A/N: I'm going to MAKE THIS CLEAR. Just like I mention on my bio page about every other fanfiction I done: I DON'T OWN THE PERCY JACKSON AND THE OLYMPIAN SERIES OR IT'S CHARACTERS as the rights goes to Rick Rioran. Also I suggest you guys start paying attention to the Author notes and my warnings that I left on EVERY chapter of EVERY story. Because I KNOW I warn all of you about the first chapter before it started.

Keep in mind it would be hard to be original with Hazel's and Frank's Flashbacks in this story. Sorry if this chapter is too much like the book

Frank's POV Part III

I never felt so sure of anything, which made me nervous. Nothing I ever planned went right. I always manage to break, ruin, burn, sit on, or knock over something important. Yet, somehow, I knew this strategy would work. Because in away, it was sort of like how Percy mention the Attack Plan Macedonia, with Dakota's group attacking up front, Gwendolyn attacking from the west, and us three coming to the east. Just improvised.

Hazel found us a tunnel with no problem. In fact, I had a sneaking suspicion that she didn't just find tunnels. It was though tunnels manufactured themselves to suit her needs. Passages that had been filled years ago suddenly unfilled, changing direction to lead Hazel where she wanted to go. We crept along the light of Percy's glowing sword, Riptide.

Above, we could hear the sounds of the battle—kids shouting, Hannibal the elephant bellowing with glee, scorpion bolts exploding, and water cannons firing. The tunnel shook and dirt rain down on us.

I slipped my hand inside my armor. The piece of wood was still safe and secure in my coat pocket, though one good shot from a scorpion might set my lifeline on fire…

Bad Frank, I chided myself. Fire is the 'F-word.' Don't think about it.

"There's an opening just ahead," Hazel announced. "We'll come up ten feet from the east wall. I'm not sure how I could tell, but I'm certain."

"Might be a Pluto thing," Percy said.

"Maybe," Hazel agreed.

"Could we tunnel straight under the wall?" I asked.

"No," Hazel said. The engineers were smart. They built the walls on old foundation that go down to bedrock."

At that moment I stumbled over something and cursed. Percy brought his sword around for more light and I saw that I tripped over gleaming silver.

I crouched down to inspect it.

"Don't touch it!" Hazel said.

My hand stopped a few inches from the chunk of metal. It looked like a giant Hershey's Kiss, about the size of my fist.

"It's massive," I said. "Silver?"

"Platinum." Hazel sounded scared out of her wits. "It'll go away in a second. Please don't touch it. It's dangerous."

I didn't understand how a lump of metal could be dangerous, but I took Hazel seriously. As we watched the chunk of platinum sank into the ground.

I stared at Hazel. "How did you know?"

In the light of Percy's sword, Hazel looked as ghostly as a Lar.

Another explosion rocked the tunnel.

"Let's figure that out later," Percy said, "The sooner we get this plan done, the better."

Neither Hazel nor I disagreed, but I can't help but noticed that Hazel looked relief when Percy suggest that. We forged ahead.

We popped out of the hole just where Hazel had predicted. In front of us, the fort's east wall loomed. Off to our left, I could see the main line of the Fifth Cohort advancing in turtle formation, shields forming a shell over their heads and sides. They were trying to reach the main gates, but the defenders above pelted them with rocks and flaming bolts from the scorpions, blasting craters around their feet. A water cannon discharge with a jaw rattling THRUM, and a jet of liquid carved a trench in the dirt right in front of the cohorts.

The Third and Fourth Cohorts weren't even advancing. They stood back and laughed, watching their "allies" get beat up. The defenders clustered on the wall above the gates, yelling insults at the tortoise formation as it staggered back and forth. War games had deteriorated into "beat up the Fifth." As if the other Cohorts were sending a message: "just because you got a descent sword fighter doesn't mean you'll win."

My vision went red with anger.

"Let's shake things up." I was about to reach my quiver when Percy grabbed my shoulder. "Hold on a second. I want to try something first."

Percy moved his sword to his left hand, took a deep breath, and snapped his fingers. When he did there was a strong breeze and the guards up above suddenly moved out to other part of the wall, leaving only enough people to manned each Scorpion and Water Cannon. It also eased the attacks on Dakota's group.

"What did you do?" Hazel asked.

"I—uh—sort of used the Mist to convince most of the defenders to help their buddies on the south wall," Percy said.

I blinked. "You can manipulate the Mist? Since when?"

Percy shrugged. "I can't remember, I just sort of knew."

"We can solve the Mist Manipulation later, right now we need to scale the wall," Hazel said.

I nodded. I reached in my quiver and pulled out an arrow heavier than the rest. The iron tip was shaped like the nose cone of a rocket. An ultra-thin gold rope trailed from the fletching. Shooting it accurately up the wall would talk more force and skill than most archers could manage, but I had strong arms and good aim.

Maybe Apollo is watching, I thought hopefully.

"Is that supposed to be a grappling hook?" Percy asked.

"It's called a hydra arrow," I said. "Can you knock out those water cannons."

"With that water pressure? No problem!"

Above the remaining defenders noticed us. "Hey!" he shouted to his remaining buddies. "Check it out! More victims!"

Percy closed his eyes and raised his hand.

Up on the wall, somebody yelled, "Open wide losers!"

KA-BOOM!

The cannon exploded in a starburst of blue, green and white. The remaining defenders screamed as a watery shockwave flatten them against the battlement. Kids toppled over the walls but were snatched by giant eagles and carried to safety. Then the entire eastern wall shuddered as explosion backup through the pipelines. One after another, the water cannons of the battlement exploded. The scorpions' fires were doused. Defenders scattered in confusion or were tossed through the air, giving the rescue eagles quite a workout.

At the main gates, the Fifth Cohorts forgot about their formation. Mystified, they lowered their shields and stared at the chaos.

At that moment I shot my arrow. It streaked upward, carrying its glittering rope. When it reached the top, the metal point fractured into a dozen lines that lashed out and wrapped around anything they could find—parts of the wall, a scorpion, a broken water cannon, even a couple of defending campers, who yelped and found themselves slammed against the battlements as anchor. From the main rope, handholds extended as two-foot intervals, making a ladder."

"Go!" I said.

Percy grinned. "No Frank, you should lead. Show your dad what you can do."

I hesitated. Then I slung my bow on my back and began to climb. I was halfway up before defenders recovered their senses enough to sound the alarm for those at the south wall—probably arguing over a false alarm.

I glanced back at the Fifth Cohorts main group. They were staring at me, dumbfounded.

"Well?" I screamed. "Attack!"

Gwen was the first to unfreeze. She grinned and repeated the order. A cheer went up from the battlefield. Hannibal the elephant trumpeted with happiness, but I couldn't afford to watch. I clambered to the top of the wall, where three defendes trying to hack down my rope ladder.

For once, I'm glad I'm big, clumsy, and clad in metal, because it turned me into a heavy armored bowling ball. I launched myself at the defenders and they toppled like pins. I got to my feet. I took command of the battlements, sweeping my pilium back and forth knocking down defenders. Shot some arrows. Some tried to get under my guard with their swords, but I felt unstoppable.

That's when Percy leaped onto the wall and uncapped his thermos and summoned a water blast out of it, that knocked the defenders away, giving Hazel time to come up and appear at my side with her cavalry sword like she was born for battle

Together we cleared the defenders off the walls as down below Hannibal barreled into the fort, arrows and rocks bouncing harmlessly off his Kevlar armor. The Fifth Cohort charged in behind the elephant, and the battle went hand-to-hand.

I could hear the Third and Fourth Cohort coming to an attack—most likely realizing we're about to take the glory, but it was too late.

"Let's get the banner before they could," I said.

Hazel and Percy nodded and together we moved like a team, as if the three of us had been working together for years. We rushed down the interior steps and into the enemy base.
