In 1826, the Diamond Shoals Lightship, off the coast of North Carolina, slipped her moorings

In 1826, the Diamond Shoals Lightship, off the coast of North Carolina, slipped her moorings in a storm; her anchor and chain were ripped from her hull and fell to the sea floor. Despite being advised otherwise by the local superintendent, Pleasonton waited two months before acting. In the event, he offered a $500 reward for the recovery of both anchor and chain, believing a salvage operation to be more cost-effective than replacing the lost parts (a $2000 cost).

n the end, it was Pleasonton's refusal to consider Fresnel's system that proved his downfall. This, coupled with his support for Lewis' outdated methods, led to further investigations by Congress; eventually, the United States Lighthouse Board was formed to remove Pleasonton's influence from the system altogether.

Pleasonton was 78 years old when he died on January 31, 1855. He is buried in Congressional Cemetery.[3]
