This is a story before Nogi's heroic story was created. Reported in 1905 from the battlefield.
During the battle for a hill of Port Arthur, raising a red cross flag, Japanese side had to offer Russian side a cease-fire to remove remains from the slope because there were too many to continue the battle. Japanese and Russian officers negotiated schedule for it exchanging cigarettes and drinking whiskey together on the slope.
J: I'm afraid you are tired sirs as this war is not over yet.
R1: Thanks for your care sir but we are still fine though I hope this war will be over as soon as possible.
J: I agree. I want peace as war is tragic. Such a battle against the fortress like this is especially tragic.
R1: I want peace too. I want to stop this war but no way as my country doesn't.
R2: War is cruel. I want to stop it but I have to fight because Japan doesn't stop.
R3: We may give you Port Arthur anytime but your bloodshed is not enough yet.
R4: I envy your mail service in the battlefield. May I hand you my mail for my family?
They enjoyed free talk like this on the slope for 3 hours.
