During the Siege of Port Arthur in the Russo-Japanese War, Japanese soldiers evacuated the enormous number of Japanese military casualties. In the first through third assaults on Port Arthur, the Japanese military suffered approximately 15,400 killed in action and about 44,000 wounded.

 　During the attack on Port Arthur in the Russo-Japanese War, Japanese soldiers repatriated the enormous number of Japanese military casualties. In the first general assault on Port Arthur alone, from August 19 to August 24, 1904, the Japanese forces suffered casualties of 15,800 out of the 50,700 soldiers who participated. The Russian forces also suffered significant losses of approximately 3,000 men. During the first half of the second general assault (September 19-22) and the third general assault (November 26-December 6), the Japanese captured Hill 203. From the first to the third assault on Port Arthur, the Japanese Army suffered approximately 15,400 killed and 44,000 wounded. Russian casualties amounted to approximately 16,000 killed and 30,000 wounded. 

　On August 19, 1904, General Nogi Maresuke, commander of the Third Army, issued orders to all Japanese divisions to launch a general assault on the Port Arthur fortress. The objective of capturing Port Arthur was to seize the fortress before the Russian Baltic Fleet could sail east, destroy the Russian fleet within Port Arthur Harbor, and thereby lift the blockade of Port Arthur by the Japanese fleet, conserving its strength. This attack on Port Arthur was carried out at the request of the Japanese Navy. With the Japanese Navy's urgent need, there was no time for a conventional assault; instead, a surprise attack was chosen.

　　On August 19th, under the order for the general assault on Port Arthur, all Japanese divisions launched their invasion simultaneously. However, the Russian defenses proved formidable, resisting the advance. Japanese troops charged in as human shields, piling corpses uselessly upon the hillsides. The Japanese divisions finally captured the East and West Bastions of Mount Banryong. Yet the Russians counterattacked relentlessly. They stabbed with swords, struck with rifles, and when firing ceased, hurled stones at each other, engaging in repeated hand-to-hand combat. After retreating, the Russians rained bullets down on the Japanese like hail from nearby gun emplacements. The Japanese paid a heavy price to secure these positions.

　The observation tower captured by the Japanese division's suicide squad through successive assaults on August 24 was immediately retaken by the enemy Russian forces, and the Japanese soldiers were almost entirely annihilated. The interior of the fort was filled with the corpses of Japanese soldiers. The slopes were also covered with bodies, leaving no gap in the ground. Finally, Commander Nogi Kiyotane abandoned the first general assault on Port Arthur and ordered the assault halted at 4:00 PM. The first general assault on Port Arthur, from August 19th to August 24th, became a true grave for both armies.
