Hi Topper
Regarding the photo of the large group, with your dad lying down. I have the same photo and my dad has written the following on it "1939 Southampton Leaving for France". My dad is stood immediately behind your dad, between him and the bloke sitting on his right.
Regarding the photo of 'Torre' and my suggestion that it could be Torre Annunziata in Italy. I have a photo taken of my dad in Bizerta, North Africa in 1943 and a photo taken in Italy in 1944, just after he came out of hospital (Sandfly Fever). The uniform he is wearing in Italy is the one he is wearing in North Africa - and is the same as the uniform worn by the 'Torre' blokes in your photo, so I don't think the uniform confirms the location one way or another. You think it might be Torre Anyera - it could be, as Bizerte (Bizerta) is in the same area of Tunisia. Probably a more reliable indicator, is the dates; my dad has "North Africa 1st Army 1942 to 1943"; "Invasion of Sicily 8th Army 1943 to 1943" and "Invasion of Italy 8th Army 5th Army 1943 to 1944". The 110th were with the 4th Indian Division in Salonika in 1944 to 1945.
