The second monster followed the first, and at that the artilleryman began to crawl very cautiously across the hot heather ash towards Horsell. He managed to get alive into the ditch by the side of the road, and so escaped to Woking. There his story became ejaculatory. The place was impassable. It seems there were a few people alive there, frantic for the most part and many burned and scalded. He was turned aside by the fire, and hid among some almost scorching heaps of broken wall as one of the Martian giants returned. He saw this one pursue a man, catch him up in one of its steely tentacles, and knock his head against the trunk of a pine tree. At last, after nightfall, the artilleryman made a rush for it and got over the railway embankment.

Since then he had been skulking along towards Maybury, in the hope of getting out of danger Londonward. People were hiding in trenches and cellars, and many of the survivors had made off towards Woking village and Send. He had been consumed with thirst until he found one of the water mains near the railway arch smashed, and the water bubbling out like a spring upon the road.
