To Staff-Captain Nuyten, assisted by Charles Louis Kogge, a "wateringue" guard of long experience and thoroughly acquainted with the working of the system of canals and locks, was entrusted the task of carrying out the plan. The plain between Dixmude and Nieuport, being level with the sea, is protected at Nieuport against high water by a system of locks (sketch opposite). The canals and the Yser are dammed by embankments. The railway itself runs along a wide straight dike three to six feet in height. Under bombardment, Belgian Engineers transformed this railway embankment into a water-tight dike, by stopping up all the openings through which the roads passed and then made wide breaches in the embankments of the drainage-canals, so as to allow the water to spread. The whole plain, between Nieuport and Dixmude was thus transformed into a vast basin closed on the Belgian side by the railway embankment, the latter being at the same time organized as a line of resistance. Certain locks were secretly opened at high-tide, through which the sea gradually and imperceptibly invaded the basin. While the sea was thus preparing to play its all important rôle, a fresh enemy attack forced the Franco-Belgian troops, on the 26th, to withdraw behind the railway. Orders were given to hold the latter at all cost. Nieuport and Dixmude were still holding out. At Dixmude, two battalions of Senegalese relieved the most exhausted units of the defenders. Behind the railway, units of the 42nd Division and a few battalions of Territorials supported the desperate efforts of the Belgians. On the 26th and 27th, while the bombardment continued, the water began, little by little, to invade the trenches of the enemy, who, however, did not yet realise the position. On the 28th, the water began to rise and, on the 29th, spread southwards. An extremely violent bombardment on the 29th preceded the German attacks of the 30th, against the railway. Thanks to their _minenwerfer_, the Germans gained a footing on the railway, and advanced as far as the villages of Ramscappelle and Pervyse. It was a critical moment, the main line of resistance being pierced. [Illustration: +Fortified Embankment at Ramscappelle.+] The defenders pulled themselves together for a last effort, and after a violent concentration of artillery fire, counter-attacked. On the 31st, at nightfall, the 42nd Division and Belgian units--remnants of battalions belonging to the 6th, 7th and 14th line regiments--charged furiously with the bayonet, to the sound of the bugles. The enemy was thrown into disorder, Ramscappelle recaptured, and the line re-established. Imperceptibly but relentlessly the floods invaded the enemy's entrenchments, turning their retreat into a rout; their dead, wounded, heavy guns, arms and munitions were swallowed up in the huge swamp. The Battle of the Yser was over.
