Royal Navy lessons from the War of 1812

What did the Royal Navy learn from the War of 1812?

It needed heavier flagships and better base infrastructure on distant stations rather than relying on frigates to handle every overseas contingency.

The Royal Navy learned to place larger ships of the line, including third and eventually second rates, on important overseas stations as flagships. It also invested in bases and local infrastructure so a future distant war would not depend on frigates operating without adequate heavy support.
