Answer:
The speaker cannot recall the why of this "famous victory."
Step-by-step explanation:
"The Battle of Blenheim" is a poem written by Robert Southley. It starts with one summer evening when Peterkin saw a shiny thing beside a small stream. Kaspar, Peterkin's brother who was an old man, claimed it was a skull and that it belonged to someone who died in the battle, they call "the famous victory."
Many of the men who died turned out whenever Kaspar ploughs the field. This means many people actually died in that battle. No matter how victorious that battle was, it didn't occur to Peterkin that the battle was right. Thus, he asked why they call the battle victorious when, in fact, many innocent lives were lost. For him, battles should have a morally upright purpose and not just killing thousands of people because of power and greed. His grandchild also asked him the same question. This makes the whole phrase, "the great victory," ironic.
Thus, this explains the answer.
