sir John Smithe or Smith, XVI century English gentleman and soldier, wrote and had his military treatise published in 1594AD and reprinted in 1595 AD.
The entire book - 'Instructions, obseruations, and orders mylitarie : Requisite for all chieftaines, captaines, and higher and lower men of charge, and officers to understand, knowe, and observe' - is available on google books for reading or download.
Inside there are some very interesting observations from a soldier who served on the Catholic sides seeing plenty of action in Kingdom of France, Holy Roman Empire and in Hungaries (Hungarian Kingdom divided between the Ottoman and Imperial powers) for about 20 years, finally returning to England circa 1572AD.
He wrote about lance bearing cavalry of the times: stradiots, men-at-arms, boder horse (particular to English-Scottish borderlands)light cavalry, and demi-lancers. He covered the equipment (like the estoc to be carried under rider's thigh in the manner of Turks or Hungarians), training, and tactics and many other things in his work.
I have just started reading and studying this treatise, looking forward to see much interesting information.
