Welcome to the home page of David Flintham BA FRGS. 

I am a military historian, specialising in 17th century fortifications and sieges.

The 17th century was a watershed in European history: it was the century where the superstitions of the medieval period were largely laid to rest, to be replaced by scientific reasoning. The origins of the great transformations of the 18th and 19th centuries (the Enlightenment, and the Agricultural and Industrial Revolutions) can be traced to the 17th century. The transformation on the battlefield was no less dramatic – military engineering which was regarded as an ‘art’ during the 16th century was very much a science by the end of the 17th.

The military history of Western Europe in the 17th century is dominated by the Eighty Years’ War, the Thirty Years War, the Wars of the Three Kingdoms (misleadingly, but commonly, known as the ‘English Civil Wars’), and the wars of Louis XIV. The common perception of these conflicts is of big battles: cavalry charges on the wings whilst in the centre, massed infantry formations slugging it out. Yet the reality is rather different as it was the siege rather than the set-piece battle which dominated 17th century warfare.

This site is home to my research into the sieges and fortifications of the 17th century.

'Rediscovering London's Lost Civil War Defences' - a talk by David Flintham at the Cromwell Museum on 16th June 2021. 

After the frustrations of 2020, 2021 is already looking very promising with exciting developments in both London and King's Lynn, as well as the new Centre for Experimental Military Archaeology.

My biography of Richard Clampe (who designed King's Lynn's fortifications following the siege of 1643, and later went on to plan the Parliamentarian siege-works around Newark upon Trent). This has been published in Fort (volume 46), the journal of the Fortress Study Group.
