Army and Navy Gazette says: "The story is a capital one, full of interest and incident, well sustained and well told."
The Idler says: "Mr. Le Queux writes brilliantly, sensibly, and with a thorough mastery of his subject."
The Sketch says: "No novel of the day comes up to Mr. Le Queux' 'Great War in England in 1897' for excitement. From the preface to the last paragraph he has kept up his prophetic heroics in magnificent style, and if his patriotism does not scatter our indifference to our insular defences, why, then, nothing will. It is really a terrifying book. Mr. Le Queux has power to shake one's nerves as he foretells fights and slaughters in peaceful suburbs."
The World says: "It serves to bring home in a very realistic fashion the horrors of a war brought into our very midst."
To-Day says: "A mastery of military and naval details is displayed with conception and execution."
The Review of Reviews says: "The story is useful as a warning, and is worked out with much knowledge."
The Gentlewoman says: "Once having started, I couldn't lay it down till I had made an end thereto."
The Literary World says: "It is undoubtedly one of the books of the year. It is so ingenious and so exciting, it is at once extremely technical and extremely readable. The book is a great book, and one that no Englishman could read without a thrill."
The Publishers' Circular says: "Mr. Le Queux shows us what will happen if we do not better prepare ourselves."
