Gorlice–Tarnów
2 May 1915 — Mackensen’s breakthrough on a 50-km front unhinges the whole Russian line. By September the Great Retreat has surrendered Poland, Lithuania and a million prisoners — and made Russia’s home front a rumor mill of treason.
THE MOMENT IN CONTEXT
With the west locked, 1915 is the year everyone looks for a way around — and the war metastasizes. At Ypres in April, Germany opens a cylinder valve and the age of chemical warfare begins (the memorial marker stands at Langemarck). In May, Italy — bought by the Treaty of London’s promises of Austrian land — joins the Entente and attacks up the one corridor available: the Isonzo river, a limestone trap it will assault eleven times. And at the Dardanelles, Churchill’s great idea — force the straits, take Constantinople, open the warm-water road to Russia and knock the Ottomans out with one blow — dies on the beaches of Gallipoli, where Anzac and British infantry cling under the ridgelines for eight months against an Ottoman defense organized by Mustafa Kemal, and never take them.
From Chapter 4 — The Widening War of The Great War, 1914–1918 (NOV 1915).

- What it changed — Russia wounded where it cannot heal. The army recovers — 1916 will prove it — but the home front does not: refugees choke the cities, inflation eats wages, and the Tsar at headquarters…
Then ask the room: Gallipoli: a brilliant strategy ruined by execution, or a bad idea rescued by nothing? The argued answer is on the chapter page →
