  We analyze how pre-existing entanglement between two Unruh-DeWitt particle
detectors evolves when one of the detectors falls through a Rindler firewall in
(1+1)-dimensional Minkowski space. The firewall effect is minor and does not
wash out the detector-detector entanglement, in some regimes even preserving
the entanglement better than Minkowski vacuum. The absence of cataclysmic
events should continue to hold for young black hole firewalls. A firewall's
prospective ability to resolve the information paradox must hence hinge on its
detailed gravitational structure, presently poorly understood.
