Careful preparations had been made for this night raid. It was the constant effort of both sides, during the period of trench fighting, to get possession of facts which would allow successful attacks to be carried out later. And to do this it was needful to get close to the enemy’s line. By so doing, certain things might be overheard in the talk among the soldiers, or (for the results of the listening were uncertain) better still, was the capture of prisoners. Once they were taken back of the lines, questioned and searched, much of value might be obtained.

This, as a matter of fact, worked much better for the Americans than it did for the Germans. If the Huns did succeed in capturing, during a raid, some of our boys, they got little information from them about the units with which the boys of Uncle Sam were connected. Nor did the Huns learn much as to the strength of the forces opposed to them, except, perhaps, in the way of exaggeration.

“The American captive is more inclined to utter 97 the equivalent of ‘nothing doing,’” remarked Jerry, one day when discussing the matter.

On the other hand, the German prisoners captured, almost invariably, were glad that their fate had thus been ordered. They were sure of decent treatment, they were in no more danger of being killed and, more than anything else, they would be better fed than in their own trenches.

So it is no wonder they gave valuable information under the skilful questioning of the American officers. Still this information had to be carefully checked up before being acted on, as it would not do to run into danger as a result of what some Hun captive told.

“We are going out to try our luck,” explained the lieutenant who was to lead Ned, Bob, Jerry, and their comrades, numbering half a score, out on a night raid. “There’s a German dugout not far from here, and near by a machine-gun nest, and if we can get close enough to rush it, and capture those we don’t kill, we may make it possible for a big forward movement—if the information we get is of the right sort. So get ready. Gas masks, hand grenades—rifles will be in the way—automatic pistols, of course, and don’t forget to blacken your faces.”

This precaution was always taken by night raiding parties. The Germans adopted the habit of sending up illuminating devices, known as “star 98 shells,” at frequent intervals over No Man’s Land. This was to guard against a party of the enemy advancing on the trenches. The shells gave a very bright light, and nothing stands out more conspicuously in such a glare than a white face. So it was the custom to blacken countenances and hands when a night-raiding party went over the top.

It was not without a little feeling of nervousness and apprehension that the three friends and their chums made their preparations. But it was an apprehension of failure rather than fear. They wanted to succeed, to get results, and they were afraid they might fail. They were not afraid, personally. Still they were taking big chances, and they all knew it.

“Ought we to leave some word for Professor Snodgrass?” asked Ned, as he and his friends were making ready about midnight.

“Word about what?” Jerry inquired.
