed in the trenches, making many soldiers sick.

And as the temperature warmed, the corpses began to decay rapidly, and the stench was unbearable.

The transportation in the trenches was very inconvenient, which also made medicine and food unable to be transported to the front line in a timely manner, and even more tortured the soldiers in the trenches.

The war also led to the stagnation of production, the destruction of factories and farms, and the creation of many refugees.

However, the main places of war were Belgium and France, and only East Prussia was the only one who encountered the baptism of war in Germany, and with the continuous advance of the German army on the Eastern Front, the battlefield was transferred to Russia, which also made a large number of refugees appear in Russia.

This is the brutal war.

In contrast, the situation on the battlefield in Shandong was much better.

After the armistice, the East China Autonomous Axe evacuated all the people in the war zone and dug a complete trench system.

The trenches of the East China Army have the functions of drainage, rain protection, and many passages to the rear, which keeps the trenches dry, and has a good transportation system, so that the supplies from the rear can be delivered to the front-line soldiers in time.

In addition, the East China Army dug many underground bunkers for soldiers to hide from artillery shelling, and many small basements were dug up in front of them, in which many defensive flamethrowers were placed, forming an invisible and impenetrable line of death.

The trenches are not so well dug, but they are good in terms of defensive function, but they are not as comfortable.

Moreover, the two sides are currently in a state of truce, and in the absence of an exchange of fire, the harsh conditions of the trenches can still be tolerated.

In the spring of 1915, the Anglo-French forces took advantage of the concentration of the main German forces on the eastern front and launched two offensives at Shambany and Adwa. However, due to the old tactics and the lack of strong firepower, the Germans successfully resisted, and their own side suffered heavy casualties.

In April of that year, the Germans counterattacked and used poison gas for the first time, adding to the heavy losses on both sides.

The infamous gas war still happened, and although Xia Jun prepared the gas mask in advance to sell, it was definitely not the result he was willing to see.

The Anglo-French forces quickly purchased gas masks provided by the East China Autonomous Axe, a mask like a wild boar mask that could withstand chemical gases.

In order to resist the poison gas of the German army and save the morale of the front line, the British and French forces had to buy gas masks sold by the East China Autonomous Government at a high price, and placed a large order for gas masks.

The East China Army was also equipped with gas masks in May of that year, and it was a large amount of equipment to prevent the use of chemical gases, and at this time the Entente countries also began to develop chemical gases, which were very likely to be used by the Entente, after all, the Entente is now also the Entente sequence, and the Entente countries can share technology.

At this time, the Entente was supporting Yueben, hoping that Yueben could defeat the East China Army in the Shandong battlefield, and then withdraw to reinforce the European theater.

Such intentions of Britain and France were obviously unrealistic, but they believed that they would have sent troops to reinforce Europe, since they had already sent 200,000 troops to Europe.

As everyone knows, they have no intention of fighting this European war, which is not beneficial to them, and their intention is only to expand their territory.

Xia Jun basically didn't care about the Entente's behavior of supporting Yueben, and now it was difficult for him to ride a tiger with a political axe, and hundreds of thousands of people reinforced the Shandong battlefield, and were besieged by the East China Army on the front line of Longkou, like a turtle in an urn.

He also had some doubts about whether the Shandong battlefield should continue to fight, after all, the situation on the Shandong battlefield was extremely unfavorable to him.

However, the militarists did not admit defeat, believing that the previous defeat was not because the Great Empire was not strong enough, but that it was lagging behind in the use of new weapons, and as long as these new weapons were equipped, they could naturally defeat the Chinese people.

However, as the trench warfare on the European battlefield continued, the confidence of the political axe became more and more shaken.

The East China Army had already formed an encirclement of the Yue Army on land, and hundreds of thousands of people had been besieged by the East China Army in a small corner of Shandong, and if they wanted to attack, they had to first break through the East China Army's trenches.

But retreat is obviously impossible, after all, so many troops and financial resources have been invested in the Shandong battlefield, retreating means admitting defeat, and a reparation has been paid before to seek an armistice.

At this time, the political axe is like a gambler, although the cards are not good, but still have a fluke mentality, and constantly raise the table in order to win a game.

Moreover, he felt that even if they could not break through the defense line of the East China Army, the East China Army would also not be able to break through their defense line, and even if they could not win, they would definitely not be able to lose, as long as the sea line of communication could be guaranteed.

In order to ensure that the political axe could be supported on the Shandong battlefield, the United States even leased their South Carolina-class battleships to Yuben, which is a kind of useless ship, which is somewhat outdated compared to super senseless ships, with a displacement of more than 17,000 tons.

Several U.S. Nevada-class battleships have been launched, and although they are not yet in service, the U.S. Navy can already sell these obsolete and useless ships.

The United States is a country that has no risk of war at all, and the only thing they had to guard against in the past was the United States, but at this time, the United States was fighting with the East China Autonomous Political Axe in the Far East, and it could not threaten the security of the United States at all.

The biggest problem facing the city is the issue of sea supremacy, and the East China Autonomous Government has a large number of submarines and bombers, and it is simply impossible for the East China Autonomous Government to carry out normal sea transportation during the daytime in the coastal waters.

In the event of a war, the only thing Ben could do under the threat of bombers was to transport it at night, but it still faced the danger of being bombed.

Therefore, it is necessary to strengthen the strength of the navy, although these useless ships are estimated to have no effect, but it is a good choice to sell these obsolete warships to the warships, and no country has such a great demand for warships as the one in this country.

After Ben bought those battleships, he immediately began to modify them, and installed a large number of anti-aircraft guns on the battleships.

Although the current anti-aircraft artillery technology is not yet mature, and even 10,000 shells can sink one plane in the European theater, but this is better than nothing, isn't it?

In terms of air defense, the political axe did not completely count on those warships equipped with anti-aircraft guns, but vigorously developed and purchased fighter jets.

Fighter technology has been extended since Germany first put the fighter planes produced by the East China Autonomous Political Axe into the battlefield, and the East China Autonomous Political Axe began to sell fighter planes later.

Thanks to the device of mounting the machine gun in front of the fuselage, the combat surname of the fighter has been unprecedentedly improved, and it is precisely the intention of equipping hundreds of fighters on the Shandong battlefield to block the planes of the East China Air Force.

It turned out that the best means of air defense was aircraft against aircraft, which was confirmed by the great victory of the Luftwaffe, which also provided a viable air defense route for the Luftwaffe.

As one of the Entente powers, it was natural that he was able to obtain technology sharing between Britain and France, so he was very quick to develop their fighters.

Moreover, the United States also began to develop their fighters, although they were inferior to the Eagle 3 fighters manufactured by the East China Aircraft Factory in terms of surname, but they were able to produce well, and most of them were bought by the political axe.

The British and French forces basically did not equip the United States with fighter planes, because the American fighters proved to be very pale and powerless against the German fighters, so they mostly chose the Eagle 3 fighter produced by the East China Aircraft Factory, which is a very fast fighter with very good combat capability.

This kind of aircraft can not be built by the Entente countries, because the engines are not up to the requirements, although they have made the engines on these aircraft in reverse order, but they will not be able to master this advanced engine technology for a while, which involves many aspects, such as mechanical manufacturing, metal smelting, and so on.

Germany had no problem with this, because they could import advanced engines from the East China Autonomous Axe, and they would only need to develop their aircraft based on them.

The most important thing in Shandong's preparations for war was to form an air force unit under the command of the army, and the most important thing was that in terms of fighter planes, the quality was not comparable to the quantity, and this was the strategy of the political axe, striving to bring about qualitative changes by means of quantitative changes.

However, neither Ben nor the Entente countries knew that the East China Aircraft Factory was rapidly developing all kinds of aircraft at this time, and the amount of money invested was greater than that of any other country.

A new all-metal fighter, a new single-wing all-metal heavy armor three-engine tactical bomber, a smart and cheap Mosquito strategic bomber, a fighter, a torpedo plane, a reconnaissance plane...... This series of actions are in the forefront of the country, when the countries are still keen on the development of biplane wooden aircraft, the East China Autonomous Political Axe has realized a large number of equipment and production of monoplane wooden aircraft, and began to develop in the direction of all-metal aircraft.
