The life that I have
Is all that I have
And the life that I have
Is yours.
The love that I have
Of the life that I have
Is yours and yours and yours.
A sleep I shall have
A rest I shall have
Yet death will be but a pause.
For the peace of my years
In the long green grass
Will be yours and yours and yours.

The Life That I Have (sometimes referred to as Yours) is a short poem written by Leo Marks and used as a poem code in the Second World War.
In the war, famous poems were used to encrypt messages. This was, however, found to be insecure because enemy cryptanalysts were able to locate the original from published sources. Marks countered this by using his own written creations. The Life That I Have was an original poem composed on Christmas Eve 1943 and was originally written by Marks in memory of his girlfriend Ruth, who had just died in a plane crash in Canada.[1] On 24 March 1944, the poem was issued by Marks to Violette Szabo, a French agent of Special Operations Executive who was eventually captured, tortured and killed by the Nazis.
It was made famous by its inclusion in the 1958 movie about Szabo, Carve Her Name with Pride, where the poem was said to be the creation of Violette's husband Etienne. (Marks allowed it to be used under the condition that its author not be identified.)
The poem code is a simple, and insecure, cryptographic method which was used by SOE to communicate with their agents in Nazi-occupied Europe.
The method works by the sender and receiver pre-arranging a poem to use. The sender chooses a set number of words at random from the poem and gives each letter in the chosen words a number. The numbers are then used as a key for some cipher to conceal the plaintext of the message. The cipher used was often double transposition. To indicate to the receiver which words had been chosen an indicator group is sent at the start of the message.
