Fear God and Dread Nought

I've always been fairly well read on the Royal Navy with the Great War being no exception so I was not expecting to be learning too much from an Osprey publication. This one was entitled 'British Dreadnought Vs German Dreadnought' and subtitled 'Jutland 1916'. It is from their 'Duel' series and I expected to read a fair comparison between them.

A fair comparison between the equivalent ships in the two fleets it was too albeit at a fairly low level of detail. Nothing much to write home about! At £5.76 plus postage I was not expecting too much at all.

One little detail did catch my eye as a possible typo. No it was definitely an error I thought. I even checked some of my other sources just to be sure. A quick peek through my copy of Janes confirmed my suspicions.

The Osprey stated that HMS Agincourt had a main battery of 14 guns each of 14" calibre. Nope said my memory banks, fourteen 12" guns is what she carried and both Wikipedia and Janes agreed with me.

Now if an Osprey approved author can make a simple mistake like that in a publication then how many other mistakes are there to be found in this publication alone. I will not be spending any of my precious reading time in trying to find out.
