There’s a photo on sale on eBay this week. Here’s how the seller describes the image:
"Shows elements of a four nation combined naval exercise in the English Channel. Under the command of Admiral Sir Rhoderick R McGrigor, c in c, the British Home Fleet practised manoeuvering, bombarding, and various other forms of naval warfare. Here, the French cruiser ‘Montcalm’ passes HMS Diadem, as she steams out of the anchorage at Mounts Bay, Penzance.
