Anky and Remy at liberty

We didn't ride this morning as Jim had an errand to do, so, inspired by the demo yesterday, I took Anky up to the school for some work at liberty.I've done quite a lot of groundwork with Anky, but not recently. She was extremely calm and we started with some leading work, alternating then between leading and driving. She was very responsive and we were using the whole of the school. A couple of times when her attention left me and she stood concentrating on something else, I moved over to her and stood with her for a while until her attention returned to me, then either led her away or stood behind her shoulder and asked her to move from that position.  While we were working, a tractor arrived at the  house down the lane from the school and started unloading some metal scaffolding, it was a hell of a noise and Anky went from 0 - 60 in a millisecond. She's done this before, galloping from one end of the school to the other , skidding into the corners. I stood in the centre of the school quietly, waiting until she calmed a little, then started moving with her, quietly, trying to anticipate her movements and refocuss her attention on me. After a short time she started to look at me and then came in to me. Once she'd come back to me she was calm and we continued for a few more minutes before finishing. I was pleased with the session.
I've been wanting to do some liberty work with Remy, but not had the confidence,so once I'd finished the session with Anky, Jim went up to the school and put a temporary fence across the middle so that I had an area of about 25 x 25m to work in.  I thought this would work better with Remy as he wouldn't be able to get too far away from me, especially if he freaked out at something.  He  was very calm entering the school and I led him around the perimeter and he was unfazed by the new fence so I let him off the rope. He stood with me so I started to lead him around the area with halts and changes of direction until his attention drifted and he wandered off to look over the fence, down the field to the stables. I did the same as I did with Anky, went over to where he was directing his attention and when he refocussed on me, we continued. He was a very good boy, the leading was good and the driving from behind his shoulder much better than I expected. I've been moving him about on the lunge with me in this position so I presume he understood what I was asking him. He did try to turn towards me several times  to keep me in front of him, so I just reverted to leading him, then halted and started again, moving him away from a driving position. I think this work is going to be fun and will really help with the lungeing and in-hand work.
