The Crusades were essentially cavalry wars and sieges, eventually won by the Muslims, and the incredible military success of the Mongols in the 13th cent. was based on their cavalry. At the end of the Middle Ages, infantry came to the fore again but cavalry remained prominent in the armies of Louis XIV, Frederick II (Frederick the Great), and particularly Napoleon.
Introduction to night sweats. Doctors in primary care fields of medicine often hear their patients complain of night sweats as they are common. Night sweats refer to any excess sweating occurring during the night. However, if your bedroom is unusually hot or you are using too many bedclothes, you may begin to sweat during sleep, which is normal.
Consider your environment. If the room that you are sleeping in is too warm, it can cause night sweats. Having too many blankets is another cause of night sweats. These causes are the easiest to fix. It is just a matter of adjusting the temperature, or removing some of the covers.
