Versailles disarmament and the Reichsmarine personnel system

The Treaty of Versailles was designed to leave Germany incapable of offensive action while encouraging wider international disarmament. It capped the army at 100,000, abolished conscription, dissolved the general staff, and imposed long minimum service terms so Germany could not quietly create a large trained reserve. The Rhineland was demilitarised, fortifications at places such as Heligoland were restricted, and military aviation was prohibited. At sea, Germany could retain six pre-dreadnought battleships, six light cruisers, twelve destroyers, and twelve torpedo boats, but no submarines. Naval personnel were capped at 15,000, including only 1,500 officers and warrant officers. These restrictions explain both the Reichsmarine's emphasis on retaining skilled cadres and the political importance attached to each replacement hull.
