I'd like to thank Google for that accuracy.
Am I right in reading two French admirals, one British and no Italian? I suppose that could indicate an ad hoc formation - or me attaching too much information to the flags!
Yep...mostly because I don't know the second flag of the British Mediterranean Fleet in 1887 (though I actually think there might not have been one) or any Italian commanders of the period.
I know the French first flag (Vice-Admiral Peyron) and second flag (Rear-Admiral Devaresse) thanks to poring through Brassey's Naval Annual of 1887 online; they're mentioned as being the commanders during maneuvers, so I stuck with them.
The British flag, interestingly enough, is HRH the Duke of Edinburgh, and a certain Lieutenant who might hypothetically in our world have become George V is serving alongside his uncle in Alexandra. If he's not careful, I might have to figure out some alt-successions to the British throne...
