In the year 2885 of the Third Age, during the reign of Steward Túrin II of Gondor, the Haradrim assailed Southern Ithilien with great strength at the Crossings of Poros where Túrin II and King Folcwine of Rohan mustered their armies for defense against the Southern storm. The Haradrim, when they were ready, launched the assault,
The battle waxed furiously on the vale of Poros. The enemy cavalry rode back to the main host, as the Southrons began to make ordered ranks to hold a defensive position at a mere hundred yards from the Fords, while they bought time for the Mumakil and the army of Khand, who were crossing the fords. For the Mumakil, this would be slow, because even though these creatures of the desert thrilled at the sight of water, they were afraid of crossing large bodies of water, including a river, and the army of Khand was probably behind them.
Meanwhile, the armies of Gondor marched ahead of the Rohirrim. The spears and swords of Gondor drove through the enemy, who in their confusion had placed the pike-men at the front, expecting that the Rohirrim would charge first.The pike-men were annihilated because they were ineffective against other infantry. The soldiers of Gondor smashed through the ranks of the pike-men and fought long and ferociously with the legions of Haradrim. After hours of knife-work, the remains of the Haradrim forces fled back South, crushed by the valor of Gondor and Rohan.
Overall, this battle was somewhat a Phyrric victory for Rohan and Gondor alike, partly due to the deaths of Folcwine's sons, Fastred and Folcred.
