“…a reminder of that blood-stained field of Karbala, where the grandson of the Apostle of God fell, at length, tortured by thirst, and surround by the bodies of his murdered kinsmen, has been at anytime since then, sufficient to evoke, even in the most lukewarm and the heedless, the deepest emotion, the most frantic grief, and an exaltation of spirit before which pain, danger, and death shrink to unconsidered trifles.”
