Imperiously the midshipman signed to them to assist his companion out of the pitfall. This they did with extreme alacrity, prompted by fear of their supposed German officers. Having regained his temporary freedom, Dick, without any attempt at thanks, ordered them in German to replace the dislodged cover to the pit. One of the Turks understood sufficient German to know what was required; the squad set to work, while Dick and his companion unconcernedly walked off.
"We must trust to luck not to find a German in this section of the advanced trenches," said Dick as they drew well clear of the scene of their late misadventure. "We'll have to risk it, for there's no other way."
Cautiously picking their path between numerous rifle-pits and concealed machine-guns, the two fugitives made for a part of the defences where a gap appeared to exist between the trenches. Here men were hard at work under the direction of Turkish officers. The latter saluted as the supposed German officers approached, but made no attempt to converse with them. Instead they urged their men to greater efforts, as if everything depended upon satisfying their Teutonic masters in the art of war.
By this time the Allied air squadron had disappeared. Without sustaining injury, and having done considerable damage to Fort Medjidieh, the sea-planes returned to their parent ship, the Ark Royal. Once more the Turkish search-lights directed part of their activities to sweeping the surrounding country.
Arriving at the farthermost line of trenches, Dick coolly mounted the parapet and took a careful survey of their general direction and character. He noticed that they were extraordinarily deep and narrow, so that unless a shell actually pitched into a trench the danger to the Turkish defenders was comparatively small. Another matter which attracted his attention was the number of machine-guns. Not only were there dozens concealed a hundred yards or so to the rear of the foremost trenches, but the parapets of the trenches fairly bristled with these deadly weapons. Roughly, there was one to every five yards, each gun being protected by a heavy V-shaped shield. The Turks had thoroughly mastered the principles of modern warfare under European conditions, and the task of the Allied Expeditionary Force was to be a very stiff one.
The Sub and his companion quite realized the extreme risk they were running. To be captured in the disguise of German officers meant an ignominious death as spies, but their audacity completely disarmed suspicion. To all appearances they were zealously visiting the Turkish troops engaged in perfecting the landward defences.
After a lengthy survey Dick leisurely descended the low parapet, and, accompanied by the midshipman, strolled towards the soldiers engaged in erecting barbed-wire entanglements in front of the trenches and clearing away the brushwood that might afford cover to an attacking force.
Then, watching their opportunity, the twain walked steadily past the workers and gained the comparatively open country.
Since an attack was not for the present expected, no outlying pickets had been posted. On descending a slight irregularity in the terrain Dick and the midshipman found themselves out of the direct glare of the search-light, while every step took them farther and farther away from the scene of their captivity during the last six weeks.
"Which way now, sir?" asked Farnworth.
