The numbers of tanks in Britain awaiting the threatened German invasion seems to be a subject of much debate, with conflicting numbers quoted in different sources. Is there any agreement on the numbers, on a month by month basis ? And what type of tanks were they ? This matters because the Matilda II was one of the best tanks in the world at that stage in the war, arguably better than any tank the Germans had, but some of the other British tanks weren`t quite such good quality. I have to admit I`m one of those who thinks Sea Lion was a huge bluff (to put pressure on the British to come to terms), and even if it had taken place the RN would have pout a stop to any nonsense relatively quickly, more or less regardless of the numbers and quality of British tanks, so this question is more out of interest more than anything.
