I think it was in Andy Mcnab's autobiography, where there was a story of a British SAS (Elite special forces) soldier who came home from an overseas tour to find squatters in his house. Apparently he sent flowers to them while they were in hospital.

Yup that was in France. Now with the law of 2023, it's significantly easier to deal with squatters.

Be careful though when hiring goons, you might get involved with the wrong kind of people.
