Late in the evening, hearing an unusual bustle outside, and the tooting of horns, they peered out, and saw a dozen goods vans coming across the compound. On investigation they learned that the last supply vans had not been molested in the least, but the first convoy to reach the field base the next morning was literally shot to pieces, two of the chauffeurs having been killed, several of the assistants severely wounded, and three of the vans completely demolished.
The supply station was less than a mile behind the lines, but it was well concealed behind a bluff on the western side of the little stream, and only occasionally would a shell find its way to that section. The precaution was taken by the commanding officer, to keep a score of airplanes above and near the camp and thus prevent the enemy from locating the spot.
During the following day they visited the trenches, not on account of the novelty, but more a matter of curiosity. On returning they crossed the stream and ascended an elevation, designated as Hill 207, where they inspected the battery and conversed with some of the gunners.
"The big Bobs are on the way," said the sergeant, in speaking of the preparations that were going on for the great drive.
"What do you mean by that?" asked Alfred.
"Oh, that's the term we use for the 75's," he replied.
"They are the fellows we must see," said Ralph, as they walked down the hill.
"When did that fellow say the 75's would come up?" asked Alfred the following morning.
"He said they were on the way now," answered Ralph. "Suppose we ask the boys."
Every one had heard of the famous 14th, which had done such terrible execution east of Marmelon. It was understood that they were to take up position along the ridge west of Hill 209.
