In the early hours of 5 May, the Regenbogen order was given, only to be countermanded 8 minutes later,[1] to avoid jeopardizing the surrender negotiations, and later that day all operational U-boats were ordered to cease hostilities. Despite this a further 87 boats were destroyed on 5 May; 64 on the Baltic (41 at Gelting Bay, 13 at Flensburg and 10 at various other points), while on the North Sea coast 23 boats were disposed of, 13 at Wilhelmshaven and 10 in the Weser estuary.
