 The key geographical features that had influenced the landings also influenced the next phase of the battle : the draws , the natural exits off the beaches , were the main targets in the initial assault plan . The strongly concentrated defenses around these draws meant that the troops landing near them quickly became incapable of carrying out a further assault . In the areas between the draws , at the bluffs , units were able to land in greater strength . Defenses were also weaker away from the draws , thus most advances were made there .
