There is truly no end to British Napoleonic Wars historiography. There’s absolutely more written about British forcers and battles between 1800 – 1815 than there is the whole of 1700 – 1800.
For the Victorian period, or really the period from Waterloo until the Second Anglo-Boer War, it seems that scholars can’t get enough of the Anglo-Zulu War of 1879. It is done to death. New books about Isandlwana that promise to shed new light on the battle, authors trying to one-up each other, etc. It gets bloody tiring.
