+5 Hours Terran Sidereal – LZ Dorn
With each passing hour the Traitors begin to mount a more significant counter offensive against the Loyalists, including committing more armoured units. In particular the Raven Guard to the North of the bridge face a grind down until they can be relieved.

+8 Hours Terran Sidereal – Lethean Highway
Loyalist armour headed up by the 1212th Piscaian Cohort punches through a key Traitor checkpoint. Sub-lieutenant Etin breaks the deadlock with a flanking move through Hab 75A-b. The Loyalists are now within sight and artillery range of the south of the bridge.
+8.05 Hours Terran Sidereal
Intercepted civilian vox traffic states Perturbo is in Primus Aeterna. Expeditionary Fleet Intelligence Corps is awaiting confirmation.

+8.5 Hours Terran Sidereal
Bombers from the 7401st Bomber Wing begin runs on the hive itself, but with intra-atmospheric cannons still in Traitor hands, they suffer heavy losses to inflict as yet limited damage on the hive walls. Runs are ordered to continue.
+13 Hours Terran Sidereal – LZ Dorn

The heaviest assault on the Raven Guard position to date starts. Tactical squad Vorys confirms sight of Perturabo leading the assault. SHLFX reroutes additional assets to take on a primarch level threat, including a fire raptor wing.

However entrenched Iron Havocs shred the air support before it can fully engage, earning them a dreadful nickname. The venerable Raven Guard Leviathan causes Perturabo to withdraw in a barrage of phosphex and grav. With his primarch retreating, Draxion seeks to rally the Iron Warriors assault but to no avail. The Raven Guard continue to hold the suburbs around the northern end of the bridge.

+1 Day Terran Sidereal – Bridge South
Loyalists mount Operation Fruhaven, an armoured assault with the goal of conquering the hab blocks near the southern edge of the bridge. The force is primarily made up of Iron Hands and Raven Guard, though General Verox deploys as an observer.

Against them stands a formidable force of Emperor’s Children and Iron Warriors. It is hoped that the two Loyalist super heavies Beathach Mor and Shadow Born will provide enough firepower to carry the day.

+1 Day, 6 Hours Terran Sidereal – Bridge South
The force makes initial headway only to be turned back when a monstrous serpent appears and butchers the Raven Guard infantry [Post script: EFIC later matched this with other confirmed accounts of Fulgrim described by some accounts as “transformed”]. Additionally Perturabo, now supported by his Iron Circle, drives back Iron Hands immortals, who give their life to try to hold ground but to no avail.

Emperor’s Children assault troops descend on the Iron Hands gunline rapidly, tying them up and silencing their guns. By nightfall, with the Loyalist position untenable, Verox orders a Loyalist withdrawal to their previous positions.
+1 Day, 13 Hours Terran Sidereal
The 316th Company of the Ultramarines is given the signal by Praetor Tiamat, Astartes Liaison to the SHLFX to withdraw from their other offenses and consolidate by LZ Russ.
+1 Day, 18 Hours Terran Sidereal
En Khosi, Chief Intelligence Officer radios from the Northern pole stating that he has secured Burgundy level intelligence concerning Primus Aeterna and is flying back to SHLFX to debrief in person.
+2 Days, Terran Sidereal – Status
Loyalists continue to hold the northern side of the bridge while the southern still belongs to the Traitors. The intra-atmospheric cannons remain Traitor-held. Loyalist Mechanicum have begun distributing reserves from Refinery Kleomon. The Loyalist assault towards Primus Aeterna continues, but with slower progress than anticipated. The Loyalists make fair progress against all other hive cities.
