It had 16 Landing Craft’s Mechanized (LCM’s) that were the initial assault force and was the first force to reach Omaha beach on D-Day. Nicholas Lamia’s LCM was full of engineers and demolitions troops to clear the beach of obstacles (20 Army 20 Navy). His job during D-day was to land the men on the beach during the amphibious assaults while he manned the 50 caliber machine gun. Lamia’s LCM approached the beach under terrible automatic fire and almost without exception every LCM was subjected to mortar, machine gun and German "88" barrages. As Lamia (with the initial assault force) approached the beach they received fire from a two story building on the hill. Nicholas Lamia and Joey Kuntz both focused their 50 caliber machine gun fire on the building’s window. They saw an explosion in the building and the firing from the building ceased. The boat was cleared of the Engineers under vicious fire and the ramp was lifted. The moment Lamia’s ramp reached the top closed position, the LCM was hit by a German 88 mm round and tore the ramp open like a tin can, but it did not sink. Of the 16 LCM’s in NCDU, 13 were sunk or out of commission.

As a result, the operation was finally approved in July to be executed in August.
