Convinced that some misunderstanding of this kind had taken place, the Staff, still quartered at the Caeskerke railway station, shouted to the sections to cease firing. As, however, the fusillade continued in the direction of the town, the Admiral sent one of his officers, Lieutenant Durand-Gasselin, to reconnoiter. He got as far as the Yser without finding the enemy; the fusillade had ceased; the roads were clear. He set out on his way back to Caeskerke. On the road he passed an ambulance belonging to the brigade going up towards Dixmude, which, on being challenged, replied: "Rouge Croix." Rather surprised at this inversion, he stopped the ambulance; it was full of Germans, who, however, surrendered without offering any resistance. But this capture suggested a new train of thought to the Staff: they were now certain that there had been an infantry raid upon the town; the Germans in the ambulance probably belonged to a troop of mysterious assailants who had made their way into Dixmude in the night and had vanished no less mysteriously after this extraordinary deed of daring. One of our covering trenches must have given way, but which? Our allies held the railway line by which the enemy had penetrated into the defences, sounding the charge.... The riddle was very disturbing, but under the veil of a thick, damp night, which favored the enemy, it was useless to seek a solution. It was found next morning at dawn, when one of our detachments on guard by the Yser suddenly noticed in a meadow a curious medley of Belgians, French Marines, and Germans. Had our men been made prisoners? This uncertainty was of brief duration. There was a sharp volley; the sailors fell; the Germans made off. This was what had happened! Various versions have been given of this incident, one of the most dramatic of the defence, in the course of which the heroic Commander Jeanniot and Dr. Duguet, chief officer of the medical staff, fell mortally wounded, with several others. The general opinion, however, seems to be that the German attack, which was delivered at 2:30 P.M., was closely connected with the surprise movement attempted at 7 o'clock in the evening on the Essen road and so happily frustrated by the intervention of the Gamas company. It is not impossible that it was carried out by the fragments of the force we had scattered, reinforced by new elements and charging to the sound of the bugle. This would explain the interval of several hours between the two attacks, which were no doubt the outcome of a single inspiration.
