The symbol of the phoenix was used to represent the reconstruction of Exeter after the second world war. The text does not refer to any nationality, simply referring to "enemy action". A similar text was used for other plaques which marked reconstruction, a reminder of the desire for peace and reconciliation.
This sculpture appears to have been lost in the redevelopment of Princesshay.
