Friedrich August 1900-1918

Chief of IR91 and 17 and Dragoon Regiment 19. Once again I have 2 chief's of IR17! Perhaps the source should have said IR70.

2nd & 3rd Bn. Fld Arty Regiment #62

Dragoon Regiment 19.

The grand duke was the colonel of IR70 but there was no Oldenburg plate for that unit. 

His wife was a Princess of Mecklenburg-Schwerin.
