that my precious baby Model was a member of literary society during his youth excelled in Greek, Latin, and History (and some also say in Poetry — I wonder if he ever wrote a poem).

Von Leeb loved to collect stamps!!! and very fond of his family's chronicles.

There is a story in the Keitel Family that Wilhelm almost went to tears when he gave up his hope to become a farmer in order to stay in the military to support his family.

Von Reichenau was fond of German literature and classical music. He brought to the battlefield in the Polish campaign a small volume of a selection of German poetry.

Von Rundstedt loved detective thriller books but was shy to show it. He regularly read the novel in an open drawer which could be quickly closed whenever anyone came in to see him.

Rommel and Schörner's rivalry. David Irving wrote: "One of Schoerner’s frequent pranks was to plant silver cutlery from the mess in the pockets of guests at formal banquets and watch their embarrassment when the spoons and forks fell out. Rommel, when it happened to him, was not amused. Their rivalry persisted to the end. It was generally friendly, and once, after Schoerner had made a name for ruthlessness bordering on brutality in the Crimea ... Rommel solicitously took him aside and candidly urged him to try a different method."

Von Bock seemed to be very fond of boys —not in the negative way. In Sudetenland, he once "took his twelve-year-old son, dressed in a sailor suit, along in his car "to impress on his son the beauty and exhilaration that lie in soldiering."". In 1940, he sent a postcard to the same son, Dinnies von der Osten. Also, one of Fedi's last wishes to von Manstein was that he should take care of the 16 year old Dinnies after his death, which Erli did until his capitulation. Not that it matters, but Dinnies was not his biological son. It was his second wife's son from her previous marriage. I think it shows how much Fedi cared for the boy. Then, his diary entry on 8/9/39: " ... I was able to present the first Iron Cross of this war to a Private First Class of the 94th Regiment who acted bravely at Graudenz. The young man beamed; too beautiful these lads!". He's just ... adores his troops (and youngest stepson) so much :')

Wolfram von Richthofen always found studying language to be painful. His foreign language grades were either a borderline pass or an “unsatisfactory.” And "he was a somewhat indulgent father. When he returned home during the war years, Jutta would relate some minor misbehavior of the boys and ask that Wolfram, as their father, discipline them. Wolfram’s reply was usually something on the lines of “boys will be boys” and “they’re good kids—let’s give them a break.”". Then, Wolfram once described the Luftwaffe as “the army’s whore”.

Von Manstein's writing is something else. Even if he did lie about the breakout order in Stalingrad, I still enjoyed his memoirs, to be honest. His words are beautiful, the way he tells a story and the allusions — I got the impression that he was a highly educated person by reading Lost Victories.

Also, von Küchler and Busch's rivalry (which was bitter, unlike the Rommel-Schörner's one), which unfortunately I couldn't remember which book explained that and couldn't find it yet :(
