We slept in snatches of minutes, until the cold awoke us again, and again sent us dancing or scouting about. It was the most miserable camp we had yet experienced, but the safest, and the one where we were the least thirsty. There was more water about us than was altogether desirable, we thought at the time. Twenty-four hours later, looking back, we altered our opinion. The distance from this camp to the Dutch frontier was five miles to the west-northwest, as the crow flies. Opposite to us the border traversed an extensive swamp, the Bourtange Moor, twenty-five miles in length, and between five and seven miles in width. According to our map, neither road nor path led over it, which was one of the reasons why we had selected it as the point to strike at. “Information received” had encouraged our belief that the swamps which extend along nearly the whole of the northern frontier between Holland and Germany can be traversed in summer and autumn during normal years. Other information tended to show that comparatively they were negligently guarded. I had never forgotten a newspaper article which I had read in Ruhleben in the winter of 1915-1916. A territorial had described his duties as a frontier guard. There was one passage: “When on duty I shared a small hut with another man.… We had to walk two hours to the nearest post.” Two men to guard a two-hours’ stretch! Ridiculous! Camouflage! but still-- Our route would be across the northern half of the moor. I had talked it over with my companions many a time. “There is this large forest at the north end of the swamp. If the recent rains have made the swamp impassable, we’ll have to make for it and try to cross the frontier where it runs through the wood. I should hate to have to do that. A hundred to one, sentries there will be as thick as flies in summer. But we may have no alternative. For that eventuality, we will take the most favorable course across the swamp, walking west by north. Since we must continually go round bad places, we will make all corrections northerly, and thus edge off toward the wood, and lessen the distance in that way. “These two roads, parallel to the river, which we shall have to cross before getting on to the swamp proper, will be dangerous. I shouldn’t wonder if sentries and patrols were to be found on them. But I cannot imagine how they can easily relieve a man on a trackless morass; can you?” At 5:30 we ate our last meal. A very slender one it was. We reserved only some chocolate and the tin of Horlick’s malted milk tablets, which we always had looked upon as our emergency ration. These we divided into equal shares. At 5:45 I advised the cutting of long, stout staves. They would be useful, I thought, for the work ahead of us. I had no idea that they would make all the difference between failure and success. At 6 o’clock we could not stick it any longer inside the thicket. We made our way out, and walked up and down behind the bushes, waiting for darkness.
