Whoops Raggy you've just dropped another one - FFS man why don't you just check things before you shove your feet in your mouth.

1: Nameless Guest had your Kiggell chap as ending up in 1918 as GSO1 of a Division in the Army under Haig - Go away and find out how many Divisions made up Haig's Army in France - I know YOU might find it strange but not every Lt-Colonel or Colonel was a personal acquaintance of Field Marshal Haig.

2: If Nameless Guest's chap Kiggell was as you say Chief of the Defence Staff (Well hate to be really picky but the title did not exist in 1918 it would actually have been Chief of the Imperial General Staff) and Haig would have been HIS subordinate.

Oh and Nameless GUEST it would greatly depend upon what Kiggell's duties were on his Divisional Staff as to whether or not he needed to know "the conditions under which the soldiers lived and fought".
