All hands to the pumps
There is no doubt that the ability to see the raids building was a complete game changer for us even though we were short of resources to deal with them.
The fact that the Germans did not change tactics to combat this shows just how well our Radar 'capability' was a surprise to them. For the first time the Germans were taking looses that were not expected, and indeed this must have been a morale shock after their relatively easy run through France and before. But in the end the final decisions were with the main game players and how they deployed their assets.
We had two well trained former artillery commanders who knew about battle tactics and then later transferred to the RFC. Thus they had the distinct advantage of experience of the bigger picture and were able to adapt this to the defence requirement of the day with different equipment.
The German counterpart was used to an easy European victory with no experience of the larger battle plan. Dowding and Park used all the available resources that were in being and had to adapt a system that was faced with far less warning than originally designed. They were able to adapt the classic artillery tactics but in a unique mobile way and never lost sight of the picture. Considering the vast aerial armada's they had to contend with they used what limited forces they had to good effect and harassed these formations to the point they lost faith in what their own commander was telling them. To a degree it was a huge bluff but then that's what wars come down to sometimes (making less mistakes than the enemy)
With no sight of destroying the RAF the change to another Blitz campaign was not going to achieve what was needed 'Total Air Supremacy'. Game lost and the unsinkable aircraft carrier survived to come back later and bite them hard. Technology is no use without the commanders ability to utilise it to best effect. We had both.
