When they saw Xiang Yu coming, they laid down their weapons and took refuge in Xiang Yu. Xiang Yu shouted a slogan to the allied forces, and the surrenders can let bygones be bygones, which is the fundamental reason why Liu Bang's allied forces have no resistance. More than 500 thousand people fled together, and Xiang Yu's cavalry beat them to pieces, which was simply cutting melons and vegetables.
Although Xiang Yu has only 30,000 soldiers and horses, his strategy is appropriate. Liu bang's army launched a surprise attack behind Liu bang's defense line, caught off guard and naturally collapsed thousands of miles away. The third is Xiang Yu's pursuit of victory. After Liu Bang's defeat in the Battle of Pengcheng, Xiang Yu chose to pursue Liu Bang in one go, which led to Liu Bang's failure to reorganize the army to fight against Xiang Yu. Liu Bang's 560,000 people were naturally wiped out by Xiang Yu's 30,000 people.
After Xiang Yu got the news that the capital was occupied, dispatch troops didn't all fight back against Liu Bang. He still let the big troops continue to attack Qi to confuse his opponents. In fact, they secretly organized elite troops to travel around the clock, marching thousands of miles in just two or three days and quietly returning to Chu.
After prior investigation, Xiang Yu led an army to attack Xiao County, where Liu Bang's defense was the weakest. The time was chosen at dawn, when the army had already fallen asleep. Faced with a sudden attack, many allied soldiers were cut to the ground before they could take up their weapons and then fled for their lives. In this battle, Xiang Yu first put smoke bombs to confuse his opponents, and then made a surprise victory. Liu bang is hard to be unbeaten.
