John and Michael,
I do not have access to my meagre book collection at the moment.
But I recall the 28th cut theirs on board transports bound (as they found out subsequently) for Portugal in 1808.
Ed Coss refers to this incident in All for the King's Shilling" citing Cadell
There is an account somewhere of troops on board transports in the Solent receiving the news and pigtails being cast overboard en masse to the sound ot cheers resounding round the fleet.
