When I had finished and had carefully destroyed my first pencilled memoranda, the steady bumping of artillery passing through the street under the windows drew my attention.

It proved to be the expected batteries of the reserve going into park, between the two brigades of Raoult’s division of infantry. I telegraphed the news to the observatory on the Col du Pigeonnier, then walked back to the window and looked out.

It had begun to rain again; down the solitary street of Morsbronn the artillery rolled, jolting; cannoneers, wrapped in their wet, gray overcoats, limbers, caissons, and horses plastered with mud. The slim cannon, with canvas-wrapped breeches uptilted, dripped from their depressed muzzles, like lank monsters slavering and discouraged.

A battery of Montigny mitrailleuses passed, grotesque, hump-backed little engines of destruction. To me there was always something repulsive in the shape of these stunted cannon, these malicious metal cripples with their heavy bodies and sinister, filthy mouths.

Before the drenched artillery had rattled out of Morsbronn the rain once more fell in floods, pouring 7 a perpendicular torrent from the transparent, gray heavens, and the roar of the downpour on slate roofs and ancient gables drowned the pounding of the passing cannon.

Where the Vosges mountains towered in obscurity a curtain of rain joined earth and sky. The rivers ran yellow, brimful, foaming at the fords. The semaphore on the mountain of the Pigeonnier was not visible; but across the bridge, where the Gunstett highway spanned the Sauer, gray masses of the Niederwald loomed through the rain.

Somewhere in that spectral forest Prussian cavalry were hidden, watching the heights where our drenched divisions lay. Behind that forest a German army was massing, fresh from the combat in the north, where the tragedy of Wissembourg had been enacted only the day before, in the presence of the entire French army—the awful spectacle of a single division of seven thousand men suddenly enveloped and crushed by seventy thousand Germans.

The rain fell steadily but less heavily. I went back to my instrument and called up the station on the Col du Pigeonnier, asking for information, but got no reply, the storm doubtless interfering.

Officers of the Third Hussars were continually tramping up and down the muddy stairway, laughing, joking, swearing at the rain, or shouting for their horses, when the trumpets sounded in the street below.

I watched the departing squadron, splashing away down the street, which was now running water like a river; then I changed my civilian clothes for a hussar uniform, sent a trooper to find me a horse, and sat down by the window to stare at the downpour and think how best I might carry out my instructions to a successful finish.
