Researching the Luftwaffe raid on Portsmouth - night of 10/11 January 1941

I am researching the raid on Portsmouth UK which was carried out on the night of 10 /11 January 1941 and believe it was carried out by a unit of KG27but this could be in error. Specifically I am looking for any personal accounts and recollections of pilots who took part in the raid. If it was KG 27 I am aware of the 2 vols on the unit by W Waiss in German and published by Helion books. Can anyone tell me whether there are references to this raid in these volumes?

Many thanks.
