Losses suffered by Roman troops in the Battle of Kannai.

 The Battle of Cannae was a perfect siege annihilation battle throughout the ancient Western war history. Perhaps there was no such war of extinction in the history of the Western War until World War I. Rome's losses in this battle were so enormous that this battle attracted great attention from Western military historians since modern times. How much damage was the Roman army? For now, it is impossible to know exactly about the damage of the Roman army. It can be seen as just finding out an estimate close to it. It is estimated that about 86,000 Roman troops were put into the battle in Canna. Among them, 80,000 infantry and 6,000 cavalry. It is estimated that there are 55,600 regular soldiers and 22,400 assistants. Rome put 70,000 infantry and 6,000 cavalry into the battle. It is said that 10,000 troops remain in the Roman military camp, and Hans Delbruck, a German military historian, estimated that 2,600 of them were regular corps soldiers and 7,400 were assistants. The Roman army placed 55,000 soldiers in the center, 4,000 assistants on both sides of the corps, and finally placed cavalry at the end. 7,000 assistants remained in reserve after the main camp. In order to increase the impact effect during the attack, the Roman army narrowed the front and placed the enemy's heart deeply despite more troops than Hannibal. As a result, the collapse of the cavalry resulted in the easy siege and annihilation of the Carthage army. Then, how much did the casualties occur? Polybios, a historian who left a record of the battle in Canna, said that the Roman army had 70,000 dead and 10,000 prisoners of war, and 3,000 infantry and 370 cavalry barely survived and fled. According to Livius' records, 45,000 infantry and 2,700 cavalry were killed, 18,000 infantry were captured, and 1,500 cavalry were captured. According to his records, 52,000 of the 55,000 infantry deployed in the battle were killed. There were only 3,000 prisoners. The rest of the prisoners were soldiers who remained in the camp and were captured or stationed in the village in Canna and surrendered. Western historians believe that Livius' record is more reliable than Polybios. Delbruck supported Libby's view in a book published in 1908. Delbruck supports Livius' view because there is a record that Rome has formed two fully organized regular corps with soldiers who have returned from the battle of Canna. For now, Rome put 80,000 infantry and 6,000 cavalry into the battle of Canna, and Delbruck argues that if there were 13,000 prisoners of war, only 3,000 survivors would not be able to form a single corps with this force. It is estimated that during the Punic War, one legion was organized into about 5,000 people. In other words, the two corps are about 10,000. The estimated casualties of the Roman army by Delbruck are as follows. Warrior infantry 45,500 cavalry 2,700 infantry: 18,000 cavalry: 1,500 Survivor infantry: 14,000 cavalry: 2,500 unknown: 2,500 (delbruck himself said he was not sure).
