After a little bit of digging I was able to find a good quantity of GHQ WW2 naval vessels in various states of disrepair. Many of them look like this:
The top pic shows, from the left: a King George V class battleship, a Caio Duilio class battleship, a Littorio class battleship, and a Strasbourg class battlecruiser. The second pic shows, clockwise from the top left: Hood battlecruiser, Texas class battleship, Arkansas battleship, and a Graf Spee class pocket battleship.
Quite a disparate bunch. Unfortunately, Littorio and Strasbourg have various amounts of paint, which would need to be stripped as I am certain that I no longer have those hues in my collection. The others pictured above, along with Rodney and Barham, are bare or in primer.
The ships I have lean somewhat towards the Mediterranean campaign, but another idea struck me while digging for these miniatures. I found this magazine during the search:
Inside, there is an interesting article:
The article details the planning that occurred in 1941 when policy-makers in Washington DC thought that Brazil might become pro-Axis. While it seems to be a stretch of the imagination today, the population of Brazil contains a number of German emigrants and some of the Brazilian army officers were thought to side with the Germans.
The map above is perfect for the task, detailing airstrips of various sizes and the capacity of the ports. The real task is assembling the miniatures for the campaign. GHQ makes most of the US ships - including Texas and Arkansas which I have in my possession. Panzerschiffe makes the Brazilian dreadnoughts Sao Paulo and Minas Gereas.
There is a lot of room for adding more forces to this what-if scenario. Some of them are mild, such as adding German aircraft squadrons and U-boats. Some are wild - adding Graf Spee and Prinz Eugen to the Brazilian fleet. And there is the truly fanciful, with Bismarck and French ships making their appearance. But I have to admit that the strangeness adds to the appeal, for me at least.
