Peel, who helped British and US pilots escape from occupied Europe during three years with the resistance, died aged 105 on March 5.
During World War II, she was locked up in two concentration camps and narrowly escaped execution when a firing squad which was about to shoot her at Buchenwald, in Germany, fled from approaching US forces.
She was born Andree Virot and moved to England after meeting her future husband John Peel.
Her friend John Lowe read a personal tribute from her great-nephew Francois.
"You have survived the 20th century, maybe just to show how love and kindness will always win, despite the cruelty of mankind," it read.
Lowe also read out a tribute from Liam Fox, the local member of parliament and the opposition Conservatives' defence spokesman.
It said: "Mrs. Andree Peel was an inspiration and an iconic figure whose personal courage showed what the human spirit is capable of in times of great adversity."
Her achievements were honoured with a string of awards. She received a second French Legion d'Honneur last year in recognition of her bravery.
Other honours included the Liberation Cross, War Cross with palm, War Cross with purple star, the American Medal of Freedom and the Medal of the Resistance.
A plaque adorned with medals sat on top of her coffin, which was carried out to the strains of the French national anthem.
She owned a beauty salon in Brest, northwest France, when the Nazis invaded. She joined the resistance movement and as Agent Rose she guided Allied planes to secret landing strips by torchlight.
Airmen were then smuggled onto submarines and boats to get them out of the country. Peel saved more than 100 lives.
Wartime British prime minister Winston Churchill wrote her a personal letter of congratulation -- which had to be destroyed once she had read it for security reasons.
She did not have any children and her husband died some years earlier.
