Two months before he graduated, the United States entered the war. Carlos Becker wrote: "The road he faces is to go to college, fight and work." Hemingway chose a job. He has a problem with his left eye (he accidentally injured his left eye while practicing boxing, and his vision dropped, so his left eye vision never recovered), so he is not suitable for fighting. 19 17 10 month, he began to work as a trainee reporter in Kansas city's Star, which was one of the best newspapers in the United States at that time. In six months, he interviewed hospitals and police stations, and also learned excellent business knowledge from G G Wellington, an excellent editor of the Star. Hemingway understood for the first time in The Star that style, like life, must be cultivated. Print out the list of famous styles of stars: "use short sentences" and "the first paragraph should be short." Use lively language. Say it positively, not negatively. " Hemingway learned to turn the rules of writing news into literary principles in a relatively short time.

However, the attraction of war attracted Hemingway more and more, and he began his expedition in the second half of May 19 18. Two months ago, he volunteered to go to Italy as a driver of the Red Cross, and only stayed at the front for a week. Late at night on the last day of this week, Hemingway was hit by an Austrian mortar shrapnel while distributing chocolate to Italian soldiers in the village of Fu Salda on the Piavi River in northeast Italy. A soldier next to him died on the spot, and another soldier in front of him was seriously injured. When he dragged the injured soldier to the back, he was hit by a machine gun in the knee again; When they arrived at the shelter, the wounded soldier was already dead. Hemingway got more than 200 shrapnel on his leg, and his left knee was interrupted by a machine gun, so he was forced to have platinum knee surgery. He stayed in a hospital in Milan for three months and had more than a dozen operations. Most of the shrapnel was taken out, and a few shrapnel remained on him until he died. When he was injured, it was only two weeks before his 19 birthday.

Hemingway's ultimate concern is art, not trauma. However, Yang's personality theory can unify Hemingway's personality and his works in a local scope. Moreover, for Hemingway to observe the war and for this artist, this theory has given special significance. A Farewell to Arms and some short stories describe the social, emotional and moral significance of war. However, it is not only this description that makes his war experience "valuable": it forged his view on human destiny in his mind, which influenced almost all his works. Mortar fragments have become a symbol of the destructive power of the cruel world, and Hemingway and his hero have become symbols of the injured human beings seeking a way to survive. He is almost ready to turn that perception of life into a literary work.

1942 to 1944, he was sent by Corriere magazine to the third army of General Patton as a journalist without military status. During this period, Hemingway patrolled the sea with the pilar. The pilar was funded by the government, equipped with communication and blasting facilities, and became an anti-submarine warship in disguise. Although "pilar" didn't encounter submarines (if it did, Hemingway would have ordered himself to throw grenades and incendiary bombs at the control tower), Hemingway's report may have helped the navy detect the positions of some submarines and sank them, and Hemingway was commended for these achievements. 1944 Hemingway cooperated with the Royal Air Force and took part in several battles by plane. He was not injured, but in a car accident during the blackout in London, his head and knees were injured. Several newspapers published his obituary, but not long after, Hemingway watched the battle for a few minutes at Fox Green Beach in Normandy before returning to the ship on the day of allied landing. An imitation show in memory of this great writer.

Although he nominally belonged to General Patton's army, he acted together with the Fourth Infantry Division of the First Army and participated in the Battle of the Liberation of Paris and the Battle of the Convex Land. His bold description is exaggerated or distorted, but he acts more like a soldier than a reporter. He patrolled a post on the outskirts of Paris and asked for information, collecting information for the advance of General Leclerc's troops, which was very effective. During the German counterattack, he risked his life to enter the Hertmann forest and took part in fierce fighting with short weapons. Soldiers have a better impression of him than journalists. Perhaps his colleagues were angry because of his arrogant attitude, or perhaps he exaggerated how he personally led a small guerrilla liberation travel club and Ritz Hotel. A group of reporters accused Hemingway of violating the Geneva Convention that war correspondents are not allowed to take part in combat. Hemingway appeared in court, escaped conviction after a short trial, and later won a bronze star medal. Hemingway was forty-six years old when the war ended. The image he described for himself as a war-torn and indomitable veteran is no longer a pencil sketch, but a full-length portrait painted with gloomy pigments. What else is there? Hemingway explained through his words and deeds that he wanted to have a new start in life and art. During the war years, he only published a report on the Sino-Japanese war written for Afternoon and a telegram written for Corriere and brought back from the European war zone. Now he generally claims to be writing a work, a novel about "land, sea and sky". Hemingway divorced martha gellhorn at the end of 1945, as if to strengthen his sense of rebirth, and returned to the "lookout farm" in March of 1946, accompanied by his fourth and last wife, Mary Welsh, who was a journalist.
