Final answer:
Sal wants to send Nic into the cave thought to contain Julius Caesar's remains to block the passage and prevent an army from crossing the Pyrenees.
Step-by-step explanation:
Sal wants to send Nic into the cave thought to contain Julius Caesar's remains because he believes an army with a commander will come to fight him. Sal wants Julius to block the passage of the Pyrenees and prevent the army from crossing. However, this plan fails when Julius is killed by Calpurnius and his soldiers abandon the Pyrenees. Sal then retreats to New Carthage and later tries to attack Annius with a fleet, but his ships are wrecked by a storm. So, Sal wants to send Nic into the cave to prevent reinforcements from reaching him.
In a strategic move, Sal devises a plan to send Nic into the cave, believed to house Julius Caesar's remains, with the mission to block the passage and thwart any potential army attempting to cross the Pyrenees. This calculated decision underscores the gravity of the situation, emphasizing Sal's reliance on Nic's skills and courage.
The ancient cave, laden with historical significance, becomes a battleground for contemporary strategy. Sal's directive adds a layer of tension to the narrative, blending historical echoes with the urgency of a modern military maneuver, creating a riveting storyline as characters navigate the intersection of ancient relics and contemporary conflicts.
