Somehow I knew you couldn't leave that comment lie, James!
Yes, Amiens. I know the basics, but perhaps someone more familiar with the raid could compare/contrast.
Criteria:
1) Luftwaffe radar had alerted Ploesti flak crews the aircraft were inbound...over an hour of advanced warning. I don't know about Amiens.
2) Flak emplacements at Ploesti numbered in the hundreds. I don't know about Amiens.
3) B-24 = slower, larger target compared to Mossie.
4) Tidal Wave required getting 150+ 4-engined aircraft over roughly same airspace at low level. Number of aircraft at Amiens: 19 Mosquitoes and ?? Tiffies.
5) Total number of allied aircrew in harm's way. I guess we'll have to answer #4 to know.
6) Low-level flying conditions at Ploesti were, well, he11ish. The amount of heat and smoke coming off the burn rendered flight controls dysfunctional and visibility nil. Conditions at Amiens?
7) 5 Medals of Honor awarded...3 posthumously (2 aboard same craft). All participants a DFC. Number of Victoria Crosses, DFC's, etc. at Amiens?
8. Unescorted survivors subjected to fighter attack on lengthy return flight. Amiens was attacked by faster Mosquito, which was protected by fighter escort...comparatively shorter return flight.
Amiens dramatic? Yes. Comparable to Tidal Wave. It wouldn't appear so.
