Many military historians who are interested in D Day facts discuss how the weather impacted the D-Day invasion. In addition to delaying the invasion by one day, the weather blew the boats of the Allies east of their planned landing targets. This was especially true for the Utah and Omaha beach landing targets.

21. The Terrain of Omaha Beach Caused the High Number of Casualties

d day facts

Omaha Beach was one of the areas where the Allies suffered the most casualties. The geography of the area played a role in the high number of casualties at Omaha Beach.

High cliffs that lined the beach characterized the geography of the Omaha Beach landing target. Many American forces lost their lives because the Germans had gun positions on these high cliffs.

23. Over 2,400 American Soldiers Were Killed on Omaha Beach on D-Day

d day facts

D Day facts reveal that over 2,400 Americans were killed or injured on Omaha Beach. This was as a result of the geography of the Omaha Beach landing target, and the weather that had blown the ships off their target.

The weather had also led to the sinking of some tanks which were intended to provide support for the troops landing at Omaha Beach.

The high number of casualties at Omaha was also in part due to the lack of artillery providing reinforcements for the troops.

24. Germans Had Less Casualties on D-Day Due to their Positions

Due to their positions, the Germans suffered fewer casualties than the invading Allied troops at Normandy. However, the Germans had no reinforcements to help them retake positions.

Once the Allies had landed at Normandy, they took control of the beaches and continued until all of Europe was free.

The massive scale of the D-Day invasion and its important role in World War II make D Day facts fascinating, even today. Many people lost their lives fighting on the fateful day of June 6th, 1944.

Many people wrongly like to say that D-day was the turning point of the war in Europe, for WW2. Which is wrong. But the the time D-day came around, the Germans have been in full retreat from Russian forces, for almost a year. A more accurate state would be that the battle of Stalingrad was the turning point of the European theater, of WW2.
