En Hai later gave himself up to the Allied occupying forces. He was subsequently tried and convicted, and was executed in Beijing on 31 December 1900 by beheading. He showed no emotion during interrogation, and was fully composed and calm, admitting to killing Ketteler, and even requested execution, saying "I received orders from my sergeant to kill every foreigner that came up the street...I am glad to die for having killed one of the enemies of my country." When questioned about whether he had consumed alcohol during the incident, En Hai said he had not "touched a drop". En Hai was praised as "brave and dignified", and called a "hero".
