The Ten Duel Commandments

Number one: The challenge, demand satisfaction. If they apologize, no need for further action.

Number two:
If they don't, grab a friend, that's your second. Your Lieutenant, when there's reckoning to be reckoned.

Number three:
Have your seconds meet face to face, Negotiate a peace or negotiate a time and place. This is commonplace, specially 'tween recruits.Most disputes die and no one shoots.

Number four:
If they don't reach a peace, that's alright
Time to get some pistols and a doctor on site. You pay him in advance, you treat him with civility. You have him turn around, so he can have deniability
Five:
Duel before the sun is in the sky,
Pick a place to die where it's high and dry.

Number six:
Leave a note for your next of kin. Tell 'em where you been, pray that Hell or Heaven lets you in.

Seven:
Confess your sins ready for the moment of adrenaline when you finally face your opponent.

Number eight:
Your last chance to negotiate
Send in your seconds see if they can set the record straight.

Number nine:
Look him in the eye, aim no higher.
Summon all the courage you require.
Then count, One, two, three, four, five, six, seven, eight, nine number (Ten paces!) Fire!
