Fuller doesn't blush from the atrocities committed by all sides in that long series of conflicts.
I think Sam's delight must have been at Fuller's turn of phrase and wit, more than content.
In this reference to a plot by two monks in 1213 to entice probably homeless youth of Germany and France to join a crusade (to be instead delivered into slavery), Fuller guesses at a cause: "the devil, being cloyed with the murdering of men, desired a cordial of children's blood to comfort his weak stomach." Elegant trochees and iambs waltzing through horror. Sam must have chortled.
