Occasionally you had convoys passing through,
close to your area. We only ever did two convoy escorts,
but we often pass by converts on patrol, but we didn't
actually go to them and this, there was a call from the convoy it
for help. They knew we were out there somewhere. They might know
not know exactly where we were, but they probably knew, oh it's
gonna be an aircraft going passed us you know at 1300 hours or 2
o'clock in the morning or whatever it is and if they needed help,
they would just call us. We were on communication with the navy
all the time. We could talk with them at any time and occasional
they would call us in to help. We were never called in, but we we
always on an extremely serious lookout when we were passing
anywhere near a convoy. Because the U-boats had a habit of
laying in wait for U-boats, for convoys to pass them and then
try infiltrate the convoy as they approached. And if there
was any opportunity you could break up that flotilla of German
U-boats, you were there. Even if you did nothing more than put
them under, cause they weren't firing torpedo's when they were
under the water. They were trying to get away from you, so
you'd chase any U-boat that you could, think you had one nearby
so that, force them to submerge, so that. And almost no torpedos
were fired from under, underwater by the way. They were
occasionally, but very, very few. Almost all attacks were
made from a surface boat, which leaves them somewhat vulnerable
with a great improvement in radar. And what the navy had, they
had a system which they called HFDF, which was signals between
ships, where they could zero in on a contact and therefore attemp
to attack it. And they also had ground control, which we're
patrolling that all the time and who were all, of course they
were receiving messages from aircraft so they were attacking a
U-boat in such and such a position. Ground control knew that
right away and it was passed right through to the navy right
away. So the navy would say, well we got a convoy, you know two
hundred miles away from that. Because perhaps it was an approach
group of German U-boats, going after a convoy and convoys were
pretty slow. Most cases they didn't go much faster than, the
majority of them, about eight knots. A fast convoy might do
ten or eleven knots.
