Heidi

Gretl was the name of a lover of Klausi.

In September 1916, while Klausi and Gustav were at the German command bunker at Verdun, Gustav begged his fellow commander for an introduction to Gretl, but Klausi intended to keep the woman's affections to himself. The two Germans were unaware that their banter was being overheard by Indiana Jones.
