The assault on the bridges at Benouville is a moderately well known story of D-Day; it is featured prominently in the film
The Longest Day (and the book the Longest Day is based on) and is well covered in Stephen Ambrose's most excellent book
Pegasus Bridge. There are links to Amazon for these at the bottom of this blog entry.
The short summary for those who are not familiar with the story is this: the first troops to land on D-Day were members of a British Glider company, commanded by Major John Howard. They were to land, in 6 gliders, at two key bridges which, if captured and held, would keep the Germans from hitting the flank of the British forces advancing from the beach. They were to hold until British special forces, advancing from the beach, relieved them. Though they were pressed hard by the Germans, they succeeded. The French subsequently named the bridge Pegasus Bridge, a reference to the emblem of the British Paratroopers.
This first photo is of the modern bridge located on the site of the original bridge:
This photo shows two of the three stone markers where three of the gliders landed next to the bridge, and the bust of Major Howard. The strip of land they put down on is quite narrow, the piloting of the gliders was truly impressive (the other three gliders landed next to another bridge on the same road; the road crossed a river and a canal in short order, and both bridges needed to be taken.)
The original bridge was not sent out for scrap, it is now located on the grounds of the nearby museum devoted to British Paratroopers:
The glider used in the assault was a British model called the Horsa. They were all destroyed in the cleanup of the battlefield; designed as use once devices, they'd been used and were now litter. None survive, the "Horsa" at the museum is a reconstruction:
