An excellent resource, a bit like Foyles used to be (perhaps still is) in London. I was particularly pleased to find the US author James Mrazek on Eban Emael. The strategic importance of this action (securing the crossings, the impregnable nature of the Fort, the probability that had the action failed Allied forces could have counter attacked and, without the bridges held the northern advance) reassures me of the critical importance of EE in the rapid overthrow of France.
