pointed to the foot-holes. âYes, and thatâs how he got away.â He climbed up the vertical bank and peered into the bush; there was a narrow path cut through it that went on for thirty paces down the hill. He crawled down its length and came out into a dell in the hillside, deep enough to obscure him from both the walls above and the auxiliary cohort on station at the base of the hill.
âHe could have got to here unseen,â Magnus said, peering over the edge and down to the troops at the bottom, âbut the rest of the way down is open ground; our lads are bound to have seen anyone coming out of here.â
âLetâs go and ask them.â
Vespasian and Magnus jogged over to the auxiliaries; their prefect strode forward to meet them. âThe fort is ours, legate?â
âIt is, but weâre missing one vital component, Galeo. Did anyone come out?â
The prefect looked confused. âJust the man you sent an optio to bring out: the spy.â
âWhat spy? What optio?â
âThe young lad seemed too young to be an optio but it was hard to tell under all the grime on his face.â He pulled a scroll from his belt and proffered it to Vespasian. âBut he had written orders with Plautiusâ seal on, giving him permission to get our agent out of the place before it fell, so he wouldnât get killed in the chaos of the assault.â
Vespasian glanced at the scroll, knowing immediately that it was a forgery. âWhen was this?â
âJust after the attack started.â
âWhere did they go?â
âThey rode off, around the fort heading for our camp.â
âAre you sure that they didnât turn away and ride off?â
âI donât know; I didnât pay them any attention once theyâd gone.â
Vespasianâs fists clenched. He felt like pummelling the man although he knew that it was not his fault; he had been duped. âThis optio, did he give his name?â
âYes, sir; Alienus.â
Vespasian raised his eyes to the sky. âI might have guessed.â
âSo he was from you?â
âNo, prefect, he was not.â
CHAPTER II
âW E PICKED UP their trail, sir; they doubled back and headed west.â Lucius Junius Caesennius Paetus, the young prefect of the Batavian auxiliary cavalry ala, reported in clipped patrician tones, standing to attention on the opposite side of the desk to Vespasian in the praetorium tent. âJudging by the tracks, they were a good two hours ahead of us. After five miles or so they met up with a group of at least thirty horsemen and changed direction to just north of west. By that time the light was fading and we had to turn back.â
âThank you, prefect. Maximus, have you had the legionâs casualty list?â
âIâm just waiting for the second, third and fourth cohortsâ reports; they suffered the most scaling the walls. Iâll bring it to you when itâs complete.â
âHas there been a report of an optio going missing just before the attack?â
Maximus looked surprised. âHow did you know, sir?â
âA guess. Well?â
âThe optio from the sixth century, ninth cohort went missing just before the assault started as the cohort moved into position.â
âThank you, Maximus.â Vespasian looked over to Cogidubnus, seated to the right of him next to Valens. âHow long is it since youâve seen your cousin Alienus?â
âVericaâs grandson? Why?â
âBecause I believe that he was the man masquerading as the optio who got Caratacus through our lines.â
The Britannic King thought for a few moments. âNot since he was a boy, well before he went to Rome, say six or seven years. Why?â
âCould you identify him?â
âI doubt it after all this time; heâd be a man now and I only saw him a few times as a lad.â
âA pity.â Vespasian looked at
