I&;m Sasha. I&;ll answer. The contradiction is actually very serious. Why does the Pacific War seem to have nothing wrong with the Japanese navy and army? This is because the navy&;s series of operations hardly require the cooperation of the army. For example, the attack on Pearl Harbor, the naval battle on Coral Island, the naval battle on Midway Island and so on. All the army needs is to land on a navy transport ship, then fight on its own and receive supplies from the navy. Of course, everyone noticed that the large-scale operations that the army participated in were mainly confined to Southeast Asia, and the difficulty was not great. At that time, the defense of the Allied forces in Southeast Asia was close to collapse. Other than that, let&;s take a look at the naval and army dismantling Taiwan during the occupation of Qingdao. Due to military strategic reasons, the Japanese army attacked Shandong from north to south, and Qingdao was located too far east, which had no defensive significance. Therefore, after the fall of Nanking on December 13th, Shen Honglie, the mayor of Qingdao, executed the general evacuation order. Several Japanese factories worth more than 200 million yen in Qingdao were all bombed from the night of 18th to the morning of 19th. At this time, Qingdao port has been blocked by sunken ships, the lighthouse has also been destroyed, and mines have been laid in the nearby waters. At that time, there was no main force near Qingdao, only about 2,000 marines and about 3,000 local security forces. By the end of December, these troops, together with the municipal authorities, had moved outside the city, leaving only a small number of police officers and special police teams mainly composed of Germans and other third-country expatriates to temporarily maintain order in the city. Obviously, at this time, the Japanese army did not occupy but received Qingdao. According to the agreement of the Japanese navy and army, Qingdao should be occupied by Qinghai. Specifically, on the night of January 7, 1938, the Japanese Navy Military Command issued a notice to Tanigawa Kiyoshi, the commander of the Japanese fleet in Shanghai, that while carrying out the task of blocking the coast, the camera captured Qingdao. To this end, Soeda Sobu, commander of the Japanese 4th Fleet, formed a naval force to attack Qingdao in late December, and began to assemble at the Qinziwo in Liaodong Peninsula and the Lichangshan Islands base in the south of Chengzituan on January 2. However, knowing that Qingdao should be occupied by the navy, the army stepped in. On January 8, the Japanese army actually ordered the &”;North China Army&”; to attack Qingdao in the name of. 9, Hisaichi Terauchi&;s &”;North China Army&”; is about to reach the second army of Xiwei Shouzao under this order. The 5th Division of the 2nd Army, which took the task of capturing Qingdao eastward along the Jiaoji Line, was still advancing at a high speed along the destroyed road, trying to seize Qingdao before the navy did. The 10th United Team of Yukichiro Nagano, the pioneer, arrived in Qingdao on January 13th at all costs. The navy found that the army tried to seize Qingdao and decisively sent troops in advance. At 18: 30 on January 10, Qingdao was occupied by the enemy&;s fourth fleet, and the army returned in vain. According to the information, Japan&;s army and navy have always had deep contradictions and are not convinced of each other. This time, the Fourth Fleet of the Navy did not cooperate with the Army to occupy Qingdao alone, and the Army Commander was very dissatisfied with this. However, the navy is afraid that the army&;s entry into the city will cause inconvenience to its security, port, railway, airport, barracks, communication and building use, so it is in many buildings,The facilities and receiving units are labeled with the words &”;Navy Management&”;. Shortly after the 5th Division entered the city, it had a dispute with the navy over the garrison and guard areas, and the two sides refused to give way to each other, resulting in a deadlock and almost exchanged fire by force.
