i can only agree with Rammjaeger that these are not questions with simple answers. i have spent almost 40 years researching the aviation on the Russian and Romanian fronts. sadly massive holes in the German information. like Rammjaeger i also have time constraints preparing two books on these subjects and creating a website dedicated to Russia in World War I. plus health and other issues that continually delay projects. as for geographical locations i would suggest visiting
www.warchron.com and checking the newly updated Map section which is now available. there will be more to come with regard to maps of these eastern areas. modern day maps are totally useless as so many name changes have taken place. simple questions are not simple at all. they involve far deeper examination to prepare answers, if any are to be found and shared. best of luck with your future researches. please visit warchron for future answers. best wishes, august
