Why was Douglas haig called a hero?

Douglas Haig, the British commander during World War I, was often called a hero for his leadership in key battles, particularly the Battle of the Somme and the Battle of Passchendaele. His strategies, although controversial and costly in terms of human life, were seen by some as necessary to wear down German forces and contribute to the eventual Allied victory. Supporters argue that he demonstrated resilience and determination in a challenging war environment. However, his legacy remains contentious due to the high casualties associated with his tactics.
