After a hard march up the Anduin, the detachment led by Boromir finally reached the place where they intended to launch the assault on Cair Andros. Arriving at dusk, Boromir allowed his men to rest, concealed in a wooded area along the rivers western bank. His force consisted of his own retinue of Citadel Guard, 2 companies of Gondor Infantry and 3 companies of Pelagir marines. It was known that the band of rebels in the fortress was at least 500 in number and although the men of gondor outnumbered their foe, some of the men had expressed their doubts that such a small force could successfully capture the fortress and that an attacker would require thousands of men to take the former mighty fortress of Gondor. Boromir spoke to his men as they sat at their campfires, telling his men that the rebels were known to have filled the citadel with wine and booty, the fruits of their years of banditry along the Anduin. Boromir promised his men that those who followed him into fortress would have a share in this prize.
As the sun rose Boromir dispatched men to cut down some trees to construct barges and siege equipment. After a hard day of work a ram and the equipment needed to ferry it across the Anduin had been completed. The Pelagir marines had spent the day hollowing out trees to use as canoes and as the sun began to fall, Boromir rewarded his tired men with a cask of ale to quench their thirst. As darkness fell, the Pelagir Marines prepared themselves to make the assault across the river while the men not required for the initial crossing got what rest they could. At midnight the assault commenced with the Pelagir Marines steathily crossing the river in there makeshift canoes, laying a cable as they went. They reached a part of the shore that was not visible from the fortress and quietly dispatched several rebel sentries, while engineers rigged the cable used to haul the barge that would carry the ram across the river. As the sun began to rise a rebel patrol spotted the men of Gondor and raced back to warn the fortress. The assault party came under sporadic fire from a small force of enemy archers but the rebels were unwilling launch a serious attack, instead waiting atop and behind their high walls for the eventual assault.
When the ram had successfully crossed the river, the assault on the fortress commenced. Boromir lead his men forward to death or glory.
Having successfully crossing the Anduin with the siege equipment, Boromir and his men advance towards the fortress.
Ill disciplined rebels crowd the walls, eager to shoot down the attackers in a hail of arrows. In their rush to man the walls they have left the whole eastern section unguarded.
As it starts to rain, Boromir commands the Pelagir Marines to advance and demonstrate before the walls with the intention of deceiving the defenders.
The defenders open fire on the advancing Marines, who advance within bow shot of the walls before quickly withdrawing out of range as they come under fire. This process is repeated several times to keep the defenders unsure of our intentions.
Meanwhile Boromir leads the other half of his force around to the eastern shore, using the terrain to conceal his move.
Upon reaching the eastern shore, Boromir surveys the defences there.
The defenders have noticed the move and shift their forces to meet the new threat from the east. Due to poor discipline and coordination, no men are left in place on the western wall.
Sensing an opportunity, Boromir sends a runner to the Marine commander, instructing him to assault the western gate with the ram. The Pelagir Marines must get the ram to the gates before the defenders realise their mistake.
They are successful and they begin to batter down the gate.
Boromir's men prepare to assault the east wall with their ladders.
The gate is smashed open and the Marines storm through the breach.
Panicked by the sight of enemies behind them, the rebels abandon the walls and attempt to flee to the citadel.
Boromir's men scale the now abandoned east wall.
As the Marines attack the retreating rebels, Boromir's men rush to hit them from behind.
Unable to escape to the citadel, the rebels are surrounded and cut down. The Marines come under fire from archers on the citadel hill.
Boromir attempts to form his men into a proper battleline before advancing uphill, but with casualties mounting from the enemy archers, Boromir leads his men in a hasty charge uphill to the citadel.
Leading from the front, Boromir throws himself at the enemy. Although possesing the high ground, the rebels are no match for his retinue of elite Citadel Guard.
The Marines form up behind the Infantry and discharge their javelins into the packed enemy ranks...
...and then maneuver to strike the enemy flanks.
The rebels are compressed into a tight ring and are butchered by the men of Gondor. The rebel commander is cut down alongside his men and the battle is won.
The citadel is captured and the men burst through the doors, eager to claim the treasure therein. Prisoners are placed in chains and are sent under guard to Minas Tirith for punishment.
Boromir expresses regret that men must fight one another when they should unite against Saurons growing threat, however a great fortress has been returned to Gondor and Boromir has won a great victory for his father. A messenger arrives, bringing word that another Orc assault on Osgiliath has been repulsed with heavy casualties.
The white tree flies once again over Cair Andros. Now to deal with the trouble in the south.
