One of those who took part in the education course, Adolf Gemlich, had addressed several questions to Captain Mayr, who passed the letter on to Hitler for reply. Hitler's letter to Gemlich is dated 16th September 1919, and is reproduced together with other letters in the papers of Ernst Deuerlein already referred to (Documents 10 et seq.). It is perhaps worth noting that Hitler's pronounced oratorical style (Redestil) is already apparent in this letter, particularly in the last sentence.
