The Battle of the Acid Lakes  occurred during the Periphery Campaign and was a decisive victory for the Dorok military and an ignoble defeat of Kushana's Torumekian forces as well as the Periphery Forces. It effectively ended the Periphery Campaign.
At first Kushana thought the attack was mainly to destroy their airships  and counter-attacks with a cavalry charge . Kushana spots an Ohmu-shell pillbox and sees the Dorok Suicide Troops go inside .
Nausicaä manages to down the Dorok Flying Jar and the wounded Ohmu on a small island in one of the Acid Lakes.  Unfortunately, the Ohmu do not stop their rampage.
When the Valley Gunship returns and tells the encampment that the stampeding Ohmu are approaching , the camp is thrown into chaos as the various airships attempt to escape.
Amid the panic, Kurotowa is forced to shoot men desperate to escape by boarding the Torumekian Armored Corvette . Kurotowa shoots Kushana's Horseclaw and grabs her as she tumbles off  as the Corvett makes it airborne.
Left behind was the bulk of Kushana's forces, including her cavalry, to be trampled to death by the Ohmu. In grief and anger, Kushana cuts off her braid as a pledge of honor to avenge her troops' death .
The Dorok Ohmu-shell pillbox was completely destroyed .
