I was out to dinner with Col. Douglas last week and I took the opportunity to raise with him the question regarding whether or not your grandfather was in 16 Platoon, D Company. I also showed him extracts from your blog regarding your grandfather and the photographs on there of your grandfather.
Unfortunately, whilst he said the name rings a bell, he said he couldn't really remember. He said it was easy to remember those who were "very good" or those who were "very bad", but difficult to remember the bulk of the men who just went about their business quietly and efficiently, as they should.
He did say that if Sergeant Little MM was your grandfather's sergeant then in all likelihood he was in 16 Platoon. Whether he was on the Haalderen raid would be more difficult to say. The likelihood is that he would be there if he was in 16 Platoon but inevitably there might be one or two men left behind for all sorts of reasons.
He said the only way you might be able to find out more would be to track down Corporal/Sergeant Mellor DCM (who took over as Platoon Sergeant from Sergeant Little) or a member of his family if he is no longer alive. He may have kept in touch with people post war. As Col. Douglas went to Africa with KAR after the war and then joined the regular army a couple of years later he rather lost touch with many of his men, and in those days it wasn't so easy to track people down.
He did comment on some parts of the blog. He's pretty certain that measuring the depth of the water would have been on The Island, near Nijmegen, after the Germans had breached the flood defences and there were spring floods. He says it would be unlikely to be Rosendaal as there was no water of significance, or at least which was a problem there.
He also thinks that the wounding on 7th April 1945 may not have been in Nijmegen itself but nearby, on The Island, whilst clearing it prior to the liberation of Arnhem. Your grandfather may have been taken to Nijmegen for treatment. Nijmegen at that time was pretty safe, he recalls, and the clearing of The Island started on around 2nd April 1945 and there were pockets of localised fighting for a few days thereafter as they push up across The Island.
Col. Douglas says that Sergeant Little was his third Sergeant of the North West Europe campaign, Sergeant Mellor the fourth. The first lost his life in the fighting around Fontenay/Rauray, the second to the East of Caen (whilst Col. Douglas was at an 'O' Group meeting and he was waiting outside, a stray mortar shell came literally out of nowhere on a quiet day and it was a direct hit, leaving in Col. Douglas's words, pretty much just his boots and his weapon). Sergeant Little, as you know, was killed immediately on landing behind the enemy lines at Haalderen. Apparently he shouldn't have actually been the first man off the boat, he should have been the last man off, to make sure that everyone else got off, but he was very eager.
I'm sorry I can't have been of more assistance.
It’s a wonderful thing this military research, frustrating and confusing at times, but thoroughly absorbing and on occasions such as tonight highly satisfying!
