Same week, elsewhere
1916 marked the collapse of Victorian optimism about progress and martial glory. The Somme's scale and futility—640,000+ British/French casualties for 6 miles of ground—shattered illusions of quick victory and crystallized a generation's disillusionment. Modernist art and literature (Pound, Eliot, Owen) increasingly rejected Edwardian certainty; the war became synonymous with meaningless mechanized death.

Impact
What followed.
The Somme demonstrated the lethal mismatch between 19th-century tactics and 20th-century weaponry. The battle's staggering casualty toll-60,000 British soldiers on the first day alone-reshaped how militaries understood industrial warfare, though lessons were learned slowly and at enormous cost.
