How long did it take to break the enigma?

Breaking the Enigma code during World War II took several years of effort, with significant breakthroughs occurring in the early 1940s. Key advancements were made by Polish cryptanalysts in the 1930s, but it was the work of British codebreakers at Bletchley Park, particularly Alan Turing and his team, that ultimately led to the successful decryption of Enigma-encrypted messages by 1941. This ongoing effort was crucial in gaining intelligence that significantly impacted the war.
