On December 2, 915, the 100,000-strong Second Guards Cavalry Army Group of Prosen majestically crossed the ice-bound Valdai Hills River.
The task of the Army Group was to disrupt Prosen's transportation lines, creating the illusion of encircling the Prosen forces under General Sheeplin, who were in charge of breaking the siege.
Whether the task of creating an illusion was successful or not, this cavalry force of 100,000 could inflict severe damage on Prosen's supply lines.
If General Sheeplin did not retreat swiftly, his troops might have had to cross the frozen Ante Prairie on foot.
This was hardly better than being surrounded; it was unknown how many would freeze to death on the prairies at minus forty degrees Celsius.

At the headquarters of Sheeplin's Army Group, General Sheeplin looked at the reports gathered so far with furrowed brows.
Chief of Staff: "I would bet my military instincts that this is a deception operation, probably involving only cavalry troops."
