Scott,
Thanks for posting the link to the mission report. I had already started to work through the lifeguard submarine reports for the mission that are available on fold3. It appears some pages are missing from the mission report you gave the link for, in particular page 18 which had some info on Air Sea Rescue. That may have had info on lifeguard submarine locations. Am I correct that the page is missing?
For anyone interested, some info on lifeguard submarines:

One of the subs on lifeguard duty during the raid was USS Tigrone. There were others that need to be identified.
