李如松
Li Rusong sent ahead the envoy Shen Weijing to negotiate with Konishi Yukinaga, however this act was insincere. He had no intention of negotiating with the Japanese. Konishi sent 20 men to greet the Ming envoys, but most of them did not return. It's not certain what happened to them. One version of events state that they were killed during a banquet with Shen Weijing, another says they were simply ambushed on the way.
