I've got a couple of pictures of the Moehne Dam that also show where the breach occurred, I'll post them later tonight.
The thing that struck me in comparing the Moehne and Eder attacks is that - defensive aspects aside - the Eder was the more difficult to hit, given the topography surrounding it, which, amongst other things, meant that the breach occurred off-centre as shown in my photo above.
Standing on the wall of the Eder for the first time on 17 May 1993, I could only wonder how a successful attack was achieved exactly 50 years ago to the day (night,) at 60 feet, in the dark, and with basic (by today's standards) navigation equipment.
