Henke and his unit finally abandoned Pillau on 25 April for the nearby Batterie Lehmberg fortifications at Neutief (Noytif was Russian correspondence of Neutef before 1946) [1][2] on the Frische Nehrung. After a failed breakout attempt around 200 men continued to resist the besieging Soviet forces to the last round at 15:30 on 27 April; Henke, refusing to surrender, then shot himself.
