I now have to confess something that leaves me not a little embarrassed
Speaking with Davie (6pointer) he has quite rightly pointed out that there are actually
three bucks in the series of photos, not the two that I had supposed and happily told you all about.
There is the first small buck in the first photo
Then the second buck (a five pointer) that chases the first away, and that then pursues the doe in the original field, the cut hay field, and the cornfield.
Then a
third buck (a six pointer with a broken top tine), with
another doe, lying down by the hedge that I walked back through in the original field.
So my first inclination that it was the last thing that I expected to see was actually spot on, because it was an entirely different buck and doe!
In looking at the photos I failed one of the fundamentals of stalking - first verify the beast you're looking at!
If that was the bad news, the good news is that there are now at least three bucks in the vicinity of these four fields, though of course it's a bit of a danger to base your population estimate on what you see in the rut!
So, I've fessed up

and very many thanks again to Davie for his powers of observation
