1. The Battle of the Somme
The Battle of the Somme took place in the summer of 1916 and became a brutal event in World War I, with over one million soldiers killed or wounded in 141 days.
On the first day alone, 20,000 British troops lost their lives. What was planned as a quick attack turned into a long and tragic fight. The muddy trenches, failed strategies, and heavy losses made it a painful example of how cruel and costly war can be.
