The English army was ready to go to war. It was ready to go to war in Belgium. Its officers knew everything there was to be known about Belgium. They knew every square mile of Belgium's terrain. They knew what districts were best suited to strategical purposes. They knew what roads best to use for their artillery, what roads best could stand the heavy guns, what roads best could not. They knew every body of water in Belgium. They knew what water was fit to drink and what was not. They knew the current of every stream and the number of boats on it. They knew the number of houses in every Belgian village and the number of soldiers that could be billeted in those houses. They knew the location of every church steeple in Belgium, and whether or not to recommend it as an observation post. They knew what roads their troops could march on without being seen by the aviators of the enemy—what roads were hidden from the sky by the interlacing branches of the big trees. They even knew the best places for their own aviators to land. Every conceivable thing that a modern army should know about a future battleground the British army knew.... How do I know this?

At the battle of Mons in northern France where something happened—the English say it was the French supports; the French blame it on the English—those wonderful soldiers of Great Britain, the professional soldiers, were cut to pieces. The Germans made many prisoners. In the kits of the captured British officers they found some interesting documents. They were books of a size that would fit in a coat pocket. They were about a quarter of an inch to an inch thick. They were printed on white paper and the covers were a light brown. They were finger-marked and muddy. They contained the most amazing collection of military information that any nation ever possessed for its army. Some books were marked Confidential; others bore the designation property of His Britannic Majesty's Government; all were prepared by the General Staff, of the English War Office.

All the books were dated 1914, brought right up to the minute. At the Great General Staff in Berlin I saw these books. I sat in Major von Herwarth's room one night and copied their contents until I was overwhelmed with their wonderful detail. I had wanted to take the books to my hotel. It was impossible. They were regarded by the Germans as being so valuable that they could not be taken from this officer's room. I induced the Staff to let me make photographs of the books, of their covers, pages and maps. And when I was finished the officer said to me, "We were very glad to get these books. We were very thankful. Because they are so much better than any information that our General Staff had about Belgium. In fact they are so good, these English books, that we at once had whole pages copied for the use of our officers in Belgium."

The Germans admitting English superiority on a military point! Germany, whom everybody thought was the best prepared nation in Europe, beaten at its own game. So valuable are these books regarded by the General Staff that they are locked in a safe.

As I digested the contents of these English books, I decided that if I had military power behind me, and these books in my pocket, that I could walk, ride, even fly in Belgium—without ever having been there before. I could always know precisely where I was at, where I could best be housed. I saw that each book begins with "roads," and reports the widths, surfacing and nature of the ground on either side of these roads. Every conceivable bit of information about the railroads in Belgium is between the covers, even down to the station masters at small places and the language each one speaks. Rivers, canals, bridges, dikes, have all been tested by the unprepared Englishmen. I thought now English cavalrymen were interested in learning that, "in the village of Eppeghen there are three forges." On another page I learned that "a kindly feeling exists for England because of a school for English children." In Tamines, "a large number of Germans are employed in the electrical work." On page 17 of Volume Two, I read "the farms ... are large solidly built structures, the barns usually being lofty with high eaves. The two storied dwelling houses enclose a barnyard. The Howitzer is the weapon of attack against them and the folds in the ground facilitates its use." Under "Monetary Contributions"; I read, "It may be necessary under certain conditions in an enemy's country to replace supply requisitions in kind by contributions in money."

And the English blame the Germans for their levies in captured cities. In the upper right hand corner of Volume Three, I saw what seemed to be a serial number—349. The other volumes also bore this number. Volume III declares itself to be a report on road, river and billeting conditions in Belgium; it gives information for the country between the river Meuse and the German frontier, going as far south as certain designated military lines. Glancing over this book, I saw on page 20 that the district near the German frontier was particularly suitable for billeting soldiers, that three or four men could be housed with every inhabitant except in Seraing and Liége where only two soldiers could be put up. On page 232 I learned that the billeting report had been reconnoitered every year from 1907 to 1913. This means that in the district covered by this book every dwelling place with a roof over it had been checked up every year for seven years. Thus were proper living accommodations for English soldiers in Belgium verified by the skilled War Office of London.

In Volume IV which gave all military routes for Belgium north and east of the line Brussels, Nivels, Namur, Liége, Vise, I read on page 13 that the reference maps dealing with the section "Brussels-Louvain" were those of the Belgian General Staff of a scale 1/40,000 but that sheets 31 and 31 of the English War Office were also available. Those English sheets were based on a reconnoiter of the entire district made in 1913 by the English. But more significant is it that English officers were referred to the 1/40,000 scale maps of the Belgian staff, which England obviously must at that time have had—as an asset of preparedness.

In the German General Staff I had a number of these English maps photographed. They were drawn by the British War Office and photo-etched by the Ordnance Survey office at Southampton 1912. As you may see from the accompanying illustration their detail is marvelous. Even orchards, ruins and wind mills are designated.

A Staff Officer in possession of one of these books would not have to reconnoiter Belgium. Referring to Volume IV, which devotes a good deal of space to the movement of troops, he would learn that delays in marching might be caused by "a steep ascent for half a mile out of Brussels on the road to Louvain." He would be comforted to know, though, that "there is a good field of fire and fine view from the roadway except between Cortenberg and Louvain where the view is reduced to one half mile. Troops could operate easily anywhere except in the hilly wooded country about Cortenberg to the south." If he wanted an observation post he would learn that at Cortenberg there was a good church steeple. A footnote reassures him that the roadway has been lined with trees which would afford in summer cover from aerial scouts.
