There were changes now in the enemy tactics. In Maine they had been careful not to demolish the cities unduly. Their own people were settling there. But now, farther south, only the active warring giants advanced. They laid everything waste beneath their monstrous tread. An area a hundred miles wide had been wholly abandoned days before. The advancing giants waded into it; stamping, kicking--firing it by night with great torches. A blackened, wrecked swath of country stretched down from Maine. The giants were larger now. As their territory expanded they took a larger size. It was systematically done. Each seemed to have his post--a few miles over which he paced back and forth--with one of his fellows coming south at intervals to relieve him. And the reliefs were always larger--with more miles of country to pace. By June 1 it was estimated that they stood some five hundred feet tall. On June 1 they had reached Long Island Sound barely a hundred miles from New York City, where millions of people, in all the chaos, were still unable to get away. Giants had already crossed the Hudson. One of them stood in the river and lunged against Bear Mountain Bridge until he tore it loose. For all that the United States and Canada did not dare attack, there were frantic preparations for war. The battle planes were made ready. The Canadians were massed on the border--and a great fleet of American planes assembled in New Jersey. Artillery units were mobilized. Infantry would be useless. It was used now to aid the flight of the civilian population. The evacuated areas in advance of the giants were always under martial law, patrolled by soldiers who retreated slowly before the oncoming enemy. The forts of the Highlands near the Hook--entrance to the port of New York--were ready to do what they could; and the forts at Wadsworth, on Staten Island, were ready. The Atlantic battle-fleet was massed in the Chesapeake. The Pacific fleet was hastening through the Panama Canal. Resistance seemed so useless! By virtue of size alone, this enemy was irresistible. Monstrous, terrible weapon of size! No one, contemplating it, could even have approximated the terror of the reality. Yet it seemed horrible to do nothing. Father describes innumerable conferences in Washington, where the harassed government strove to plan what might be done. Nor was our government alone. The world was at stake. Every foreign government was frightened, offering help and advice. Help was coming. Transport planes, bringing volunteers from Britain, were daily arriving. They flew the far-south route--landed in the Carolinas, and were rushed North. A united, civilized earth opposed this enemy of giants. But to realize the desperate futility of it, one had only to envisage it from the giant viewpoint. A little, miniature world, like an anthill, outraged. Why, a single giant--Togaro alone--if he made himself large enough, could destroy this anthill activity!
