Wehrmacht

This series traces how the Wehrmacht's reliance on a wide variety of complex, poorly standardized vehicles created a logistical nightmare that severely hampered its mobility and operational effectiveness.

Germany's final offensive in the West was predicated on a single logistics assumption: capturing American fuel depots at Stavelot, Spa, and Antwerp. When the fuel didn't fall, the offensive died—literally running out of gas.

The largest military operation in history was crippled not by Soviet heroism alone, but by a 89mm difference in railroad gauge width that made German supply lines progressively useless as the advance continued.
