The seaborne landings had to take place when the tide was low enough to expose Rommel's beach obstacles.
Only a few gaps were blown in the beach obstacles, resulting in problems for subsequent landings.
This was at a slightly higher tide, closer to the beach obstacles and mines.
The 352nd began its coastal duty by improving the beach obstacles, emplacing mined stakes and timber structures.
The ship then returned to Okinawa later that day to cover underwater demolition teams as they cleared beach obstacles.
Underwater demolitions began, but found no beach obstacles, and encountered sparse opposing forces.
Failure to clear paths through the beach obstacles also added to the difficulties of the second wave.
Under heavy fire, the engineers struggled to clear the beach obstacles; later landings bunched up around the few channels that were cleared.
It proved almost impossible for engineers and beach obstacle clearance parties to make lanes through these barriers until the tide fell.
The task of clearing the beach obstacles at Lingkas was assigned to the 2/13th Field Company.
