It was decided that OTC (Officer Training Corps) at a good school was sufficient training for a junior officer, and hundreds of such public schoolboys were given commissions straight away.
That 'temporary situation' caption is brutal.
The initial premier of blasting the Germans to little pieces was impossible with the tech of the time.
Fire two shells a minute for an hour, at ~20kg a shell, plus a couple kg for the shell-boxes, and that's a quarter-ton per gun, and a ton per battery. Early wave Wehrmacht used 3 battalions of 12x10.5cm leichte Feldhaubitze, so 36 guns is nine whole tons of ammunition gone in an hour, without even considering the 15cm battalion they also had, or the weight of mortars used down the chain. So that's about four trucks loaded with ammo that need to arrive on the hour every hour to keep that division in supply just for the 10.5s, assuming everyone is conveniently located. Keep that firing up for a day of heavy combat and you're going to need a train load to replenish that unit by itself.
Similar thinking happened in WWII, Vietnam, and countless other places where it was assumed that putting enough explosive into a target area will do the job, no problem. They also had few answers to the question: "What if it doesn't?"
