Two books planned:
1. The Lines of Torres Vedras. Which will include recent research in the UK and Portugal and also look at the French and Portuguese plans for the defence of Lisbon.
2. Wellington's Last Siege. The Siege of San Sebastian 1813. This will include previously unpublished archival material and the latest research on the siege.
​These will be published late 2021 / 2022

I am just finishing my next book which will be on the Napoleonic Services of John Burgoyne RE. Most of it covers the Peninsular War 1808-14, Burgoyne being present for most of this time.  As well as looking at the engineering aspects it does take the opportunity to look at some other contentious issues from the War.
​It is due to be published in the first half of 2020 by Helion.
