William Vandivert photographed for LIFE from the late 1930s through 1948. In April, 1945, as Russian and German troops fought — savagely, street-by-street — for control of the German capital, it became increasingly clear that the Allies would win the war in Europe. Not long after the two-week battle ended, Vandivert was on the scene, photographing Berlin’s devastated landscape.

Hundreds of thousands perished in the Battle of Berlin — including untold numbers of civilian men, women, and children — while countless more were left homeless in the ruins. But it was two particular deaths, that of Hitler and his longtime companion and (briefly) wife, Eva Braun, in a sordid underground bunker on April 30, 1945, that truly signaled the end of the Third Reich.

Vandivert was the first Western photographer to gain access to Hitler’s Führerbunker (translation: “shelter for the leader”) after the fall of Berlin, and a handful of his pictures of the bunker and the ruined city were published in LIFE in July, 1945. A few of those images are re-published here; most of the pictures in this gallery, however, went unpublished — until now — and illustrate the surreal, disturbing scenes Vandivert encountered in the bunker itself, and in the streets of the ruined, vanquished city beyond the bunker’s concrete walls.

Oberwallstrasse, in central Berlin, saw some of the most vicious fighting between German and Soviet troops in the spring of 1945.

An American soldier, PFC Douglas Page, offers a mocking Nazi salute inside the bombed-out ruins of the Berliner Sportspalast, or Sport Palace. The venue, destroyed during an Allied bombing raid in January 1944, was where the Third Reich often held political rallies.

At the Reichstag, evidence of a practice common throughout the centuries: soldiers scrawling graffiti to honor fallen comrades, insult the vanquished or simply announce, I was here. I survived. Berlin, 1945.

The first of the approximately 20 pages of notes that William Vandivert typed for LIFE‘s editors in New York, describing not only the pictures he took but also the atmosphere pervading his examination of Hitler’s bunker and the Reich Chancellery grounds. (An example of Vandivert’s terse, vivid notations: “… view of chancellery palace … completely bombed, burned and shelled to hell.”)
