The Devon men now had things all their own way. The "U" boat could not dive with her conning-tower hatchway in a damaged condition, or she would fill and sink like a stone. Nor could the trapped Huns use their rifles and revolvers. One foolhardy man attempted to take a chance shot through the after-hatchway, but directly his hand appeared above the coaming, Peter smashed it to a pulp.

The state of affairs now developed into a deadlock. The submarine could not escape, nor could the British fishermen regain their craft without risk of losing the advantage they at present held.

At this juncture the crew of the "Unity," perceiving that Skipper Hunnable was putting up a fight, but ignorant of how matters stood, determined to go to their comrades' aid, and sink or swim in the attempt.

Luffing smartly under the submarine's submerged stern, Skipper Biddlecombe brought the "Unity" up on the "U" boat's starboard side and made fast.

"What be you a-shovin' your five eggs in for, I'd be likin' tu know?" was Skipper Hunnable's greeting to the newcomers.

"No offence, Charlie," replied the fellow-skipper. "Us don't get the chance tu fight the Huns every day."

"True, true," rejoined the master of the "Crown and Sceptre." "You'm handy just now. Bid young Jack bring a shovelful o' coals and a bit o' junk. We'll have to be smokin' them chaps out, I'm thinkin'."

Ignorant of the risk they ran, the fishermen were about to throw smouldering tow down the hatchways into the petrol-laden atmosphere of the interior of the submarine when the Germans, realising the fate that threatened them, began to raise shouts of "kamarade."

"Thought better of it, eh?" said Skipper Hunnable. "Douse them coals, Jack. Now, you rascals, up you come. Four o' you. Drat you! I said four o' you. One, two, dree, four—not a round dozen. That's better. Now, hands up, an' keep 'em up. Rest o' you chaps below there are you a-listenin'?"

"Ja, ja!" was the reply.
