Early one morning the "Vorwartz," running light, brought up between the breakwaters that, extending nearly two miles from shore, mark the Mediterranean entrance to the Canal. Here, landing a party of armed men, he took possession of the two lighthouses, and terrified the lightkeepers into submission. He compelled them to ascertain by telegraph what vessels had entered the canal during the previous twenty-four hours and what were expected. Finding that there were no armed ships between Port Said and Suez, and none within easy steaming distance of the latter port, he resolved upon the desperate enterprise of passing through at full speed. To keep submerged would mean loss of time and possibilities of running aground in the Bitter Lakes. Thus, almost before the Canal authorities at Port Said recovered from their astonishment that a strangely-constructed vessel should have passed into the Canal at several knots above the regulation speed and without paying the customary dues, the "Vorwartz" was well on her way to Ismalia. In the Little Bitter Lake her luck deserted her, for in attempting to pass a lumbering Dutch tramp steamer, the "Vorwartz" struck upon the sand on the west side of the Canal. Meanwhile the telegraph had not been idle. It was rightly conjectured that the mysterious craft was that of the modern buccaneer, and a battery of Egyptian artillery had been ordered from Cairo. The artillerymen were sent by train, the route being so roundabout that several hours elapsed before the men and guns detrained at the nearest station, where they were separated by a fresh water canal and a stretch of desert from the spot where the "Vorwartz" had grounded. It was fortunate for the ’Gippy artillery that Karl von Harburg did not possess the same potential means of offence as did the captain of the "Aphrodite," otherwise the charged shells in the limbers might have exploded with disastrous results. Eventually, after great exertion, the blacks got their guns into position and prepared to hull the helpless submarine. Just then a heavy sandstorm swept down. The breech-blocks of the quick-firers had to be promptly covered up to prevent the ill-effects of the sand upon the delicate mechanism. When the storm ceased the "Vorwartz" was once more afloat and hidden by the sand hills. Only one course remained for the British officer in charge of the Artillery to take. That was to regain the railway and entrain for Suez, where another chance of cutting off the submarine’s retreat was left. But once again the troops were foiled, for before they reached Suez, the "Vorwartz" had passed Port Ibrahim, the Red Sea entrance to the Canal.
