In 1655, Martino Martini suggested that the word China is derived ultimately from the name of the Qin dynasty (221–206 BCE). Although use in Indian sources precedes this dynasty, this derivation is still given in various sources. The origin of the Sanskrit word
15621-605: Was largely replaced by mounted soldiers. It was not until later in the Middle Ages , that military engineering saw a revival focused on siege warfare. Military engineers planned castles and fortresses. When laying siege, they planned and oversaw efforts to penetrate castle defenses. When castles served a military purpose, one of the tasks of the sappers was to weaken the bases of walls to enable them to be breached before means of thwarting these activities were devised. Broadly speaking, sappers were experts at demolishing or otherwise overcoming or bypassing fortification systems. With
