The ex-king, Khalifa bin Hamad al Thani, came up with a plan, and we're using the word "plan" very loosely here. Like if you accidentally started a grease fire and then said, "Sounds like a plan!" In that instance, you literally don't know what the word "plan" means. That's kind of what happened when the former emir thought he'd retake the throne.
First order of business? Build an army to storm the castle. This he did by hiring a team of French mercenaries and a group of 600 Bedouin militia members. The only problem? They couldn't find the castle. No one even knew the neighborhood. Even the Griswolds had the sense to bring a map.
"Oh, I see. Now, which side is the entrance where the guards don't check for guns?"
So, the Bedouins stormed the capital city, only to end up driving around in circles. Witnesses claimed they were screaming into their cellphones "Where's the palace?" the whole time.
At least the Bedouins made it to the capital before eventually getting arrested. The French mercenaries didn't even get that far because they lost their boats. Just ... lost them. They walked out of their five-star hotel on their way to the coup and their boats for the ride were gone. Then they presumably went back to their rooms to watch Friends reruns and have a swim.
"Goddammit, Chad! Remember your military training!"
