Hugh M. Cole, The Ardennes: Battle of the Bulge… (1965)
“ Just as the Moselle vineyards of renown alternate from one bank to the other, so the railroad line and the highway crisscross the river throughout its middle reaches; but rail and road come to a focal point only a few kilometers from the Luxembourg frontier at the old Roman city of Trier. Throughout this whole area military routes of movement, regardless of the weather, are synonymous with the road system. The roads of the Ardennes proliferate in accordance with the geological compartments incised in the high plateau by rivers and streams as they recede downward. ”
