And more of the large shells were falling, until there was an almost continuous roar of detonating high explosives. Unlike normal cannon that fired shells directly at a target, these mortars arched a giant missile high into the air, to plunge down almost vertically onto the target below. Battlements and walls that faced the enemy were no defense against this kind of attack.
But General Bagnell was not aware of this debacle. He, and all of his officers, had been blown to pieces by the third shell that had landed on the fort. He did not live to see either the destruction of his fort or the obliteration of the gun emplacements across the river by the fourth mortar ship. In thirty intense, destructive minutes, all of the defenses of the river at Tilbury had been destroyed. Even as the firing ceased, the first of the long line of ships nosed into sight around the bend in the river and moved, unharmed, toward London.
USS Atlas had been idling her engines to keep position in the river against the tidal current. When the mortar ships had ceased firing, her captain saw that the boat that had been shielded by the bulk of the Thunderer was now pulling away from her flank. Good. Admiral Farragut was transferring his flag to the Mississippi—and taking the Thames pilot with him. Everything was going as planned. As soon as the boat reached the ironclad, Captain Curtin ordered the engines slow ahead. Three blasts on her steam whistle signaled the rest of the waiting ships to follow her upstream. As they got under way, USS Mississippi surged forward, passing the slower cargo ship and taking her position in the lead. After the successful landings at Penzance, she had proceeded to the mouth of the Thames to join the attacking squadron. Now she raced ahead, guns loaded and ready, to seek out any other river defenses.
Beside Curtin on Atlas's bridge, General Sherman looked at the smoking ruins of Tilbury Fort as they moved slowly by. "Utterly destroyed in less than half an hour," he said. "I have never seen anything like it."
Curtin nodded understandingly. "That is because you are a soldier and see war as something to be fought on land. But you must remember the success of General Grant's mortar ships in the Mississippi at Vicksburg. No railway gun can match one of these sea-battery mortars for size—and no team of horses could ever move one. But put them into an iron ship and you can cross oceans with them. Just as they have done. But it took the genius of a nautical engineer to design and manufacture them as well."
"I agree completely. Mr. Ericsson is an asset to our country—and most certainly will lead us to success in this war. Are you pleased with the ship you command, Captain? This is also his design."
"Not pleased—ecstatic, if you will permit me to use a word with many connotations. I believe that Atlas is the most powerful ship that I have ever commanded. With twin engines and twin screws, she is in a class by herself. And like her namesake, she cannot quite carry the world on her shoulders—but she comes mighty close to it."
The Thames curved in great loops as they made their way upriver. As they came into the Dartford reach, there was the flash of guns from the Mississippi ahead of them.
"That will be the arsenal at Woolwich," Sherman said. "They have some batteries facing the river there, but nothing much to speak of. Tilbury Fort is the major defense of the Thames, and no hostile fleet was ever expected to get by her armaments or reduce her by siege."
"Perhaps that was true of yesterday's wars," Curtin said. "But not today's."
Mississippi was already at the next bend in the river when they passed Woolwich. A few battered and burning gun emplacements on the shore were all that remained of her defenses.
The Thames here made a great swing around the Isle of Dogs, and when the river straightened again all of the commercial heart of London opened out before them. There were ships tied up at the docks on both shores, merchantmen from every corner of the empire. Fresh fruit was being unloaded at Limehouse—whence it got its name. Behind Atlas the line of black ships followed steadily—an invasion force that was piercing straight into the heart of London.
More firing sounded ahead as the American ironclad began trading fire with the batteries of the Tower of London. But here, as in Woolwich, the defenses were not substantial at all. One of the towers of the famous castle crumbled under the ship's fire.
One by one Mississippi's guns grew silent, their work done, as the shore defenses were battered into destruction. Her funnels were riddled with holes, her boats shot away, but other than that, the ironclad appeared unharmed. Smoke rolled up from her funnels as she gained way, moving ponderously toward the riverbank, letting Atlas proceed up the main channel.
The river was clear ahead. Sherman recognized it from the many photographs and maps that he had pored over. On the right was the road along the Embankment, with fine buildings behind it. Beyond the buildings were the Gothic towers of the Houses of Parliament, the main tower with its immense clock face visible far downriver. The hands pointed to noon. Sherman stepped out onto the wing and could hear the deep tolling of Big Ben sounding the hour. It was the beginning of the afternoon of the British Empire.
Atlas's engines were silent as she drifted toward the Embankment, slower and slower. There were hansom cabs and drays on the road there, private carriages and pedestrians. They were fleeing now as the hulking black ship grated against the granite river wall.
Even before she touched, sailors had leaped over the lessening gap, seized the cables passed down to them, and made them fast to the stone bollards of the waterfront. The sudden rattle of rifle fire sounded; two of the sailors twisted and dropped. Bullets clanged against the metal of the bridge, shooting out one of the windows. A line of red-coated soldiers had advanced from Parliament Square. The front rank stopped to fire—just as the bow battery of Atlas fired a canister shell. Holes opened suddenly in the advancing ranks of redcoats. Then a dark shadow passed over Atlas as Mississippi slid by, her guns opening fire as soon as they could bear.
Captain Curtin was out on the wing of the bridge, ignoring the fire from the shore, issuing commands. The moment his ship was securely moored, he ordered the upper ramp to be extended. The outer door swung slowly aside and there was a mighty clanking as the steam pistons pushed the tons of metal out and down. The information that had been passed on by the Russian agents proved to be correct. At this time of day, on this date, at this particular place, where the tidal river rose and fell by a dozen feet, the ramp was exactly two feet above the granite of the river wall. It clanked down into place; metal screeched as the relentless pistons pushed the ramp forward into position.
Inside Atlas, on the upper deck, the Gatling carriers were lined up in even rows that stretched from bow to stern. As soon as the great ship had entered the Thames, the tank crews began removing the shackles and turnbuckles that had secured them in place during the sea crossing. Kerosene lamps on the bulkheads provided barely enough light to accomplish this task.
Sergeant Corbett, driver of the lead machine, cursed as he barked his knuckles on the last recalcitrant shackle, pulled it free of the eye inset in the deck, and hurled it aside. As he did this, green electric lights in the ceiling came on, controlled from the ship's bridge.
"Start your engines!" he bellowed. Drivers and gunners, down the length of the columns, jumped to the task. Private Hoobler, Corbett's gunner, ran to the front of their machine and seized the starting handle. "Battery switch off!" he called out.
"Switched off!" Corbett shouted back.
Hoobler braced himself and turned the handle the required four times, grunting with the effort of pumping oil into the engine's bearings and fuel into its cylinders; gunners were selected for their strength of arm as well as their accuracy of fire.
"Battery switch on," he gasped.
"On!" the sergeant shouted back and thrust closed the small bayonet switch on the control panel. He had to raise his voice above the din of the many barking, hammering Carnot-cycle engines that were bursting into life. Hoobler gave a mighty swing of the handle, but instead of starting, the engine backfired. He cried out in pain as the starting handle kicked back in
reverse and broke his arm.
At this same moment the bow door opened and the blaze of sunlight revealed him sitting on the deck nursing his wounded arm. Cursing even more vociferously, Sergeant Corbett jumped down and bent over the wounded man; the crooked angle of his lower arm was vivid evidence of what had happened.
The tank deck was now an inferno of hammering exhausts and clouds of reeking fumes. As the landing ramp went down, soldiers rushed forward from the machines to the rear, shouldered the sergeant and his wounded gunner aside, pushed their stalled vehicle aside as well. A moment later the second Gatling carrier rumbled past them and forward onto the ramp, leading the others into battle. Its spiked wheels dug into the wooden planks of the ramp as it gathered speed. Coughing in the reeking fumes, Corbett tore Hoobler's jacket open and thrust the man's broken arm into it for support; the soldier gagged with pain. Behind them the carriers rumbled forward to the attack while Corbett pulled open the access door to the deck and half dragged, half carried, the wounded soldier out into the sunshine. Once he had settled the man against a bulkhead, he turned and shouted.
"I need a gunner!"
His words were drowned out by the roar of a cannon firing close by. He ran toward it, dodged the discarded shell casing that rolled toward him. Called out again just as the gun's breech was slammed shut and the gun bellowed again. One of the two ammunition carriers shouted back.
"I shot one of them Gatlings in training!"
The gun captain seized the firing lanyard. "I can spare one man!" he called back, then fired the cannon again. Sergeant Corbett headed back on the run, with the gunner right behind him. "Get aboard," he ordered. Checked the bayonet switch and, with a single mighty heave, turned over the engine. It started at once, roared and rattled as he jumped into his seat. He looked over his shoulder at the line of vehicles rumbling by. The top deck was now clear of vehicles. Before the carriers from the lower deck could come off the ramp from below, Corbett sped up the engine, eased power to the wheels, and jerked forward. Into the daylight and down the landing ramp he drove into combat.
The bark of his engine joined the roar of the others, echoed out from the interior of the cavernous ship. A steady stream of tanks, the Gatling carriers, rolled out and down onto the riverbank. Followed by more—and yet still more machines. While fore and aft the companionways had been dropped and a tide of blue uniforms flowed down from the ship and onto the English soil.
"Fire!" Corbett shouted as they clattered off the ramp onto the cobbles. His new gunner bent to his sights and cranked the handle of his gun. Bullets streamed out as he swept the gun along the line of red-uniformed soldiers.
The defending troops were mowed down like a field of grain by the rapid-firing Gatling guns. Some of the defenders fired back, but their bullets merely clanged off the armored front shields of the carriers.
On the bridge of the Atlas, high above, General Sherman looked down at the surging battle. The enemy line appeared to be broken, the defenders dead or fleeing the blue-clad troops now moving past the slower gun carriers.
"Cavalry!" someone shouted, and Sherman looked up to see the mounted soldiers pouring out of the streets that led to Whitehall and Horse Guards Parade. Brigadier Somerville had done an exemplary job in alerting the defenses. The American soldiers turned to face this new threat on their flank—but the Gatling carriers surged past them. Their exhausts roaring loudly, pumping out clouds of acrid smoke, they surged forward toward the cavalry. Now, with swords raised, helmets and cuirasses gleaming, the horsemen charged at the gallop.
And were destroyed. Just as the Light Brigade had been when they had charged the Russian lines in the Crimea. But here were rapid-firing guns, more deadly at close range than any cannon could ever be. Men and horses screamed and died, wiped out, sprawling unmoving across the road that now ran red with blood.
None survived. General Sherman went down from the ship's bridge to join his staff waiting for him on the shore.
HMS Viperous, the pride of the British navy, led the attack. After taking aboard the pilot off Dungeness, she proceeded at a stately five knots into the main channel of the Thames. The other ironclads, in line behind her, followed in her course. Her guns were loaded and ready; she was prepared to take on any Yankee ironclad and give as good as she received. From his station on the bridge wing, the captain was the first to see the waiting enemy as they rounded the last bend in the river before Tilbury Fort.
There were the American war craft, four hulking black ships drawn up in line across the river.
"Fire when your guns bear," he ordered, looking at the enemy through his glasses. He had never seen ships like this before. Armor was all that he could see—with no sign of gun ports at all. There was a mighty roar as the forward gun turret fired; the ship's fabric shook beneath his feet.
Good shooting. He could see the shells explode against the armor of the ship in the center of the line. The smoke cleared, he could see no signs of damage—then a cloud of smoke blossomed up from behind the enemy's armor. He had a quick glimpse of an immense shell climbing in a high arc, seemingly suspended in space before it dropped. An enormous fountain of water sprang up beside the port bow, drenching the foredeck.
Even before the first shell struck, a second was on its way. This struck the Viperous amidships, and the tremendous explosion almost blew the mighty ship in two.
Anchored and ready, the mortar batteries were as deadly against the slow-moving enemy as they had been against the fortress on land. Within a minute the mortally wounded iron ship had settled to the riverbed, with shells sending up massive waterspouts around the rest of the attacking fleet as they withdrew out of range.
Sherman's rear defenses were secured. He need fear no attacks from the river as long as the floating batteries were in place.
BUCKINGHAM PALACE ATTACKED
More and still more of the Gatling-gun carriers emerged from Atlas and rumbled down the ramp. These had been stowed deep in the ship's hold and had climbed to the disembarking level using a series of interior ramps between decks.
Nor was Atlas now the only ship tied up at the embankment. While the ironclads stayed on station in midriver, the transports at the river wall had sent their soldiers charging ashore. Regiments of riflemen were forming up even as the first cannon were being lowered to the Embankment. The horse handlers led their mounts, trotting up to Sherman's staff; he felt better after swinging up into the saddle.
"We've pushed units up these streets toward Whitehall," an aide said, pointing out the positions on his map. "Our men will be taking defensive positions in the buildings on both sides. There'll be no more surprise attacks by cavalry from that direction."
Sherman nodded approval, touched the map. "These troops in Parliament Square must be neutralized. Then the Gatlings can take out these defensive positions in the buildings there."
"We're taking fire from Westminster Abbey," an officer reported.
"Return it," Sherman said coldly. "If that is their choice, I say that our men's lives come before an ancient monument. I want all the defensive positions reduced before we advance to the Mall. It will be a two-pronged attack, there and down this road. Is it really called Birdcage Walk?"
"It is, sir."
"All right. The staff will join the column there—let the attacking units know. Report to me when you are ready."
The sound of cannon, the tearing violence of gunfire, could easily be heard at Buckingham Palace. From the other side of St. James's Park, above the trees, clouds of smoke roiled skyward. Queen Victoria stood white-faced on the balcony, shaking her head in disbelief. This was not happening, could not be happening. Below her there was the clatter of hooves and the scrape of wheels on the cobbles of the courtyard. She was aware of her ladies-in-waiting calling to her, pleading, but she did not move. Even when one of them was bold enough to touch her sleeve.
A man's voice sounded from the door behind her, silencing the shrill voices.
"Come now, Your Majesty. The carriage
s are here."
The Duke of Cambridge had an urgency in his voice. Victoria's first cousin, he was familiar enough to take her by the arm. "The children have gone ahead. We must go after them."
The children! Mention of them cleared her head and filled her with a certain urgency. She turned from the window and let the Duke lead her from the room. He went on ahead, leaving her ladies to see to her.
He had a lot to do and not much time to do it in. When his servant had shaken him awake that morning, his head was still fogged with fatigue and he could make little of what was happening at first. Warships? The Thames? When he had hurried to his office, Brigadier Somerville made it all too clear.
"The attacks in the Midlands—even capturing Plymouth—that was all a ruse. And it succeeded. They are striking up the Thames, and London is their target."
"Tilbury. The fort there will stop them."
"I sincerely hope so, but we cannot rely on hope. So far everything about this invasion has gone exactly as they have planned. I fear they must have some strategy how they will attack the fort. London must be defended, and I have made every effort to see that is done. The household troops have been alerted and I have sent for reinforcements. Now we must see about saving the government—and the Queen. You must convince her that for her own safety, she must leave."
"Leave? Go where?"
The Duke was being even thicker than usual this morning; Somerville fought to keep the anger from his voice. "Windsor Castle for now. The Prime Minister and his cabinet can join her there. Immediate danger will be averted and further plans can be made once she is safe. She will listen to you. You must convince her that this is the proper course of action. The forces attacking us are overwhelming. If she is seized in Buckingham Palace, why then, this war is over before it has even properly begun."
"Yes, of course." The Duke rubbed his jaw, his fingers scraping over the unshaven bristles. "But the defense of the city?"
