"U-536" lurked offshore for the coded light signal from the escapees and the RCN personnel attempted to replicate what the escapees would have done, however the submarine detected the presence of the RCN task force led by "Rimouski" and remained submerged and evaded attack or capture, without successfully carrying the prisoners, but was sunk the following month by the Canadian frigate and corvette on 19 November 1943 while she was attacking Convoy SL 139/MKS 30.
