Gaius Visits the Sea Wall In New Carthage:

Gaius approached Tanit in the shadow of the sea wall in New Carthage. But he had to remind himself that he could not make himself known to her. That would spoil everything. The maps would become useless. The Carthaginians would be alerted, and all his plans and perhaps Cato’s too would come to naught.

He forced himself to remain at least ten paces behind the girl. When she stopped, he stopped and kept to the shadows. When she turned around, he stepped quickly into the darkest part of the shadows. When she speeded up, he sped up. When she hesitated, he hesitated. When she ducked behind a building, he followed.

She kept on looking towards the sea wall as if she were expecting something. Tanit hesitated and seemed to be waiting. So Gaius waited too.

Suddenly a contingent of soldiers in formal costume marched out of the town of New Carthage towards the sea wall in formation. They marched one direction behind the sea wall parallel to it and then marched back again. A similarly dressed contingent of soldiers marched out of the sea wall itself and joined them. Then they both marched in formation behind the wall. The soldiers stopped and saluted each other in what looked like a changing of the guard ceremony.

Only then did the group of soldiers who had been inside the wall march back towards the town and leave the new group of soldiers to take possession of the wall. They did that in short order and shut the door to the inner wall which must be at least twenty feet wide if it was a foot.

Only then did Tanit start towards them. So Gaius followed at what he judged to be a safe, discreet distance. She approached the door that had just slammed shut with a giant bang and knocked.
One of the soldiers answered the door and flung it wide open. As soon as the soldier saw her, he bowed low and said, “Princess!” Apparently she was recognized by the soldiers there as the Princess of Carthage, daughter of Hasdrubal. Perhaps they even knew her mission or had heard about it. The guard seemed to be expecting her.

She withdrew a sheaf of papers from her robe and waved it in front of the soldier. “Take these maps and hide them in a chamber within the wall. On your life don’t tell anybody that they are hidden there. The very existence of Carthage and perhaps of your city too is dependent upon it.”
The soldier motioned with his arm for her to follow him inside. Gaius wished that he could follow, too. They were obviously his maps, the ones he had drawn in person in Carthage when he had visited with Cato. He even recognized them. They were just what he had come looking for. It would be worth a lot to see exactly where they would put them.

But the door slammed behind them. When Gaius reached it, he could not open it. He put his ear to the door. Because of the massive stone ramparts and walls he could hear nothing.

He had to wait on the other side of the street hidden behind a statue to the god Baal complete with horns on his head. Eventually they appeared at the door again and Tanit hidden within her capacious robes took her leave of the soldiers and the seawall.

Gaius remained behind watching and waiting for his opportunity. It did not make any sense to follow Tanit now. She no longer had the maps in her possession. So he bided his time until the soldiers within the sea wall to appear once more. In about three more hours they performed the same feat in the area behind the sea wall. They marched back and forth and once again changed the guard. He saw the guard go off duty who was the one Tanit had been speaking to.

Gaius wondered if that particular guard had passed on the knowledge about the maps to his successors. He realized he would have to return here tomorrow at first light. Then the guards would change for the first time that day. Then Gaius Antonius would have to join them.
