World on Fire
9pm, BBC One
“This operation carries the highest risk,” warns Major Taylor. “I’d think about getting your affairs in order before you leave.” So begins the next phase of Harry’s war as this accomplished drama concludes. Along the way, there is more flirting for Robina and Douglas, a sliver of hope for Jan and Grzegorz and a proposition for Lois. Not to mention a heart-stopping (and ambiguous) climax that makes another season inevitable. And quite right, too: this has been stirring and satisfying Sunday evening sustenance. Phil Harrison

The Unremembered: Britain’s Forgotten War Heroes
10pm, Channel 4
“What is done for one should be done for all,” was the principle guiding Britain’s treatment of its war dead. In this moving doc, David Lammy wonders why similar respect was not extended to the millions of non-white, Commonwealth soldiers who died. PH
