Krztalizer difference in the night war against the teiffliegers.

You mean 'Tiefflieger'?

Yep - I manage to mangle the spelling every time, and its in many of the
documents I have to translate.

I.e. low level strafers.... at night?

Usually used that way, but also used to describe British Main Force raiders.

Could you elaborate? Obviously I missed some reading here, but are
you referring to Mosquito raids or what, maybe intruders?

I think prox fuses could well have done the job to counter the Mosquito - if it
worked against V-1s, I can't see them having a problem with Mossies sent to
Berlin on routes so routinely used that they were known to air defense forces
as railway "tracks". By the same token, Sterlings lumbering along in the dark
at 14,000' wouldn't be much of a challenge to an AA battery with proximity
fuses. Considering the prewar Oslo letter contained an advanced proximity
fuse, it appears the wartime German leadership never made it the priority it
should have been.
