Normally in the case of a siege there is an attacking party besieging the defending party, but in a trench war both parties are besiegers and besieged at the same time.
The best known trench war is the First World War (1914-1918), but wars such as the Civil War (1861-1865) and the Russian-Japanese War (1904-05) also exhibited characteristics of trench wars.
