For 63 Days Berlin Was Only Soviet Controlled | What Happened Before the Allies Arrived?

After the surrender of Adolf Hitler’s Germany in World War II, the devastated capital Berlin remained solely under Soviet Union control for 63 days. During this brief but crucial period, the Western Allies had not yet arrived.

Factories, military technology, classified archives, and thousands of German scientists and engineers were seized and transported back to the USSR.

This controversial chapter of postwar history raises important questions:
What exactly did the Soviets take from Berlin? How did this shape the early Cold War? And why were the Western Allies absent during those critical 63 days?

Why WWII US Tank Crews Added Sandbags — And Why General Patton Hated It.

During World War II, American tank crews often improvised extra armor using sandbags, logs, concrete, and spare track links in hopes of surviving deadly battlefield hits. While these battlefield modifications boosted crew confidence, General George S. Patton strongly opposed the practice, arguing the added weight reduced mobility without providing real protection.
