The Alaxxes gulf presented tactical challenges: there was no space to spread out into the void, or to make elaborate manoeuvres. They would be fighting in the largest of the gas tunnels, hemmed in on all sides by the shifting curtains of foaming crimson. The aperture’s diameter at the narrowest point was less than two hundred kilometres – a claustrophobic space to be marshalling a battlegroup in, and one that gave almost no room for proper movement.

Given those constraints, Lord Gunn had opted for the one thing his Legion could always be relied upon to excel at: full-frontal assault, conducted at speed and with full commitment. The core attack from the capital ships would be supported by two wings of strike cruisers, each one aiming to power ahead on either flank to hem in the lead Alpha Legion vessels and keep their lateral gun-hulls busy. As soon as battle was joined, Gunn would give the order for massed boarding torpedoes and gunship assaults. The earlier encounter in the deep void had driven home the lesson that the Wolves’ only real advantage lay in hand-to-hand combat, despite the self-evident risks of losing warriors to a more numerous enemy. Lord Gunn’s aim was, so he told his brothers, to ‘ram our blades into their throats, twisting them so deep their eyes will burst’.

No one disagreed. The councils were concluded, swords were sharpened, armour was sanctified with runic wards and battle-rites were completed. Being hunted didn’t suit the Wolves, and the chance to turn the tables sat well with the Legion’s bruised soul.

Late on the second day, as the chronometer had it, the fleet was put on high alert. The trajectories had already been calculated, responding to expected Alpha Legion movements. The pursuing fleet was allowed to close in through a gradual slowing of the main plasma thrusters, made to look consistent with steadily leaking containment shells.

Throughout all of this, Russ remained only part-engaged. He spent increasing amounts of time in his own private chambers. Petitions went unanswered. Soon it became apparent that he’d meant what he’d said: this was Lord Gunn’s attack.

As the fleet chronometer clicked into the nominal nocturnal phase, trigger-signals were distributed throughout the Wolves’ rearguard, alerting them to the imminent movement of the battleship-core. The trailing escort vessel Vrek reported augmented real-view sightings of Alpha Legion outriders at a range of nine hundred kilometres, and those readings were fed into the prepared attack-pattern cogitators.

Six minutes later, the order for full-about was given and the bulk of the rearguard executed a lazy turn. The slowness of the manoeuvre served two purposes: to allow time for the lumbering battleships to bring their forward lances to bear, and to delay alerting the enemy that a major reconfiguration was underway until the last moment.
