Race to the Sea

during ww1, king albert from Belgium decided not to let Germany pass through Belgium....King Albert responded with "Ok, lets flood the damn yser river!"

it's also a song by Sabaton on the war to end all wars album

Belgium soldiers: blow up the dam!
*explosion*
German infantry: Run! they flooded the river

that's basically what happened with the Race to the sea tho it's not a race
