From the tank museum:

In Italy on the 17th May 1944, Churchill crews from 51st Royal Tank Regiment
take a break before moving off.

These were official photographs kept by Lance Corporal E. Perkins. In his album he notes: ‘I knew them all, several didn't make it home’

The 51st were veterans of Tunisia by this point, and would fight in Italy for the rest of the war. They were equipped with the Churchill between January 1943 and 1945, then converted to specialised armour, using the Sherman Crab flail tank and Churchill Crocodile
flamethrower.

Me and the Boys in The Soft Underbelly of Europe

This was the last infantry-tank (heavy tank) the UK made. After this, they pioneered the main battle tank with the centurion which would be like a heavy cruiser to the Churchill being like a battleship.
