Vortrag über die Einsatzbereitschaft - a source to changes and statistics

A strength return was fronted by a 'Vortrag über die Einsatzbereitschaft der fliegenden Verbänden'.

This introduction gave an overview of the changes, both regarding specific units and in total.

To revive the blog I will enter these as they give, in my opinion, a good insight in how the units themselves reported their strength - every week and later in the war every ten days.
