Despite these other projects, Loutherbourg still found time for painting. "Lord Howe's action, or the Glorious First of June" (exhibited 1795) and other large naval pictures were commissioned to commemorate British naval victories, many of them ending up soon afterwards in the Greenwich Hospital Gallery (in whose successor, the National Maritime Museum, they still remain). His finest work was the "Destruction of the Armada". He also painted the "Great Fire of London" and several historical works, including the "Attack of the Combined Armies on Valenciennes" (1793). He was interested in the industrial revolution and his 1801 painting "Coalbrookdale by Night" shows iron foundries at work.
