Suppose what we class as a defeat..and if it was a military defeat. Suez was not a military defeat as such unless were talking the Egyptians, politically to Brits and French obviously. Goose Green at the time....The Argies did what they had to do and surrendered, the guys on the ground had no way of knowing what faced them thanks to their overall command. Spion Kop...now yes...theres one I would not think of straight away but yes a major humiliation. In fact the Boer war in general. Belgrano....I would think the Argies were on a mission to take out a major British surface vessel. The loss no matter what shouting by all and sundry later was acceptable in such a mission and no loss of face should be attached to it on their part. The silly shouting about exclusion zones afterwards is not worth the amount of words wasted and wrtiten on it.
