Explanation:
The Bayeux Tapestry depicts the attack performed by William II to England in the 11th century, and his subsequent victory over King Harold. In the tapestry, the artist draws the Normand armies, the tactics used in the battle, Harold's death and other aspects of war. The same happens with the Stele of Naram-Sin which depicts the victories of King Sargon of Akkad, and the Trajan Column represents the war against the Dacians performed by Emperor Trajan and his army, and his posterior victory.
