Seeing no other option, Lieutenant Commander Reddy commanded the pair of destroyers to stage a torpedo attack, which sank an accompanying destroyer, and badly damaged the battlecruiser, before the ships were enveloped in a freak squall, and transported to an alternate world, where humans never evolved, apparently because the Cretaceous–Paleogene extinction event (specifically the Chicxulub asteroid impact) never occurred.
One, the Lemurians, who evolved from giant lemurs from Madagascar, are peaceful farmers and fishermen, and live on huge oceangoing houseboats called Homes.
It was later revealed in Deadly Seas that Amerika was converted to an armed merchant cruiser during the First World War when it was transported to the alternate universe just after battling the British armed merchant cruiser RMS Mauretania in the South Atlantic instead of being stuck in an American port in the world the USS Walker came from.
