Did we tell cahn about Seydlitz' syphilis yet? If we didn't, Cahn, Seydlitz really would have benefited from a break. He had contracted syphilis at a young age, and eventually died in the tertiary stage. There was a period of enstrangement from Fritz but also a reconciliation, and a very sad final meeting,. To quote Wiki: In August 1773, in his last illness, Frederick and Seydlitz met again at Seydlitz's home at Minkovsky near Ohlau (now Oława, Poland). The King sat beside his sickbed, horrified at Seydlitz's condition, and even persuaded him to take some of his medications, but Seydlitz would not look at him; the illness had already deformed his face.
