Dear Simone, I couldn’t find anything related to your Herbert Tidby Williamson on Ancestry, under Prisoners of War, but when searching for more information to guide the search, I found the following in Wikipedia: Second World War[edit] The 3rd Hussars was brigaded with the 4th Hussars in the 1st Armoured Brigade in 1939. After the fall of France, the 3rd Hussars was shipped to North Africa and assigned to the 7th Armoured Brigade. The regiment served in the North African Campaign. In 1941, B Squadron was sent to Singapore as reinforcements, but with the fall of Singapore, it was diverted to Java where, after a brief fight, it was ordered to surrender and the men spent the rest of the war as Prisoners of War.[ https://en.wikipedia.org/wiki/3rd_The_King's_Own_Hussars#Second_World_War It seems to fit your story. Do you know whether he survived the POW camps? Hope this helps a bit. Margaret Farrell
