There. Took longer than I hoped, but it's up at least.
The general situation as I figured it was that the Wallers were sent to relieve and recall O'Reik's Rounders from their sweep of the ruins out in Westkirk but ran into some trouble with a pair of more advanced monsters ("Horrors") that were backing up the local shambler masses. They barricaded themselves in an old church and have been holed up there waiting to make their move for three days now.
My thought was to have Harker and a few of his men would stay behind and cause a distraction while the rest of the unit made for the ruins with the injured in tow. They would meet up with the party proper, who would then
head back to base camp safely and successfully head out to rescue the Lt. and crew.
Feel free to correct/change any bit of that,
@Vietmyke, I'll adjust my post properly.
