Who is Leutnant Wollers from The Forgotten Soldier and what is their importance?

Leutnant (Lieutenant) Wollers takes over command of the company in which Sajer serves following the death of Hauptmann Wesreidau. He appears to have been within the company prior to his taking command as all the men know him. His command is marked by constant combat, insufficient supplies, and contradictory orders. Wollers enjoys the confidence of the men, and he is an able leader. He prosecutes the war effort with dedication, but when he realizes all is lost he tried to preserve his men whenever possible. He makes no overt effort to regain the combat zone and instead prefers to let his men evacuate Memel during the last days of fighting. He surrenders to British forces in the west with the remainder of his men.
