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.
Hot flashes and night sweats may be side effects of cancer or its treatment. Sweating is the body's way of lowering body temperature by causing heat loss through the skin. In patients with cancer, sweating may be caused by fever, a tumor, or cancer treatment. Hot flashes can also cause too much sweating. They may occur in natural menopause or in patients who have been treated for breast cancer or prostate cancer. Hot flashes combined with sweats that happen while sleeping are often called night sweats or hot flushes.
