How far was haig a successful military leader?

General Douglas Haig's success as a military leader during World War I is a topic of considerable debate. While he is credited with strategic victories, such as the Battle of the Somme and the Battle of Passchendaele, his tactics often resulted in heavy casualties and criticism for the high human cost. Some argue that his commitment to attrition warfare ultimately contributed to the defeat of Germany, while others contend that his leadership was marked by a lack of adaptability and a failure to learn from earlier mistakes. Thus, his legacy remains complex, reflecting both achievements and significant losses.
