The correct answer to this open question is the following.
Unfortunately, you did not attach the excerpt, explain Owen's point-of-view on the war on the Western Front during World War I. Without the text, we do not specifically know what you are talking about.
However, trying to help you, we can answer in the following general terms.
Here we are going to make reference to the point of view of Wilfred Owen (1893-1918), a British poet that participated in World War I, and unfortunately died during the war.
He was a poet and a soldier that defend the British during the war. He wrote poems that described the horrors of the war, particularly referring to the atrocities of the war in the trenches and the pain and suffering produced by the use of toxic gas as a weapon.
The adaptations that the soldiers made for fighting in the trenches during World War 1, allowed the troops to modify the strategy when they built the trenches in the war front. The trenches were built to protect soldiers from firearms from the enemy. The strategy used prolonged the war in what historians call "a stalemate in the Western Front," from 1914 to 1918. During this period, there were no significant advances on both sides.
The Allies, under the command of French leader Robert Nivelle, decide to move and attack the Germans, but they decide to withdraw to the Hinderburg Line. So plans changed, and the decision was to attack the Germans in the Battle of Arras of April 4, 1917, with the direct support of the British troops.
