In page Ian Hamilton (British Army officer):

"

This military confrontation between a well-known European army and a less-familiar Asian army was the first time that the tactics of entrenched positions for infantry were defended with machine guns and artillery. This was the first twentieth-century war in which the technology of warfare became increasingly important, factors which came to dominate the evolution of warfare during the First World War. Hamilton wrote that cavalry was obsolete in such a conflict, regarding their role as better accomplished by mounted infantry. He became a supporter of non-traditional tactics such as night attacks and the use of aircraft. Conversely the successful Japanese infantry assaults convinced him that superior morale would allow an attacker to overcome prepared defensive positions.
