In Berlin they had asked a soldier from Lobberich for an escape route across the border and had been referred to a Lobbericher known as a smuggler who would show them the way. The smuggler reported them to the local police and during the interrogation in the imperial barracks on Poststrasse in Kaldenkirchen, the two shot themselves in separate rooms. Count Uxkull was instantly dead; Lieutenant Cohrs died in the hospital a day later. They were buried in the Protestant cemetery in Kaldenkirchen, where a memorial stone is still commemorating them.
