"We once discussed which were the cleanest troops in the trenches, taken by nationalities. We agreed on a descending-order like this: English and German Protestants; Northern Irish, Welsh and Canadians; Irish and German Catholics; Scots; Mohammedan Indians; Algerians; Portugese; Belgians; French. We put the Belgians and French there for spite; they could not have been dirtier than the Algerians and the Portugese."
