Free History Books

I received this notice from Pen & Sword Publishers today.  I have not tested the offer, but I can vouch for its authenticity.  So if you are into Napoleonic history, and would like some free books (ebooks actually), then go for it!

Good Morning!
This Sunday marks the anniversary of Napoleons death, to coincide with this anniversary Pen and Sword will be giving away four eBooks for free from Amazon. I wondered if you would be able to share this with your readers, if you are doing a post around this anniversary. It’s not often we give away eBooks for free, so I am keen to spread the word as far as possible! Here’s the four eBooks that will be free on the day and the Amazon link to download the titles.
Have fun on Sunday (UK or US timezone I presume)
