Tom was as proud of his machine as a general could be of his horse, and he wheeled it along beside him, keeping pace with the slow advance of his companions, his heart beating high. "If you have to come back with any message, you'll remember Headquarters, won't you?" one asked him. "I always remember Headquarters," said Tom. "And don't get rattled." "I never get rattled." "Watch the roads carefully as we go, so you can get back all right. Noise don't bother you?" "No, I'm used to artillery--I mean the noise," said Tom. "You probably won't have much to do unless in an emergency. If Fritzie cuts the wire or it should get tangled and we couldn't reach the airmen quick enough you'd have to beat it back. There's two roads out of Cantigny. Remember to take the south one. We're attacking on a mile front. If you took----" "If I have to come back," said Tom, "I'll come the same way. You needn't worry." His advisor felt sufficiently squelched. And indeed, he had no cause to worry. The Powers that Be had sent Thatchy into the West where the battle line was changing every day and roads were being made and destroyed and given new directions; where the highway which took one to Headquarters one day led into the lair of the Hun on the next, and all the land was topsy-turvy and changing like the designs in a kaleidoscope--for the very good reason that Thatchy invariably reached his destination and could be depended upon to come back, through all the chaos, as a cat returns to her home. The prison camps in Germany were not without Allied dispatch-riders who had become "rattled" and had blundered into the enemy's arms, but Thatchy had a kind of uncanny extra sense, a bump of locality, if you will, and that is why they had sent him into this geographical tangle where maps became out of date as fast as they were made. The sun was not yet up when they reached a wider road running crossways to the one out of the village and here many troops were waiting as far up and down the road as Tom could see. A narrow ditch led away from the opposite side of the road through the fields beyond, and looking up and down the road he could see that there were other ditches like it. The tanks were already lumbering and waddling across the fields, for all the world like great clumsy mud turtles, with soldiers perched upon them as if they were having a straw ride. Before Tom and his companions entered the nearest ditch he could see crowds of soldiers disappearing into other ditches far up the road.
