Polish Lieuts. Niki Surmanowicz and Mietek Schmiel, doing time
in solitary confinement, somehow managed to get out of their locked cells and
into the prison yard. Friends in the Polish quarters in floors above lowered a
rope, which the pair used to get into the adjacent guardroom's attic. Putting
the same rope out the attic window on the castle's western side, they began
sliding down, but the nails in Schmiel's boots scraped on the wall, giving them
away.
