Hello, Elle!
My thoughts exactly about Sandy.
A sick thing to do, but that was then, this is now.
All horses over the age of 12, and the sick and injured horses, were shot.
Some of the men shot their horses, but most were sold.
There is a statue, I forget the town's name, to the most famous Waler (apart from Sandy) called "Bill the B?s?a?d".
Bill was a hero! He carried five men to safety one time.
There is a book about Bill on Amazon.
Only one horse got back to New Zealand, a mare called Bess.
I am going to see what I can find out about her.
