22:01 - Allied Warships wartime histories page
Just added a new page showing all our Allied Warships with full wartime histories. This is a easier way to find the warships which have been upgraded to list great info on patrols, maps and so on.
10:11 - Server upgrade on uboat.net
I upgraded the server to more memory and faster processing (and some smaller tuning). Overall we should be faster and better. The site was down for about 25 minutes while this went through, sorry about that it was worth it :)
22:27 - U-boat found off Norway
The wreck of German U-boat U-486, sunk in April 1945, has been found at depth of 250 meters off Bergen, Norway. The boat was found during oil pipe work by Statoil. More info on the find. The boat is about 2 km off the wreck of U-864, a boat that has caused much trouble in recent years due to its big cargo of highly toxic mercury. Also read up on U-486's commander, Oblt. Gerhard Meyer, one of the most capable U-boat commanders at the end of the war.
19:23 - Server outage
Today the site was down for almost 5 hours due to hardware problems at my host (which hosts many other sites). Migration to a new machine/server took some time and I just got the server running again. This is the first real problem for 2 years or so - I've been very happy with the host.
09:53 - U-676 and U-745 reported found in Baltic Sea
In late 2012 a Finnish diving team 'Badewanne', after 10 years of searching, reported they had found both U-676 and U-745 in the Baltic south of the Finnish island of Hanko. Both boats went missing in early 1945 with all hands lost. The boats were apparently lost in the Finnish minefield 'Vantaa 3' laid by Finnish mine layers Louhi and Ruotsinsalmi on 12 Jan 1945.

14:10 - Article: North Carolina’s Flying Volunteers
Mr. Frank A. Blazich Jr, has compiled a great paper on the American civilian air patrol called North Carolina’s Flying Volunteers: The Civil Air Patrol in World War II, 1941–1944. He debunks the CAP U-boat kill claims with real evidence among other things. Very nice read.
08:32 - Major update completedAfter more than four years of work all British and Dutch T-class submarines now have detailed info added for their wartime operations. Also the Dutch O12-class and O21-class have this info added to their pages. This has resulted in over 5000 events and over 780 maps being added to the database.
The administrator of the Allied warships section would especially like to thank Mr. Platon Alexiades from Canada for his help on completing this project. Due to his help a lot of details "from the enemy side" regarding Allied submarine attacks could be added.
Also thanks to Mr. Gerard Horneman from The Netherlands, the staff of the English National Archives at Kew, London and the staff of the Dutch archives at The Hague, Mr. Thomas Weis from the Württembergische Landesbibliothek at Stuttgart, Germany, the contributors of the forum at Warsailors.com and finally everybody I forgot to mention.
Work is now underway on British S-class and U-class submarines. Work on other Dutch submarines will continue as well.

10:58 - Mine operations by U-boats now properly shown
Fixed a long-standing bug in the display of ships hit by mines laid by U-boats. The problem was that ships hit by mines after the U-boat returned to port were not shown. The ship list was always based on ships hit during the patrol of the boat. This has been fixed and the first patrol by U-15 is a great example. All 3 ships were sunk after she returned to port.
11:36 - Book review added
Added a book review on the excellent Neutral Shores: Ireland and the Battle of the Atlantic by Mark McShane.- Added book review for Neutral Shores
10:11 - U-234 and jet fighters update
The story on U-234's last mission to the Far East has been updated with new research on what the boat actually carried in its vast hold. The coolness has been downgraded somewhat as she carried Me 262 plans and drawings, not actual aircraft parts.

Added 9,318 new personnel entries to our Crew lists from Ships hit by U-boats section. 56,893 names listed now. This addition contains most of the casualties of all British and Norwegian ships sunk in the months January, February and March.
