:G'day, I probably don't have the content knowledge to contribute meaningfully to that debate, although I do agree that it would probably be okay to call it the "Battle of Olongapo". Unless a source calls it something else, it seems to make sense to call it that as it is reasonably descriptive as to what it was. Whether it should be merged or not probably comes down to the level of coverage. If it is well covered as a single event, I'd say it would be best to leave as is. If not, then maybe a merge is warranted, but then it needs to be considered if there is in fact an article that it could be merged into. Regards,
