On 27 May, the British fought back to the Dunkirk perimeter line. The Le Paradis massacre took place that day, when the 3rd SS Division "Totenkopf" machine-gunned 97 British and French prisoners near the La Bassée Canal. The British prisoners were from the 2nd Battalion, Royal Norfolk Regiment, part of the 4th Brigade of the 2nd Division. The SS men lined them up against the wall of a barn and shot them all; only two survived. Meanwhile, the Luftwaffe dropped bombs and leaflets on the Allied armies. The leaflets showed a map of the situation. They read, in English and French: "British soldiers! Look at the map: it gives your true situation! Your troops are entirely surrounded—stop fighting! Put down your arms!" To the land- and air-minded Germans, the sea seemed an impassable barrier, so they believed the Allies were surrounded; but the British saw the sea as a route to safety.
