I'll try to update with a detailed summary later. For the time being it probably is enough to say that the Spanish got annihilated. Only two Spanish units remained on the map at the scenario end. limited number of entrenchments and massive Soviet artillery allowed the Soviets to breakthrough the lines. They then proceeded to mop up the Spanish an entrenchment at a time using a combination of assaults, artillery, and armour. Nasty.

Fun scenario but probably impossible for the Spanish to win results in a 3/5
