After you go into the pub and tip the piano player, he will play a song and distract the guards to the stairs leading up to the balcony. There will be two men at the top, and down the stairs at the bottom will be two more men. To the right of the men on the top, there will be three beer mugs. Go over to them and press Action. You will tip the mugs one by one off the balcony onto the table of the men on the bottom. They will argue each time you tip one. After the third beer mug is tipped, the man on the top will jump down and they will start punching each other. It will slow, but after about ten to twenty seconds, one of the men will tackle the other one and punch him in the face while he is on the ground. After the man is pinned down and beat up, you may as well end the mission because this will continue until you do so. Note: To see what the Nazis are saying when they are arguing, turn on the subtitles.
