I do not know who made the photo but I feel very sorry for "Stuffy" (got to love those old boys school nick names) who fell victim to rivalries within the service. His careful husbanding of the RAF and its relatively tiny resources during the Battle of Britain could have easily been undone by less prudent souls who wanted to engage the Luftwaffe in an all out struggle - a very British Götterdämmerung.
But still, even though he was correct in his strategy, his actions and his actions, he was knifed and pensioned off once the battle was won. Such is the nature of intra office politics. I know them well. It is never advisable to succeed at the cost of alienating higher ups even when you were proved. right. Correction....especially when you are proved right. And more especially if you forget to kiss up in a sufficiently self abasing lip puckered manner.
To my way of thinking Dowding's victory in the Battle was similar in some ways to Wellington's at Waterloo especially in the way that Wellington played a defensive game and marshalled his ill trained and piecemeal resources until Blucher reached them. Just as Wellington had planned. Wellington was feted and rewarded by the nation. Dowding was flipped the bird.
