It lacked two hours of daylight when they arrived in Richmond. They took a taxi across town to the Chesapeake and Ohio station, where they caught a train for Newport News an hour later. At eight o'clock they were in Newport News, and fifteen minutes later stepped aboard the Essex.

"Glad to see you back, sir," said Lieutenant Hetherton, who held the deck.

"I suppose you've heard----"

"Pipe all hands to quarters, Mr. Hetherton," Jack interrupted sharply, "and clear ship for action. We sail within the hour."

Lieutenant Hetherton hurried away.

"Frank," said Jack, "go below and have a look at the engine room. Then find the quartermaster and see about provisions and fuel."

Frank also hurried away.

Sailing preparations aboard the Essex were made hurriedly and within less than an hour all was ready for departure. Meanwhile, crowds had collected ashore, upon learning that the Essex was about to set out in pursuit of the German undersea raiders.

Loud cheers split the air. Men and women waved their handkerchiefs. From a group of soldiers on the shore came expressions of good luck. In response to Jack's request, a pilot had been hurried aboard and now took the wheel.

"Half speed ahead," Jack ordered.

The water churned up ahead of the Essex, and she moved majestically toward the center of the stream.

Gradually the cheering died away in the distance, and the city of Newport News was lost to sight. In Hampton Roads again, the pilot was dropped in a small boat and rowed shoreward.

Frank took his place behind the helmsman and Jack rang for full speed ahead. At last the Essex was off in pursuit of the German submarines.

Meanwhile, an account of the activity of the enemy off the coats is in order. Besides the sinking of the first two freight vessels, which had been reported to the Navy Department by survivors who had reached shore in small boats, other vessels had been sent to the bottom. Most of these were freighters or small trading ships, including two sailing vessels. Some had been sunk off the New Jersey coast, others off the coasts of Delaware and Virginia.

In some cases the vessels attacked had attempted to flee, but they were quickly overhauled by the submarines, which, besides firing torpedoes into their hulls, shelled them with rapid fire guns and later attacked the small boats in which the crews sought to make the shore.

Casualties had been heavy aboard the ships sunk by the raiders. One or two of the enemy submarines had been fired on by armed ships, but to no avail; and as a result of those efforts, the death lists aboard such vessels had been increased, for the Germans, angered, had swept the survivors in small boats with rapid fire guns.

How many submarines were operating in American waters, the Navy department did not know. From the fact that ships were attacked in at least three places, within a short space of time, however, it was believed that there were at least three or four of the raiders.

From all ports along the coast, destroyers, submarine chasers, motor boats armed with single guns, had put to sea in an effort to run down the raiders. But off the New Jersey coast, almost in the midst of these vessels, a sailing ship was sunk by a submarine. Before any of the patroling vessels could reach the scene, however, the U-Boat had submerged and fled.

Depth bombs were dropped by ships of war wherever it was thought a submarine might be lurking beneath the water. But these efforts met with no success. Reports of sinkings in other parts of the water reached the Navy department.

The first sinking was reported on May 10. In the week that followed, eighteen other vessels were sent to the bottom by German submarines off the American coast. At the end of that time, however, the waters were being so well patrolled that it would have been suicide for a submarine to have showed itself.

Reports of sinkings ceased. But, from time to time, word was received that submarines had been sighted farther south, first off the coast of the Carolinas and then off Florida. No attacks were made in these waters, however, and the next that was heard of the submarines they were off the coast of South America.

During the activities of the enemy raiders, one submarine was sunk, and one was captured, both through the efforts of Jack and the crew and officers of the Essex.

After leaving Hampton Roads, the Essex steamed out beyond the Virginia Capes. Immediately Jack sought to get into communication with Admiral Sellings by wireless. And at last he raised the admiral's flagship, the Dakota.

"What do you want?" came the query from the Dakota, after Jack's flash had been picked up.

"British destroyer Essex, Captain Templeton, reporting to Admiral Sellings for orders at the request of Secretary Daniels," was the message Jack sent back.

"One moment," was the reply.

Jack waited in the radio room aboard the Essex.

"Essex! Essex!" came the call five minutes later.

"Answer," Jack directed the operator.

"Essex replying," the operator flashed.

"Admiral Sellings orders Essex to proceed north and stand out to sea to protect inbound vessels. Understand one submarine sighted five miles out five hours ago. Repeat."

The operator repeated the message to show that he had caught in correctly.

Jack went on deck and gave instructions necessary to putting the Essex out at sea. Then, "Full speed ahead!" he signalled.

The British destroyer Essex stood out to sea magnificently. Aboard, her crew stood to their posts, ready for action. Jack, surrounded by his officers, held the bridge.

"We've got to keep a sharp eye out," said Jack.

"Right," Frank agreed. "We're likely to come upon one of the enemy any moment, and we can't afford to let him see us first."

"Very true, sir," Lieutenant Hetherton agreed. "Fortunately all our lookouts have sharp eyes. I'll venture to say a submarine won't come to the surface very close to us without being seen."

"That's the way to talk, Mr. Hetherton," said Jack. "It shows the proper spirit."

"And the men are imbued with the same spirit," declared Frank, "and yet see how cool they are."

It was perfectly true. There was no confusion aboard the Essex in spite of the fact that each member of the crew knew he was bent on a dangerous mission. One shot from the submarine, they knew, if truly aimed and Jack was unable to maneuver the vessel out of harm's way, would be the end.

However, like all British tars, they had absolute confidence in their commander; for, according to their line of reasoning, if he were not a capable officer and to be depended upon he would not be in command of the ship.

Suddenly the radio operator appeared on deck and hurried toward the bridge. Jack stepped forward to meet him. The lad took the message the operator passed him and read:

"S.O.S. Pursued by submarine eighteen miles off Cape May light.

Am running south by west, but foe is gaining. Capt. Griswold, Ventura."

"This," said Jack quietly, "means that there is still another U-Boat to be reckoned with, but I had no idea they were operating so far out. We'll have to get busy."

Jack looked at his officers with a slight smile on his face, then ordered: "Shape your course due east, Frank. Full speed ahead."

CHAPTER XIV

THE U-87

As the Essex sped forward the radio operator from time to time picked up other messages from the Ventura.
