I have decided to start with the Set 1 Historical “O -Tag” December 16th Scenarios. The first of which is the northern sector, Preiss' Push. I am quite experienced with this part of the Bulge, as its the same terrain as one of my favourite scenarios from the Ride of the Valkyries pack, Elsenborn Ridge. In the Knock on all Doors pack however, the map is extended a fair way south and a bit to the west. Instead of having the 3 days and 18 hours of the Elsenborn Ridge scenario, we only have 2 days, 11 hours and 31 minutes to achieve almost the same thing! The emphasis in this scenario is obviously on exiting your force to achieve further objectives to the west and encircling manoeuvres to the south in the best way you see fit, where as in the Elsenborn Ridge scenario you were forced onto historical routes by the need to capture the numerous set objectives. The number of objectives is less than the Elsenborn Ridge scenario, giving you more choice over the route you decide to take to get to the exit objectives. What hasn't been mentioned, but has been hinted at by the location of the objectives, is the need to have a substantial blocking force on the northern flank of the map. As can be seen by the situation map, this scenario takes place on the northern shoulder of the offensive and strong Allied reinforcements can be expected to enter from this side, including the whole of the 2d Inf Division that have to pull back through Krinkelt and Rocherath, as its the only road out from their offensive operations in the Wahlerscheid area, where they are attempting to secure the Roer river dams.
