that may have cleared things up... At 93,he is 'all there up top'but he has had a mild stroke which has slightly affected his speech and coupled with the fact that he is in hospital with other older folk,it can be hard to hear him sometimes (above other peoples visitors speaking loudly to their loved ones, obviously with hearing defects....)
From Burton Marshes thread : 'The area is literally covered in the small inert practise bombs. The area was also a Luftwaffe bombing decoy, and was laid out with overhead electric lights that reflected on water filled ponds, that were laid out in the shape of Garston Docks on the Mersey, to act as a decoy. It was very succesful, and there are local reports of "hundreds" of bombs being dropped overnight, over a period of a month'.
I think this is possibly what he is referring to. Thanks again.
