Hi
Despite I havent read Sweetman book, it is obvious to me that he have gotten the "whole" situation completely wrong...
Many of the German flyers who successfully participated in this battle was DIRECTLY mentioned in official(also some with names) sources...so whats the problem..?
Many of them also got decorations, promotions etc
One of the book in the series "Schlachten des Weltkriges" is about the battle of Tannenberg and probably gives another version than Sweetman...
As mentioned before, the official German history of their Air Force during WW1 were able to publish the first two volumes which contains the aerial operation during the Tannenberg, before allied bombing during WW2 prevented further publication...
I think they are called Sonderband 7 and 8..?
Most of the Taube a/c were unsuitable for aerial war when the War started because they were slow and hardly could reach 1000 meter...so they were rather easy targets also for ground mg..
However as most of them were quickly withdrawn from the Western front, I think they stayed a bit longer on eastern front were the concentration of troops was more outspread.
But the Taubes were probably useable for reconnaissance work
I dont knew what a/c the Russian and French used on the eastern front, but they likely had far more better a/c than the Germans...
As an answer Barretts question, far more early German flyers survived the War than generally expected, even those who continue to be active..
just some thoughts
