Holland was occupied by Germany in WW1 and WW2, so I'm thinking Operation Chowhound (an American sounding word) might have been some sort of Allied operation to liberate Dutch territory from the Germans.
It was an operation mainly by the USAF to drop food to people in South and North Holland who were literally starving. This was in the Hunger Winter of 1944/5. Operation Market Garden had failed and the Germans were still occupying parts of Holland and shipping everything not nailed down to Germany.
An agreement was reached with the German Luftwaffe and antiaircraft defences to let these unarmed planes travel a specified route dropping the food. The food was dropped without parachutes so it would not be blown out of the agreed drop zones. Saved hundreds of thousands of lives I imagine.
Much of Holland is below sea level as most of us know. Sea levels are rising tho the North Sea levels on the Dutch coast have actually dropped a bit, result of a weird gravity effect.
Dyes, flood control mechanisms (e.g. the barrier to protect Rotterdam) etc etc are used to protect Dutch land from the sea, some polders are no longer used for agriculture to let rivers (Rhine) flood them, reducing flood levels in polulated areas.
What is the Dutch government’s ultimate plan to protect the Dutch population from rising sea levels?
