When planning the D Day invasion, it was imperative to take out the the six 155mm guns at the top of Pointe Du Hoc. These massive guns were 4 miles (6.5) km) from the centre of Omaha Beach and 7 miles (11km) from Utah beach . They had a range of 15 miles (25km) and so both of the American landing beaches were easily within their range. This post is about the incredible bravery of the Rangers in climbing 100 feet cliffs, whilst under attack and successfully taking out the various gun emplacements at the top. However, the expected six large guns had disappeared!
