Southern/2nd Army sector:
The Russian 4th Cavalry Division with 4 cavalry battalions forms the right flank of 2nd Army.
I informed my opponent about the 4 Redoubts in the area. The one at Niedersee makes an advance by 4th Cavalry Division to that area (on the bottom left edge of the previous screenshot showing II Army Corps) pointless as cavalry units have no means to deal with hard targets due to a HA value of 0.
VI Army Corps is advancing through the border fortress of Lomza. In the lead is 16th Infantry Division with 16 battalions, 4 of which start Fixed in fortress Osowiec (about 50 kilometres to the north-east) until the 23rd. Behind them is 4th Infantry Division which starts and stays understrength with 12 battalions. In front of 16h ID is a battalion from 4th Cavalry Division.
XIII Army Corps with 36th Infantry Divisions with 16 battalions on the right and 1st Infantry Division with 16 battalions on the left is advancing through wooded marshes in the center of the 2nd Army sector.
XV Army Corps is advancing along good roads north of Przasnysz with 6th Infantry Division, 16 battalions, on the right and 8th Infantry Division, 16 battalions, on the left.
Samsonov and his 2nd Army HQ starts in Ostroleka.
On 2nd Army's left wing, I Army Corps with 22nd Infantry Division, 16 battalions, in the lead and 24th Infantry Division, 16 battalions in the rear is moving towards Mlawa.
The tail end of 2nd Army consists of 2nd Infantry Division, 16 battalions, of XXIII Corps. The 3rd Guard Division was part of this corps, but remained in the rear in the Bialystok-Grodno area. It can arrive later as a strategy option, if 2nd Army commander Samsonov "historically" commits suicide.
There's a substantial cavalry screen in front of the left wing of 2nd Army with 15th Cavalry Division, 4 battalions, on the left and 6th Cavalry Division, 4 battalions on the right. One battalion of the latter is in front of 36th ID in the XIII Corps area.
"Holding" a 80 kilometre long line at the border obstacles is Hauptreserve Graudenz with an Ersatz and Landwehr Brigade: Stellvertretender Infanterie Brigade 69 with 6 Ersatz battalions and gemischte Landwehr Brigade 70 with 5 Landwehr battalions. First order of business will be moving the entire formation to the area between Soldau and Neidenburg.
The only regular German divisions belong to XX Armeekorps. 41. Infanterie Division is positioned behind the Omulew river with 12 infantry battalions. 37. Infanterie Division with 12 infantry battalions is holding a line of obstacles around Ortelsburg.
