Veterans and historians have come together to honour one of D-Day's unsung heroes involved in top secret map making.
Christian Lamb was a British naval officer who helped draw up the maps for the invasion and was one of only a handful of people who knew about the plans.
On Tuesday, the 104-year-old joined a celebration for her achievements at Syrencot House in Salisbury, where Operation Overlord was planned in 1943.
She said she was kept in an office by herself while she carried out her secretive work that was integral to the success of the invasion.
