The exchange of fire was tremendously quick.
Even as the Eun City's Mothership volley of fire was like a battle orchestra riding on the thunder clouds with their sea crew screaming at each other, giving out the orders to fire from their higher ups. The tremendous series of firing was a spectacle to watch from the side ships as they systematically released the cannon balls. The volley consisted of at least twenty over cannon balls towards Stalingrad but even the most thunderous sounds were nothing without the strength of the lightning.
Their cannonball hits did not even make a dent on Stalingrad at all. Their cannons literally bounced off from the metal platings of the battleship and dropped into the sea like a piece of useless paperweight.
