The first German air raids were by Zeppelins on little English seaside towns--Scarborough, Hartlepool, and Harwich. Except in so far as they inflicted mutilation and death upon many non-combatants, mostly women and children, and misery upon their relatives and friends they were without effect. But early in 1915 began a systematic series of raids upon London, which, by October of 1917, had totalled thirty-four, with a toll of 865 persons killed, and 2500 wounded. It seems fair to say that for these raids there was more plausible excuse than for those on the peaceful little seaside bathing resorts and fishing villages. London is full of military and naval centres, arsenals and navy yards, executive offices and centres of warlike activity. An incendiary bomb dropped into the Bank of England, or the Admiralty, might paralyze the finances of the Empire, or throw the naval organization into a state of anarchy. But as a matter of fact the German bombs did nothing of the sort. They fell in the congested districts of London, "the crowded warrens of the poor." They spread wounds and death among peaceable theatre audiences. One dropped on a 'bus loaded with passengers homeward bound, and obliterated it and them from the face of the earth. But no building of the least military importance sustained any injury. It is true, however, that the persistent raiding has compelled England to withhold from the fighting lines in France several thousand men and several hundred guns in order to be in readiness to meet air raids in which Germany has never employed more than fifty machines and at most two hundred men, including both aviators and mechanics.
It is entirely probable that the failure of the Germans to strike targets of military importance and the slaughter they wrought among peaceful civilians were due to no intent or purpose on their part. Hitting a chosen target from the air is no matter of certainty. The bomb intended for the railway station is quite as likely to hit the adjacent public school or hospital. If the world ever recurs to that moderate degree of sanity and civilization which shall permit wars, but strive to regulate them in the interest of humanity this untrustworthiness of the aircraft's aim will compel some form of international regulation, just as the vulnerability of the submarine will force the amendment of the doctrine of visitation and search. But neither problem can be logically and reasonably solved in the middle of a war. And so, while the German violation of existing international law had the uncomfortable result for Germany of bringing the United States into the war, the barbarous raids upon London caused the British at last to turn aside from their commendable abstention from air raids on unfortified and non-military towns and prepare for reprisals in kind.
From the beginning of the war the British had abstained from bombing peaceful and non-military towns. They had not indeed been weak in the employment of their air forces. General Smuts speaking in October, 1917, said that the British had, in the month previous, dropped 207 tons of bombs behind the lines of the enemy. But the targets were airdromes, military camps, arsenals and munitions camps--not hospitals or kindergartens. The time had now come when this purely military campaign no longer satisfied an enraged British people who demanded the enforcement of the Mosaic law of an eye for an eye and a tooth for a tooth, against a people whom General Smuts described as "an enemy who apparently recognizes no laws, human or divine; who knows no pity or restraint, who sung Te Deums over the sinking of the Lusitania, and to whom the maiming and slaughter of women and children appear legitimate means of warfare."
And Premier Lloyd George, speaking to an audience of poor people in one of the congested districts which had suffered sorely from the a๋rial activities of the Hun, said:
"We will give it all back to them, and we will give it soon. We shall bomb Germany with compound interest."
