However, no sooner did the bow gunners take their dose of death and spill into the water than a new crew popped up out of the conning tower hatch and scurried forward to replace them. Others also popped up into view, each armed with a portable machine gun. They dropped in back of the conning tower bridge for what protection it would afford them and began blazing away. Dave felt the Albacore shake and tremble a little as a well placed burst went tearing up through the right wings. But he didn't swerve from his straight downward plunge a hair. He and Freddy would have to risk the machine gun fire. It was the bow guns he had to put out of action. Rather, he had to send the second crew spilling off after the first. Let those two guns get in their licks and the Albacore would be a mess of metal toothpicks flying about in the air.
And so Dave held the plane steady and tore down until it looked as though he were going to dive right into the bow mounted guns. In the last instant allowed he let fly with his guns, practically tore the new gun crews to bleeding shreds with his deadly fire, and went curving upward and around to give Freddy Farmer a point blank shot at the half crouching machine gunners. And the English youth didn't waste a split second, or a single shot from his twin guns. His fire was every bit as deadly as Dave's, and it knocked over the crouching machine gunners like a shotgun would knock over frozen birds perched on an icy telephone wire. The little Japs went down like ten pins. And what's more, they stayed down!
Then, suddenly, as Freddy Farmer let drive with a parting burst, a column of orange red flame came shooting up out of the open conning tower. It leaped three hundred feet straight up into the air and then blossomed out on all sides like a gigantic flower of fire. At almost the same instant invisible giants down in the depths of the shimmering blue water seemed to push upward against the keel of the submarine. The whole craft rose clear out of water, seemed to hover motionless for a split second, and then buckle in the middle and fall back in again. White spray, red flame, and boiling smoke spread out in all directions. And then presently there was nothing but an ever widening oil slick on the water to indicate the spot where the submarine had gone down for good.
Struck speechless by the weird, horrible sight, both boys stared frozen eyed for a long moment. Then Dave shook himself out of his trance and hauled the Albacore off the top of its zoom. Once the plane was level he twisted around and grinned at Freddy.
"What was that about not having depth bombs, or aerial torpedoes?" he echoed. "Boy! With you around to shoot right down the open conning tower and touch off something in her innards, we don't need anything else. Nice going, pal! That gets you a kewpie doll, or something."
"Think what it gets me, if British High Command ever finds out!" Freddy Farmer said in a tight voice. "Good Lord, Dave! I've just sunk a Japanese submarine, and...."
"Yeah, I know!" Dave cut in sharply. "England's not even at war with Japan ... yet! The big shots in London and Tokio haven't made it official, yet. Lot of good that did us yesterday, didn't it! And a lot of good it did those poor devils aboard the courier plane! Nuts! You and your traditional rules of war give me a pain in the neck. Wake up, little man. That sort of thing is all changed these days. Nowadays you hit first, you hit hard, and you hit for keeps! If you don't you're going to find yourselves waking up in a hospital ... if you do wake up!"
"Yes," Freddy Farmer mumbled and swallowed hard. "Yes, of course you're dead right. But, it gives a chap a queer feeling just the same. I mean, if that had been a Nazi U-boat, why...."
"Who says a Nazi wasn't her commander?" Dave snapped. "Jap, Nazi, or one of Mussolini's funny looking things! Who cares? It's down where it belongs, now. And down to stay. And I still say that was sweet shooting, sonny boy. Sinks a sub with a couple of machine guns. No, I guess we'd better not ever report it. Nobody would ever believe us. We'd be called a couple of first class.... Omigosh!"
"What's the matter?" Freddy Farmer cried in alarm as Dave stiffened and jerked his head front. "Another one?"
