To the strategical reasons which induced the Germans to throw the chief force of their attack in the first place against the right of the British line to the west of Lille, reference has already been made, and those reasons are sufficiently clear. The reasons which induced the Germans to shift it to the south and south-east of Ypres are not so obvious. Indeed, the only acceptable explanation is that their severe defeat on October 24 caused such discouragement that the plan of forcing the right of the British position was given up as impracticable.

In order to reach Ypres from the south it was necessary to win the ridge, while to reach Ypres from the east it was necessary to penetrate the almost continuous belt of woods. These woods presented an obstacle which made the organisation of the huge mass attacks, in favour with the reigning school of German tacticians, almost out of the question. Sir John French as we have seen took advantage of these features of the country skilfully to economise his force, and at the same time to conceal that fact and mislead the enemy. The Germans it is evident had by October 26 found out their mistake. They discovered that west of Lille they had been running their heads against a stone wall, and deceived by the aspects and features of the country, had been neglecting what they now considered had been a comparatively easy entrance.

When they changed their plans, however, they made yet another mistake—that of thinking or rather of presuming that the British dispositions would remain unaltered.

Through the woods to the east of Ypres there is one great main road. Beginning at Menin—that town is just on the Belgian side of the French frontier—this broad, well-paved highway runs nearly straight as an avenue into Ypres.[9] The distance is ten miles. From Ypres the great road is continued towards the coast until at Furnes it joins on to the great road which runs along the coast from Ostend through Nieuport, Dunkirk, and Gravelines to Calais.

The importance of Menin lay in the fact that not only do several lines of railway branch out from that place southwards into France, including the railways to Lille, which is not more than ten miles away, but that it was the starting-point of this great road. Ypres again is the starting-point of a converging great road to Dunkirk. It may be remarked generally that the great main roads of Flanders run across the country from inland to the sea, and not along the country parallel with the sea. There are certain nodal points in this road system. In West Flanders, Ypres is the chief of those points. If we study the disposition of the Allied forces at this time with reference to the lines of communication, it will be seen both that they barred access to Ypres, and that west of Lille they were astride of, and therefore rendered useless to the enemy, the main line of railway from Lille to Calais. On that line Bailleul, Hazebrouck, and St. Omer are alike situated. The German advance, checked and thrown back by the unexpected appearance of the British from the Aisne, was an advance intended both to master the main line of railway, and the road system.

For a distance of some three miles the avenue from Menin to Ypres runs through the belt of woods. Six miles from Menin and four from Ypres it passes through the village of Gheluvelt, cresting there the ridge of hills. A mile to the east of Gheluvelt, and five miles from Menin, a road branches off the main avenue to Werwick on the Lys, and, on the opposite side of the avenue here there is a cross-road of no great consequence, save that it serpentines northward through the belt of woodland until it joins the main road from Ypres to Bruges. Trivial, therefore, as a public way, this cross-road was of considerable military value, since it gave access to some five miles or more of the woods.

It may be added that just by these cross-roads, east of Gheluvelt, there is a small outer ridge or rise called the hill of Kruyseik, after the village of that name lying in the hollow, and that over the main crest at Gheluvelt, and between that point and Ypres there is another rise or ridge. Behind this, on the side towards Ypres, lies the village of Zillebeke. Across the hills, again, to the south of Ypres and between that city and the Lys, there are two somewhat zigzag minor roads. The first of these passes through the village of Zandvoorde, and the second through the village of Hollebeke. Then further west we come to the main road running due south from Ypres to Armentières. Along this road, some two and a half miles out of Ypres, is St. Eloi, and two miles farther on Wytscheate.

These topographical details may appear minute, but they have to be understood because they show that, to get into Ypres from the south and south-east, the Germans had as lines of attack these four routes: the main avenue from Menin; the road through Zandvoorde; the road through Hollebeke; and the road through Wytscheate and St. Eloi; and it will be found that in fact their attacks were made along those lines.

Shrewdly foreseeing such a development of the battle, Sir John French, on October 27, unified the immediate command of the troops on his eastern front by adding them to the 1st Army Corps. They were redistributed in order to meet the probable weight of the coming assault which was almost certainly to be looked for along the main avenue from Menin. The line, in fact, was tightened up.

The 7th Division was disposed along a line some two miles in length from Zandvoorde to the Menin avenue, and held the Hill of Kruyseik.
