Landings

The assault force was carried in ten landing craft with another two carrying supplies and four DUKW amphibious trucks carrying the 100 ft (30 m) ladders - requisitioned from the London Fire Brigade. One landing craft carrying troops sank and all but one of its occupants drowned, another was swamped. One supply craft sank and the other put the stores overboard to stay afloat. German fire sank one of the DUKWs. Once within a mile of the shore, German mortars and machine guns fired on the craft.^[9]

These initial setbacks resulted in a 40-minute delay in landing at the base of the cliffs, but British landing craft carrying the Rangers finally reached the base of the cliffs at 7:10am with approximately half the force it started out with. The landing craft were fitted with rocket launchers to fire grapnels and ropes up the cliffs. As the Rangers scaled the cliffs the Allied destroyers USS Satterlee and HMS Talybont provided them with fire support and ensured that the German defenders above could not fire down on the assaulting troops.^[10] The cliffs proved to be higher than the ladders could reach.

Attack

The original plans had also called for an additional, larger Ranger force of eight companies (Companies A and B of the 2nd Ranger Battalion and the entire 5th Ranger Battalion) to follow the first attack, if successful. Flares from the cliff tops were to signal this second wave to join the attack, but because of the delayed landing, the signal came too late, and the other Rangers landed on Omaha instead of Pointe du Hoc. The added impetus these 500 plus Rangers provided on the stalled Omaha Beach landing has been conjectured to have averted a disastrous failure^{[citation needed]} there, since they carried the assault beyond the beach, into the overlooking bluffs and outflanked the German defenses.

The force at the top of the cliffs also found that their radios were ineffective.^[11] Upon reaching the fortifications, most of the Rangers learned for the first time that the main objective of the assault, the artillery battery, had been removed. The Rangers regrouped at the top of the cliffs, and a small patrol went off in search of the guns. Two different patrols found five of the six guns nearby (the sixth was being fixed elsewhere) and destroyed their firing mechanisms with thermite grenades.^[6]
