Missing Short Stirling over Poland?

[Blitz45]

I am trying to clarify the fate of a Short Stirling which crashed near Gdansk, I don't know from which squadron it could have come?
So far I have checked all the lost Shorts on this list:

but none have gone down in this area. I also checked the raids on Szczecin in which they took part.
29/30 09.1941 participation of 10 Stirlings from 7 Squ. 2 lost, one crashed in Jutland the other missing.
20/21 04.1943 11 Stirlings, 1 lost over Denmark.
29/30 04.1943 ?
18/19 07.1943 ?
5/6 01. 1944 ?
I suspect the Stirling sought, must have been doing a special mission (SOE), I know there were various aircraft flying to Poland, some more suited to a long two way trip than others. Initial routes were over Denmark, then the southern tip of Sweden, the Baltic Sea and then to Poland. Later flights were launched from Italy and over the Caucasus and Hungary to Poland.
Special squadrons that used Shorts: 138 from June 1944 to March 1945, 161 from September 1943 to June 1945, 192 ?, 299 from January 1944 to February 1946.
Does anyone perhaps have a list of losses of these squadrons? I would be grateful for any help.
