A first‑hand diary by a long‑time confidant of the German chancellor, compiling twenty‑five years of official and private intercourse into daily notes, reproduced documents, and restored passages. It chronicles diplomatic negotiations, cabinet deliberations, and episodes from the Franco‑German conflict while interweaving candid character sketches that acknowledge political skill alongside personal faults. The work foregrounds behind‑the‑scenes decision making, the routines and culture of diplomacy, and the personal networks that shaped policy, aiming to provide an eyewitness, document‑based account rather than partisan eulogy or sustained criticism.
