As the sun crept over the horizon, B battalion, with the Maus at the very front began to drive down the hill, with A & C already well ahead of them. The tanks of A & C battalions has been instructed to turn their engines off once they reached their destinations. Just as light hit the Maus, all hell broke loose. The Maus fired first, breaking the relative silence with the loud, deafening roar of its 128mm main gun, followed by its 75mm coax gun, then by the twelve simultaneous 75s and 88s, destroying at least ten enemy tanks, including the only KV-2. In just a few heartbeats, around twenty were fired back, but with little effect. Around five seconds later, another volley of fourteen rounds hit them, laying waste to the battlefield and disabling the JS-2. The heavy tanks simply were not affected by them, as they had armor that couldn't be penetrated at this range. The Maus even took over twenty hits to its frontal armor without a scratch. This however, couldn't be said about their armor, which was penetrated with ease.
In an attempt to get closer, the tanks of Chi-Ha-Tan moved to either side of the valley, only to be almost completely annihilated by A & C battalions after taking heavy fire from B. And so, in typical Chi-Ha-Tan fashion, they decided that they may as well charge while they could.
Within minutes of 'charging' only one of Chi-Ha-Tan's tanks remained, leaving only the remaining medium tanks and Anzio's tankettes.
Once the heavy tanks were within 800m of Pravda and Anzio's tanks and tankettes, the order was given to begin firing on them non-stop and not to allow anything to leave the valley. It was at this time that A C squadrons began their attack, their encirclement complete. While the heavy tanks continued their volleys, the light tanks and the Panzer III's were sent to chase down the tankettes if they escaped.
Twenty minutes later, all was quite, and sun had risen, revealing the tank graveyard in the valley. Only two tankettes, one T-34, and the P40 escaped the encirclement.
While the heavy tanks continued on to secure the enemy camp, leaving the Maus, one Tiger II, and the tank destroyers left to guard their own, all remaing medium and light tanks gave chase to the four escaped tanks and tankettes, finally destroying the last remaining tank (Anchovy's P40) two hours later.
