Major Gordon Corrigan presents a profile of Field Marshal Douglas Haig, commander-in-chief of British forces during World War One's Battle of the Somme. Corrigan explains why he believes the military leader does not deserve to be blamed for the thousands of British casualties, and actually played a key role in winning the war thanks to his co-ordinated use of planes, tanks and troops. Douglas Haig was the man who took a tiny British army, expanded it five fold through the inclusion of the Commonwealth countries, then trained and deployed it to fight until it was the only allied army capable of defeating the Germans in 1918.
