Hi Regulus
Interesting that Wolff and Hintz victory was a night victory..!
Who will solve the so called "mystery" about Christiansen victories...
It seems that as more people search---the less is his real score of confirmed arerial victories.. 8)
The answer is certain to find in the archive in Freiburg...
I am rather convinced the "Wall" you mention above indeed is Lt zS Ludwig Wahl born 7 Aug 1895.
He was promoted officer on 17 Sep 1917.
In March 1917 he joined the I SFA for training.
In Sep 1917 he joined the SFS in Libau and was later transferred to SFS Reval.
In early June 1918 he joined SFS I(Zebrügge) as pilot where he is noted as serving until EOW....
Unfortunate I cant find the date he received the Seefliegerabzeichen... >
