I just finished watching "World War II on the Map" before watching this movie (if you are interested in World War II, I recommend it to everyone to watch it), so I have a fresh concept of the Atlantic naval battle, and I feel a sense of a background and basic knowledge. The film presents the fourth stage of the Atlantic naval battle. The success rate of German U-boats in destroying merchant ships has dropped significantly this year, and they have been repeatedly failed to be destroyed. The wolf pack tactic does not seem to be as effective as before because of the escort of American frigates. On the other hand, the reinforcement and combat readiness of U-type submarines is very insufficient. Germany can only produce 2 search U-type submarines a month, which can not fill the vacancy of sinking. The Battle of the Atlantic Ocean reflected the tragic nature of World War II from the side. The entire film is intense and exciting. The navy has rich professional knowledge, solid practical operation ability, rapid response ability, and calmness in the face of crises. Hanks is excellent. ???? The film does not depict the situation of the soldiers on the German U-type submarine, but after reading the information, there are often 50 U-type submarine soldiers in a search. The submarine is crowded with turbid air. There is only one toilet for so many people. It can take up to three months, so risking your life in such a claustrophobic space should be difficult.
After all, the war is over, and the party who waged war without justice, democracy and freedom has violated the law of natural existence. More still, what is the purpose of war? What did the war cost us? I think that's what the movie is about.
