Here is what happened, pardon the details but usually "the devil is in the details".
Went into pasture with a herd of 6 and when entering, this 4 years old gelding Joey, was at the gate. He is new to the farm - he usually walks away when he realizes I am not taking him, but this time he aligned his shoulders with mine, stayed to my left side about 8 feet away, and matched me stride for stride for about 2 straight minutes - about 1/2 way through the pasture. If I slowed, he slowed - but it wasn't a good feeling like when I am leading my horse. I stopped walking b/c I wasn't sure what the hell to do. His right eye hadn't left me the entire walk and when I stopped, I saw him snake his neck down and towards me - the only time I have ever seen this posture was when I saw one gelding attack another. I said "joey, shoo" and that was it. He spun on a dime, kicked out with both back legs, so I got pounded with mud and rocks in my face. I kind of spun around and the hit the outer wall of the run-in, while Joey ran down to the end of pasture and ran the entire herd toward me. When they ran by, he was looking at me, ears pinned, lowering that head and he took another kick at me as he went by the run-in.
Finally, the barn manager hears me screaming and he comes out, so Joey decides to go after him. Jazzy, my filly, was smack behind me scared as I was and Joey saw us walking and he came after Jazz. The barn manager had only a lead rope and he somehow intimidated Joey enough for me to get out, while he got Jazzy for me.
Then I stood there shaking and wondering: what the heck just happened and what the hell did I do to set that horse off?
When I went to put Jazzy back in pasture, alone b/c the manager wasn't there anymore, I took my lunge whip. Joey was at the gate and I smacked the ground in front of the gate with the whip, I hit the gate with the whip; everything but him - he backed up, when he felt like it, about 10 feet. Then I waited and he finally turned around and walked away so I could let Jazz in.
I will no longer go into a pasture without something in my hand I guess; Jazz follows without a halter/lead so I usually hang mine on the gate, go get Jazz, we stroll on back and I halter her to walk her to the barn/arena... besides that, I am really at a loss as what I am supposed to do when I go back there today.
If you have a moment, and can share your thoughts, I would be so appreciative.
