Fritz, in the air, liked to have the odds with him, as a rule.  It was exceptional to find a German flyer like Boelke who really went in for single-handed duels in the air.  As a rule they preferred to attack a single plane with half a dozen, and so make as sure as they could of victory at a minimum of risk.  But that policy did not always work—­ sometimes the lone British flyer came out ahead, despite the odds against him.

There was a good deal of firing on general principles from Fritz.  His shells came wandering querulously about, striking on every side of the battery.  Occasionally, of course, there was a hit that was direct, or nearly so.  And then, as a rule, a new mound or two would appear in the little cemetery, and a new set of crosses that, for a few days, you might easily enough have marked for new because they would not be weathered yet.  But such hits were few and far between, and they were lucky, casual shots, of which the Germans themselves did not have the satisfaction of knowing.

“Of course, if they get our range, really, and find out all about us, we’ll have to move,” said the officer in command.  “That would be a bore, but it couldn’t be helped.  We’re a fixed target, you see, as soon as they know just where we are, and they can turn loose a battery of heavy howitzers against us and clear us out of here in no time.  But we’re pretty quick movers when we have to move!  It’s great sport, in a way too, sometimes.  We leave all the camouflage behind, and some-times Fritz will spend a week shelling a position that was moved away at the first shell that came as if it meant they really were on to us.”

I wondered how a battery commander would determine the difference between a casual hit and the first shell of a bombardment definitely planned and accurately placed.

“You can tell, as a rule, if you know the game,” he said.  “There’ll be searching shells, you see.  There’ll be one too far, perhaps.  And then, after a pretty exact interval, there’ll be another, maybe a bit short.  Then one to the left—­and then to the right.  By that time we’re off as a rule—­we don’t wait for the one that will be scored a hit!  If you’re quick, you see, you can beat Fritz to it by keeping your eyes open, and being ready to move in a hurry when he’s got a really good argument to make you do it.”

But while I was there, while Fritz was inquisitive enough, his curiosity got him nowhere.  There were no casual hits, even, and there was nothing to make the battery feel that it must be making ready for a quick trek.

Was that no a weird, strange game of hide and seek that I watched being played at Vimy Ridge?  It gave me the creeps, that idea of battling with an enemy you could not see!  It must be hard, at times, I think, for, the gunners to realize that they are actually at war.  But, no—­there is always the drone and the squawking of the German shells, and the plop-plop, from time to time, as one finds its mark in the mud nearby.  But to think of shooting always at an enemy you cannot see!
