"You may state that an army estimated by our airmen as being four corps strong is being forced in between the Fourth and Fifth Armies. Here is the dispatch."

"You'd better put on a French uniform."
"But I haven't the right—" Horace began.
The officer summoned an orderly.
"Have some one find a uniform for this boy," he said. Then, turning to Horace, he added, "I'll write you an order authorizing its use, as you are on special service."
Half an hour later a uniform was brought to Horace where he was busy oiling his machine and filling the petrol tank.
"Where did you get it?" the boy asked curiously.
