(May 20th 2789 A.D.) Gallipor Invades the world on the otherside of the Gates, later discovered to be known as Cascadium.

Initial efforts lead to the capture of some nine to fifteen thousand of the other world's population whom are taken to the otherside and sent to various interested parties, most destined for upper level indentured servitude due to knowledge of reading, writing, and more modern ways of doing things.

The technological loot from these initial opening moves is sent back to the homeland (after being picked over by the officers involved).

Most initial attempts by the security forces of Cascadium are at best stop gaps and delaying actions leading some adhoc units or even small units being traded to buy settlements time to evacuate as formerly dormant units stand up and deploy.

Day Seven - Gali forces suffer their first major setback in the campaign after leading elements of their main force encounter a Cascadium Defense Force (CSF) tank battalion with company sized infantry support and air power. Roughly two battalions of their armor are destroyed along with a regiment of infantry. As a result their high command orders a hold and calls up reinforcements from the otherside of the gate.

Day Eight - CSF forces begin a general counter attack at midnight with various light mechanized units deployed from the air on the Gali force's flanks and a main armored and mechanized force driving head on into the invader's established positions. Despite numbers and prepared positions the Gali invasion force and its various auxiliary are badly mauled by a now prepared and technologically superior enemy. By dawn the Gali army has begun to fall back from whatever remains of its forward positions, some rear units even beginning to rout back toward the gate.

Day Nine - CSF forces are in full pursuit of retreating Gali invasion forces with stragglers surrendering on mass, slowing the advance. Some unit commanders, witnesses of the conduct of this force toward Cascadium civilians simply gun them down in place and move on. Others process, disarm, and leave behind small guard forces in order to continue the advance. Additionally CSF forces are bolstered by the arrival of United American Starzone Marines whom are dropped into predesignated DZs already secured by CSF forces, however units are kept on orbit for use as spot reinforcements and for a planned shock and awe operation against the source of the invasion.

Day Ten - CSF forces continue a general offensive with one main force and two 'wing' forces pressing in the Gali perimeter from three sides, ever shrinking their previously easily acquired new territory. However this has the side effect of focusing their remaining forces into a smaller area and as a result resistance ramps up. The Gali general, bolstered by reinforcements from his world and still believing the effort can be won commits to a major armored thrust in the gaps between the wings and the main CSF force, attempting to flank and engulf. A mass employment of air and space assets by both the CSF and UASM and vicious spoiling attacks from the forward CSF units halt, cut off, and destroy this final offensive. To prevent the hostile army from slipping away with any more of the captured civilian population two heavy battalions of marines are dropped directly onto their primary strongpoints around the 'Gate'. With mechanized assets and power armor the forces around them rapidly find a powerful and technologically advanced threat in their rear.

Dawn, Day Eleven - While scattered resistance continues the surviving highest ranking Gali officer makes contact via radio and offers terms, he is rebuffed with a unconditional surrender demand and accepts it several hours later. Three days beyond this point the area is completely pacified and all hostile troops are disarmed and moved into mass holding areas under guard. One heavy marine battalion however has pushed through the object and into the world beyond, preventing its deactivation and establishing a foothold in the world of Eideon.

(Pre-June 15th 2789 A.D.) CSF and UASM forces have established a kilometer wide perimeter and held the gate structure on the otherside for the better part of half a month. After one major attempt to retake the structure and the surrounding ruins (noted by the first troops through) it has been quiet aside from the occasional incursion by small hostile units. Unbeknownst to them they've set off a mass uprising in the occupied territory the structure currently sits on. However high and low level observation via VTOL Drones has begun and the plan to push through into this other world has more or less been completed with the Cascadium side becoming a mass staging area.

(June 15th - Operation Dusk Chariot) Along with organic attachments and pre-scheduled support assets to further strengthen the existing base perimeter eight mechanized battalions are deployed through the gate and staged. Their task is taking eight predesignated areas of interest that are between ten and twelve kilometers from what was now designated as 'Site Threshold' by CSF command. These sites include high points, supply route critical areas such as crossroads and settlement sites that control the first, and a high traffic river bridge. These units began to roll at roughly one AM local time on June 16th.

(Storming Dunafoldvar - The Bridge Over the River Doovn) Roughly twenty kilometers to the south of the Threshold Site, the settlement of Dunafoldvar or on the maps of the CSF and UASM units, Objective Dusk 4. Estimated to be a small city with a population of thirty to forty thousand, it controlled a crossroads that brought five major overland routes together to cross the sole bridge capable of handling heavy traffic for nearly a hundred kilometers including a smaller rail bridge immediately adjacent. As a result, despite its somewhat greater distance versus other Dusk objectives it was selected as one of the first sites to be taken. Mostly on the want of CSF command to interrupt east to west supply movements for Gali forces to the west.

Unlike the other battalions, due to both the increased distance as well as the more complex nature of their target, the 2nd of the 1st CSF Mech Brigade was reinforced with a few additional motorized companies from the 9th Infantry Regiment and a company of tanks from the 2nd Composite Armored Brigade. This gaggle of armored vehicles and trucks followed across the landscape by a detached element of logistical vehicles to stage them. 'The Gaggle' as the commanding Colonel had taken to calling it would arrive by dusk on the outskirts of Objective Dusk 4 to the strange site of its garrison, or rather what was left of it, trying to fight its way back in. Most cut and ran toward the north and south upon sighting what they could only guess where the armored vehicles of the other worlders, the rumors of them having reached their ears by retreating and routed units coming from the mystical complex to the north.

Roughly two companies worth of infantry and some scattered armored vehicles stand and fight from prepared positions between the on rushing CSF forces and the outskirts of the small city. While the skirmish is short both units, seeing either surrender to an unknown or what is at their back fight to the last man.
