In case it's faded into memory, there was a Second Supplement to The London Gazette, dated 28th June 1991 (Number 52589) which gives a great overview of the whole of Op Granby. Thud and Blunder, our contribution gets a mention on what shows as page 44.
Apologies, I can't post the proper link as I haven't reached the magic number of posts yet, but a google search should bring the document up.
