Hans KellerHans Keller writes about the military and political history of twentieth-century Europe, with a particular focus on how ordinary people experienced large events. Over many years, he has studied campaign reports, diplomatic correspondence, and contemprary media from 1939, looking for the junctures where battlefield decisions met political calculation. Growing up with stories from older relatives about air-raid shelters, shortages, and rumours on the radio gave him an early sense that war is lived in confusion long before it is written as narrative. His work reflects a Central European perspective that pays close attention to borderlands, mixed communities, and how maps can change faster than memories. In this book, he aims to bring together operations, diplomacy, intelligence and civilian life into a single, readable account of the invasion of Poland, showing how that first campaign shaped the character of the broader conflict that followed.
