The World War II Foreign Military Studies collection on Footnote includes several insights into the German perspective of the D-Day invasion.

One is this Telephone Diary of the 352 Infantry Division. It begins with early reports of paratroopers and personnel carrying gliders and then continues through the invasion by sea.

The first reports of ships came in at 5.02 Hours, "Off Port en Bession one big and four smaller naval units were sighted. Ahead of Grandcamp light naval units are reported." At 5.20 Hours, "Advanced observers of the 2 and 4 battalions of the Artillery Regt 352 report to have ascertained noises which probably originate from naval units, at approximate distance of two KM, heading toward the Vire outlet."

The attached image is the first page of this Telephone Diary. You can read the rest using the filmstrip at the bottom of the viewer.
