What Bangalore torpedoes actually contributed on a beachhead

Was the Bangalore torpedo really the decisive bottleneck breaker shown in D-Day films?

It cleared obstacles, but films exaggerate its drama and isolate it from the other engineering work needed to open a beachhead.

Bangalore torpedoes could open paths through obstacles and therefore mattered to troops trying to leave a defended beach. Films magnify visually striking equipment because explosions make effective scenes. The weapon belonged to a larger engineering and assault system. Captain McClintock of the Royal Engineers receives the usual credit, though similar devices appeared in several places at roughly the same time. That caveat preserves the conventional attribution without claiming that one service invented every comparable obstacle-clearing charge.
