Prelude: Across the Redwake

After a cold night camped in what little cover was available, the refugees from Ailech have awoken in hostile territory close to the Erwach Bridge intending to break through the Goblin patrols to get to Fluchtdorf. The greatest fear is that the Undead will continue their pursuit and catch the fleeing refugees before they can cross the bridge. Meanwhile, word has reached Fluchtdorf and the local Baron, von Zarovich, has sent out a force to help the refugees across the Redwake River.  Belinus mac Gadeon and his Seniirans had headed north to find another crossing fearing that overnight the opposition guarding the bridge may have become overwhelming.
The heroes set out for the bridge but were noticed by a goblin patrol off to their left. Swift action by Bishop Guire's borderers and Greencloak's elves, dealt a critical blow to almost all of the patrol while the rest of the heroes forces pushed on. Critically a force that was suspected to be close to the bridge proved to be a false alarm and Altengard horns could be heard from the other side of the bridge. Hoping against hope the heroes realised that reinforcements had arrived. True enough, Altengard barony forces and some Borderers were marching eastward towards the bridge.
Hopes were quickly dashed though as from the east following the trail the heroes had taken the previous day another force of Undead (this time led by the Wraith, Azalin Ebonhaunter). A large force of infantry appeared hot on the heroes heels, while across the river a wraith scout found the flank of the Altengard reinforcements.
Again the heroes dithered and again the heroes were forced on to the defensive. With goblins ahead of them and skeletons behind things were looking grim and the fighting became more and more intense. After dealing with the wraith the Borderers and their Altengard allies pressed on towards the bridge, intercepting a large body of Goblin infantry along the way. The fighting became tense. A handful of elves and Throrin the berserk engaged the remaining goblins on the eastern side of the river. This patrol  led by Rug Longtooth himself also had an ogre and some Black Moon goblins. The ogre got lucky against Throrin and laid him low which immediately resulted in a panicky attempt to get him clear before he got trampled under the feet of the relentless tide of greenskins. Meanwhile on the eastern ridge the Undead came on without their wraith leader in a slow but purposeful march held up only by the weakened Kronin and some of Guire's light troops. Their fate was to be no less than that of the wounded berserk. Kronin was cruelly stabbed and hacked by the scythes and pole-arms of the vicious undead, while the last of Guire's borderers was left bleeding in the dust. On the western side of the river, the Altengard reinforcements were driving back both the goblin patrol and the force of ogres guarding the bridge. Looking up, the beleaguered heroes realised the path to the bridge was clear and gathering up what injured they could, they made a dash for the bridge and safety. Greencloak's elves and Lord Erkenfried were caught at the lip of the bridge, and the elven archer bravely gave his life to help Erkenfried escape.
Escape had come at a cost though. Kronin was dead, Greencloak's elven band was seriously depleted and only a handful of Guire's borderers still lived. Fluchtdorf lay over the next rise and perhaps Baron von Zarovich could assist with reinforcements...
