Giant Cryptic Holiday Collection No 69 (UK Edition)

65a Relented and acquired right to be replaced by first three escorts

Acquiesced.

first three esc orts ; acqui r ed - acqui esc ed

63d = rocking
You should have the following letters R?C?I?G from:
62a = bracelet
65a = acquiesced
68a = dramatist
71a = slang

The following words can be made:
1. racking
2. recking
3. ricking
4. rocking
5. ruching
6. rucking

I think ROCKING is the only word with relevance to horse, hence my pick.

..."shocked by" = "rocked by".

Thanks Dutchy. I thought it was rocking.
