Here a picture of the starting situation

Without the river protecting me, my forces are very ill prepared to take on the massive Soviet forces attacking (which consist of plenty of artillery, airforce, infantry and soon also tanks).
The only way I see is to pull together all forces to the airport/supply hex and somehow pray they don't get overrun immediately. At least 3 auxiliary units have to survive the mission. Sadly it will take me several turns just to reach the position, deploying from the southern border of the map.
Did someone do this scenario and if so, how did weather treat you?
