Fromelles: an Australian tragedy (Aaron Pegram, The Strategist)

The Australian Imperial Force (AIF) proved fortunate in being spared the first day of fighting on 1 July, 1916 as the British Army attacked the Somme in northern France. That first day of the Somme offensive cost the British more than 57,000 casualties, including 19,240 dead.
