This is quoted from this characters memoire in a thread, not the entire history.

His father was still outrageous he had run from home to join the military in Minas Tirith when the call for aid in the latest hour came. He still remembered the recruiter saying he could do nothing with some youngling that thought he could fight. He surprised the man greatly (and himself,too as a matter of fact) when he showed great skill with the bow. He was even so good, he might have joined the rangers, the problem being he was not from Ithilien. So he was placed in an archer company defending the great gate of Minas Tirith.
He was eager for battle at that time, but he never expected that battle would be so horrible. when the huge mass of orcs and evil men appeared his 1st thought was to run away. One of the veterans, rewarded with the rare Numenorean bows, the best Men-made bows ever, from the time of the last alliance, gave him a morale boost by his comforting words, not that there was much else choice then to stand and fight. Hours after the assault, driven back to the 4th gate, he had shot all his arrows lost his bow and cut his knife blunt, surprisingly how well you fight, when the wager is your life. All he had left was the Numenorean bow of the veteran, who was killed when he protected Arkaniel pulling back to the third gate. So many soldiers had fallen already, the remainng few were on the edge of collapsing and the stream of assaulting orcs didn’t even seem to be thinned…. then the Horns blew. after that he went unconsciousness from the block of wood that fall on his had when a troll kicked the 4th gate in….
He also marched to the Black Gate, there the battle was even fiercer, for now they fought for their lives, their King and the world. he was wounded severly, but then the eagles came and at the same time, all the orcs and nazgul fled, and then it went dark…days later he woke with a bandage around his shoulder.After the coronation, he was awarded with the Numenorean bow and was promoted to Captain. He served for some years, clearing gondor and the Brown lands from the ocs that had fled Mordor after Sauron’s destruction. 2 months ago he resigned, willing to return to his father. His father however chased him away in anger for him running away. Arkaniel was no longer heir of his father, so he decided to make a journey throughout Middle-earth, looking for adventure or an occupation of any other sort.
