Sorry about that.
Don't worry about the stuff & money, you are all fine and that's what counts. Unless it's a videogame, playing hero is the dumbest thing.
I don't know about your bandits, they sound calm and professional from your words. Crazy thieves are the most dangerous, because they lack the nerve and can make a mess out of nothing. Some years ago a friend of mine was threatened by a junkie waving a syringe in the air asking for money. My friend, seeing he could get infected with AIDS and heaven knows what else, dropped the wallet and run away before it hit the ground.
