"Today we are fighting in a country which was contributed a great deal to our cultural inheritance, a country rich in monuments which...illustrate the growth of the civilization which is ours. We are bound to respect those monuments so far as war allows. If we have to choose between destroying a famous building and sacrificing our own men, then our men's lives count infinitely more and the building must go. But the choice is not always so clear-cut as that. Nothing can stand against the argument of military necessity. That is an accepted principle. But the phrase 'military necessity' is sometimes used where it would be more truthful to speak of military convenience or even personal convenience. I do not want it to cloak slackness or indifference. It is a responsibility of high commanders to determine through AMC Officers the locations of historical monuments whether they be immediately ahead of our front lines or in areas occupied by us. This information passed to lower echleons through normal channels places the responsibility on all commanders of complying with the spirit of this letter."
