At the beginning of the contest, a series of bulbous-headed arrows were shot, which buzzed in the air. The purpose of these shots was to call the "kami" to witness the displays of courage that were about to unfold. After a brief exchange of arrows between the two sides, a contest called "ikkiuchi" (一 騎 討 ち) was developed, where great rivals on both sides faced each other. After these individual combats, the major combats were given way, usually sending infantry troops led by samurai on horseback. At the beginning of the samurai battles, it was an honor to be the first to enter battle. This changed in the Sengoku period with the introduction of the arquebus. At the beginning of the use of firearms, the combat methodology was as follows: at the beginning an exchange of arquebus shots was made at a distance of approximately 100 meters; when the time was right, the "ashigaru" spearmen were ordered to advance and finally the samurai would attack, either on foot or on horseback. The army chief would sit in a scissor chair inside a semi-open tent called "maku", which exhibited its respective "mon" and represented the "bakufu", "government from the "maku"."
