Sun Jian
After Dong Zhuo retreated to Chang'an, Sun Jian was the first to enter Luoyang and ordered to put off the fires set by Dong Zhuo. Seeing the destruction of the imperial capital and Han dynasty, Sun Jian sighed and shed a tear. However, when his men found a jade seal, which was proven to be the imperial seal, Sun Jian grew ambitious and requested to retreat to his base. The news was leaked, to Sun Jian's miscalculation. When Yuan Shao, the leader of the coalition, interrogated Sun Jian, the latter swore by saying, "Should I have hid the treasure, I shall die miserably under arrows!" Under the protection by his guards, Sun Jian left Luoyang immediately.
