"By Jove!" exclaimed Tressidar. "They are German vessels."

He was right. There were three light cruisers steaming in line ahead. On either hand were lines of torpedo-boats, while overhead at an altitude of about one thousand feet flew two Zeppelins of the most recent type. The Huns, fearing submarine attack, were taking no unnecessary risks. They were cruising in neutral waters, but the German populace was not to know that.

"Keep your men well out of sight," cautioned the skipper. "Even the Norwegian flag flying in Norwegian waters would not be able to protect you."

As he spoke the leading torpedo-boat of the starboard division sounded her syren imperiously. By all the rules of the road at sea the tramp, being the overtaken vessel, was entitled to hold on her course; but it was evident that the German flotilla was attempting to edge the "Freya" beyond territorial waters, although for what reason none on board her could certainly conjecture.

Nearer and nearer drew the warships, without making the slightest attempt to alter helm. Their syrens were braying frantically. It reminded the sub. of a herd of cattle trying to shift a little dog that impeded their way.

If the "Freya's" skipper held on, he realised that he would give the imperious Huns cause for offence. Reluctantly he gave orders for the helm to be ported in order to yield to the palpably illegal tactics of the German ships.

As the tramp altered her course the starboard column of torpedo-boats did likewise, until they were heading south-east or almost at right angles to the coast-line. The "Freya" was being jockeyed beyond the three-mile limit.

The sub. knew that he and his men were in a tight corner. Should the tramp be compelled to hove-to there was no escape. They could not be passed off as passengers, since their names did not figure on the passenger list. Nor was the ship certified to carry any persons besides her officers and crew.

Tressidar dismissed the proposal that he and his men should hide in the hold. Searched the ship would certainly be, and he was not going to be ignominiously hauled out of the hold by a mob of Germans.

At length, in fact directly the tramp had passed the limit of territorial waters, the peremptory hail to stop instantly came from the nearmost German torpedo-boat, which promptly swung out of station and slowed down.
