Answer:
This is a subject which has caused a lot of controversy over the years .
He ignored the advice to change the tactics, he sent millions of shells over to the German trenches thinking it would kill all the soldiers but the German spy planes saw what he was doing and the German soldiers dug really deep trenches and Haig sent the british soldiers over with just walking sticks not riffels and over 900 british soldiers were killed in half an hour but no German soldiers were killed. The oly good point about Douglas Haig is that he won the war and wore the German soldiers down.
However in haig's defence his idea to tire the German front line was successful as in a German army record it said - 'we were exhausted etc.'
Haig was only trying to do his best for his King and his country. To win the war
