At that time, I unchambered the round in my handgun and holstered the weapon.
Why did you unchamber? Do you always carry with no round in the chamber?
I've been in the same situation. Going to my stand and saw a reflection, used my binoculars to see a guy in my stand aiming a scoped rifle at me.
The circumstances were different as an oak tree that would definitely constitute cover was immediately to my right. I took that cover. From that point I was able to approach my stand in concealment from the rear of the stand. The leaves were wet from a recent rain and I could thus approach with little sound.
Another oak tree provided cover close to the rear of the stand. I told the tresspasser to unload his rifle, throw the ammunition on the ground and to use the rope tied to the stand to lower his rifle to the ground. And to hold his rifle by the muzzle in his right hand and leave immediately and never return.
I was miles from cell phone coverage and just wanted the man gone from the property.
Personally, I won't attempt to prevent a person from leaving in a situation where I am alone. In most situations I will instruct the person to leave.
I understand holding the trespasser for the police. In view of the likely response time though, I think having him unload his weapons and then leave might have been more prudent. Have him drop his pants around his ankles and shuffle off hobbled.
I'm not criticizing though. Just pointing out alternatives. That was a stressful forty five minute wait.
I've seldom approached trespassers. I prefer to observe from concealment. When I'm with friends, one of us would approach them while being covered by others from concealment and cover with an agreed unobtrusive movement being the signal that the trespassers are hostile and about to initiate violence. Luckily that signal has never been given.
When I'm alone, trespassers don't see me if I see them first.
