Joachim Hane

Joachim Hane was a German engineer serving the English Commonwealth. In the introduction to the 1896 edition of The Journal of Joachim Hane, editor C. H. Firth describes him as a foreign military engineer whose skills were valued in the Civil War era, when both sides relied on experienced continental officers for artillery and fortification work.

Hane is remembered for his journal, which records his "escapes and sufferings" while employed by Oliver Cromwell in France from November 1653 to February 1654. The work survives from a manuscript kept at Worcester College, Oxford, and is notable as a firsthand account of espionage, political tension, and travel under constant risk.

Little else appears to be firmly documented in the sources I could confirm here, so his reputation rests mainly on that remarkable narrative. Even so, the journal gives him a distinct voice across the centuries: practical, observant, and closely tied to the turbulent world of Cromwellian diplomacy and war.
