Correction. Manchester also hold a battle honour.Apologies for going off at a bit of tangent to the main theme of this thread (which in itself is fascinating).
Militarily I have pretty much done things in reverse. As a young man I served as a regular in the Royal Engineers and eventually left to go into higher education as a mature student. Rather than get a bar job to pay my way I joined Cambridge UOTC as they had an RE wing, so I continued to get paid for building bridges and blowing things up and attending exercises in Ascension Island and Belgium and generally working attached to other RE field units and attached leadership with infantry units.
The CUOTC was initially raised in 1803 in reaction to the Napoleonic threat at that time but played no general part in that particular theatre. Fast forward to 1899-1900 and the second Boer war was in effect, a detachment of CUOTC volunteers sailed from Southampton on the 7th March 1900 and was attached to the Suffolk Regiment. In that capacity they joined in the siege of Pretoria and after this they were deployed in an anti-guerrilla capacity defending railroads from Boer commando attacks. They were then deployed again with the Suffolks in an attack on a Boer position at Barberton and played a sniping role in relation to the retreating Boers due to their shooting skills. After Barberton they were largely relegated to generic stagging on duties as hostilities generally wound down.
The volunteers were back in Cambridge on 6 May 1901. All the Volunteers were made Honorary Freemen of the Borough of Cambridge and on 21 December 1904, three years later, CURV was granted the battle honour "South Africa 1900-01". In 1908, CURV was renamed Cambridge University Officers' Training Corps and remains the only Officers' Training Corps to be awarded a battle honour ( in light of other comments I have to assume that this honour is UK based only).
There is a good generic history on the CUOTC: Amazon product
