"With regard to that portion of the petition which asks that special precautions may be taken to prevent danger to the lives of the "Golocanda" passengers by submarine attack, I feel bound to express my astonishment that the Austro-Hungarian Government, themselves one of the authors of the danger, should have thought it seemly to endorse this request. Not content, however, with doing this, the Austro-Hungarian Government further state that they will hold His Majesty's Government responsible for the lives and well-being of those passengers, "the majority of whom are better-class people." I am at a loss to know why "better-class people" should be thought more entitled to protection from submarine attack than any other non-combatants, but, however that may be, the only danger of the character indicated which threatens any of the passengers on the Golonda is one for which the Austro-Hungarian and German Governments are alone responsible. It is they and they only who have instituted and carry on a novel and inhuman form of warfare, which disregards all the hitherto accepted principles of international law, and necessarily endangers the lives of non-combatants."
