... but there was a reason many DD tanks didnt make it to the beach at omaha.. the weather conditions.
The DD Shermans were lost due to a little widespreaded reason. I was a combinition of weather reason and the wave height, the natural water streaming parallel to the coast, the method of orientation used by the crews and the fact they were put into water too far away.
The waves were not that high, that the DDs werent able to swim through it, but once they were not perfectly orthogonal to the direction of the streaming water anymore, the streaming combined with the waves, which made much more water coming inside the DD, so the pump were not able anymor to handle with. So they flipped over and sunk. The Crews used landmarks such as church towers to orientate. They tried to always head straight to it. But when the water itself moves to one direction, the sooner or later you are not orthogonal anymore to the water stream. The last reason is the longer way of the DD Sherman. It is said, there was an order for the landing ships to move close to the shore, so the shermans had less way to travel. But this order came to late to those at Omaha, the Shermans were already in the water. This lead to a longer way and travelling time, which leads directly to a worse angle between the Sherman and the streaming.
