H-hour (D-day)

This article is about the H-hour of Operation Overlord. For the general military designation, see H-hour.

H-hour was the name given to the airborne assault in the Battle of Normandy. It included the American 101st Airborne Division and 82nd Airborne Division With the British 6th Airborne Division. This took place about three hours before the main beach landings on the Normandy. The Airborne invasion consisted of over 50,000 men and around 1,200 planes and gliders. The combined assault of British and American Airborne and glider divisions would surprise the German defenders and cause enough havoc to make the beach landings go more smoothly. .

Objectives of H-hour

The divisions of paratroopers that landed each had an objective:

The 82nd Airborne would drop and take the town of Sainte-Mère-Église and protect the right flank on the American beach landings of Omaha and Utah beach. After doing that, they would link up with the 101st.
The 101st Airborne Would be dropped behind Utah beach, to secure the beach exits and be prepared to exploit through the town of Carentan.
The British 6th Airborne Division would be dropped between the river Orne and some high ground of the Bois de Bavent to secure the eastern flank of the British and Canadian sector.

Dropping the troops

When the airborne divisions were dropped, there were many mis-drops. Some were dropped as far away from their designated DZ (drop zone) as 20 miles. Some were even dropped in the English Channel. Often, the C-47's and modified B-23's that were used in the drops came under heavy fire and were forced to drop their Airborne members prematurely. Pilots were often heavily criticized for this. Another reason why many mis-drops occurred is because, while crossing the English Channel the transport aircraft's formations ("flying V's") flew through low lying clouds. The lack of visibility caused pilots to often drift away from the lead plane to avoid a crash. This caused many pilots to have their bearings off and flying just a few degrees off course, which added up when this was done for several miles.
