The "Samguk Sagi" relates to an event that purported to have happened in South Okjeo: Yuyu (紐由), another man of the Eastern District, feigned the surrender of King Dongcheon to stop the Wei pursuit. Bearing food and gifts, Yuyu was allowed into the camp of an unnamed Wei general. When the general received him, Yuyu pulled out a hidden dagger from under the plates and fatally stabbed the Wei general. He was likewise killed by the attendants at the next moment, but the damage had been done — the Wei army, having lost their commander, was thrown into confusion. King Dongcheon took this opportunity to gather his forces and struck his enemy in three columns. The Wei armies, unable to recover from the confusion, "at last retired from Lelang". This passage was not paralleled in Chinese records.
