I think you are referring to Slapton Sands in April 1944 and the rehearsal for the Utah Beach landings code named 'Operation Tiger'. This ended with the loss of nearly 1,000 lives following a lightening attack on the exercise by E-Boats operating out of Cherbourg. Ken Small 'The Forgotten Dead' is a book about the recovery of the Sherman Tank that now stands as a War Memorial at Slapton sands. A splendid read about the dedication of one man to uncover the truth. The site was chosen, in 1944, to replicate the beach landing and the inundated area that lies between the beach & land, which the US forces would then arrive at in France.
Oddly, US Marines were not used in the amphibious landings in the Mediterranean, Sicily, Italy, Normandy nor Southern France. And for most of the Pacific amphibious landings, the Marines were used most of the time and not the US Army. Kinda odd.
D-Day is thought to mean an amphibious landing (which is not the case). There were many amphibious landings in the Pacific Theater as each island had to be taken. Sometimes there were multiple landings for one island or chain of islands. This is why the Marines played was mainly used in the Pacific and not in the European theaters.
The Normandy Landings on 6 June 1944 were significant for several reasons. Historically, it is the largest amphibious military operation in history. Strategically, the landings opened a second major front in the European theater, taking pressure off of Soviet forces on the Eastern Front and spreading German troops and resources across two major campaigns.
During World War I, the Navy conducted amphibious operations primarily in the Dardanelles Campaign, notably at Gallipoli in 1915. This operation aimed to secure a sea route to Russia and to open a new front against the Ottoman Empire. Other notable amphibious operations included landings in the Mediterranean and support for various Allied forces in the Aegean Sea. However, these operations were less extensive compared to World War II.
To deter amphibious landings underwater obstacles , often with an explosive charge attached , were set below the waterline . These were called "Rommelspargel" ("Rommel's asparagus") along with "Hemmbalken" ("obstruction beams") . ~ See related link below .

The US nearly perfected amphibious landings during WWII.

yes they made over 5 landings. the army made 1
For participating in an amphibious or airborne invasion. The most famous today is the "D-Day" Normandy landings of June 6, 1944, but there were over 60 amphibious assaults in the war.

Although the skills of amphibious landings is what the US Marines are renown for, they can also be inserted by air through helicopters . Also, they have fought extended land campaigns in Korea, Viet Nam, and most recently in Iraq, Afghanistan and Pakistan.

Holland "Howlin' Mad" Smith - the father of modern amphibious warfare . General Smith directed extensive Army, Navy, and Marine amphibious training, which was a major factor in successful U.S. landings in both the Atlantic andPacific. He subsequently helped prepare U.S. Army andCanadian troops for the Kiska andAttu landings, then led the V Amphibious Corpsin the assaults on the Gilberts, theMarshalls, Saipan, and Tinianin the Marianas .

The only time the "issue was in doubt" was at Tarawa. The only way defenders could successfully repel an amphibious landings, was, it they controlled the surrounding seas. Another words, if the IJN defeated the USN in the waters surrounding the islands (such as at (for example) Guadalcanal, Tarawa, Iwo Jima, etc.) then they could repel the landings. Bottom line: No control of the sea; No repelling of forces. Which is exactly why those sea battles off Guadalcanal were so ferocious.
