I'm currently reading the Swedish translation of Yock von Wartenberg's "Napoleon as Fledherr". In the introduction, there is a quote of a characterization of Napoleon which is said to be from his graduation from École Militaire in 1786 (should be 1785?). I have no reason to doubt its truth, but given the amount of misinformation and alternative facts that circulate about Napoleon, I would like to trace this quote to a more certain source (Y von W does not give one).

This is a quick translation. Given that this is my translation into English from Gustaf Moberg's 1889 translation into Swedish from Yock von Wartenberg's 1884 into Geman from some French source, a lot might have been lost in translation. Still, the text is pretty harsh on Napoleon and I hope that someone may recognize it.

"Offish and industrious, he puts all kinds of study before fun, finds pleasure in reading good authors, is pretty diligent in the abstract sciences, but not much interested in the others, well versed in mathematics and geography; taciturn, loves loneliness, willful, proud and much given to egotism, speaks but little but with energy, witty and sharp in his answers, very conceited, ambitious and aspiring; this young man should be given prominence".
