In view of the fact that the scene of the first shock with the enemy was fixed by necessity and not by choice, the Mons canal may be considered as a fortunate feature in the landscape. It ran sufficiently true to the required line to offer an obvious line of defence, and an ideal one, except for the flagrant defect that, after running from Condé to Mons in a mathematically straight line, on reaching the town it flings off to the north in a loop some two miles long by one and a half miles across. This loop, as well as the straight reach to Condé, was occupied by our troops. The formation of the British army, then, was not only that of a broad arrow, but of a broad arrow with a loop two miles long by a mile and a half across projecting from the point. Such a position could obviously not be held for long, and Sir Horace Smith-Dorrien, recognizing this, had prepared in advance a second and more defensible line running through Frameries, Paturages, Wasmes and Boussu. To this second line the troops were to fall back as soon as the salient became untenable. A glance at the map will serve to show that the effect of swinging back the right of the 2nd A.C. to this new position would be to at once bring the whole British Army into line, with a frontage facing the advance of the enemy from the north-east. In view, however, of the preparedness of the Germans and the comparative unpreparedness of the Allies, time was a factor in the case of the very first importance, and therefore the passage of the canal had to be opposed, if only for purposes of delay. It is important, however, to keep in mind that the real line which it was intended to defend at Mons was this second line. The intention was never carried out, because it was anticipated by an unexpected and most unwelcome order to retire in conformity with French movements on the right, which upset all plans. In the meanwhile, the enemy's entry into Mons itself had to be delayed as long as possible, which meant that the canal salient, bad as it was, had perforce to be defended. This dangerous but most responsible duty was entrusted to Sir Hubert Hamilton with his 3rd Division, and, as a matter of fact, the battle of Mons in the end proved to be practically confined to the three brigades of this division. The disposition of the division was as follows: General Shaw, with the 9th Brigade, was posted along the western face of the canal loop, his right-hand battalion being the 4th R. Fusiliers, who held the line from the Nimy bridge, at Lock 6, to the Ghlin bridge. To the left of the R. Fusiliers, were the R. Scots Fusiliers, and beyond them again half the Northumberland Fusiliers reaching as far as Jemappes. The Lincolns and the rest of the Northumberland Fusiliers formed the reserve to the brigade and were at Cuesmes in rear of the canal.
