Accusing Peter P of ignorance is fighting talk, Cass. He knows a lot about most things. He will return. (At this point I chuck in Balliol Ballads and Jowett because I know Peter will get the allusion: "if I don't know it it ain't knowledge)./
On Gib:
Aged fourteen I entered a fourth year class called cryptically "The Hive". In the grammar school of the young VE we had the graded A, B and C classes and this extra fourth year "Hive" group of twelve. Intention: take O-levels in 4th year and enter 6th form a year early., Theoretically a Hive student would go to Oxford or Cambridge at the age of seventeen subject to A-level results and passing the entrance examinations required (in those pre-affirmative action days) by both. The entrance exams actually preceded the summer A-levels.
For reasons known only to our tutors the Hive took an O-level British Empire History exam rather than some more broadly defined one. It was an one year syllabus and encompassed the period of British history which started with the Treaty of Utrecht (whenever, whatever and wherever that may be) and ended with the annexation of Uganda (whatever etc.).
Memory fades, but I do think we got Gib under the Utrecht Treaty and, at least temporarily, one of the Balearic islands. I think they got Minorca back
Mind you, and to come clean, I did fail that O-level.
