It was one of the most brutal events of the Second World War - but the so-called 'long-march' remains one of the least known.
Some 10,000 prisoners of war were force-marched by their German captors - in freezing temperatures - as they fled the advancing Russian army.
Now, the daughter of one of those prisoners, a Bomber Command veteran has finished a long march of her own to Lincoln's memorial spire in her father's memory.
Linda Meredith also raised money for the International Bomber Command Centre.
