The Ministry of Munitions, First World War

de bene esse: literally, of well-being, morally acceptable but subject to future validation or exception

In the First World War, it wasn't enough to out-fight your opponent - you had to out-produce them too. This meant that shell production in the early years of the war was crucial, and a new Ministry, the Ministry of Munitions, was created to meet this demand.
