real invasion of sark feel:

In late August 1990, an unemployed French nuclear physicist named André Gardes, armed with a semi-automatic weapon, attempted an invasion of Sark. The night Gardes arrived, he put up two posters declaring his intention to take over the island the following day at noon. The following day he started a solo foot patrol in front of the manor, in battle-dress, weapon in hand. While Gardes was sitting on a bench waiting for noon to arrive, the island's volunteer connétable approached the Frenchman and complimented him on the quality of his weapon.[24] Gardes then proceeded to change the gun's magazine, at which point he was tackled to the ground, arrested, and given a seven-day sentence which he served in Guernsey
