It's strange how life just keeps repeating itself. I just read about this very thing. The only difference was that the ministers name was Haldane and it happened just before WWI.
$1:
In December 1905 Haldane was appointed Minister of War, a post he retained until 1912. Haldane used his portfolio to institute a series of vital military reforms, including the creation of the Territorial Army (many of whose units went off to war as part of the British Expeditionary Force), the Officer Training Corps and Special Reserve, in addition to the British Expeditionary Force (BEF). He also effected great strides in the provision of army medical and nursing facilities.
When war arrived in 1914 it was largely thanks to Haldane's earlier planning that the BEF was able to mobilise for war as quickly as it did.
