On 4 January 1919, Rickword developed an illness that was diagnosed as a "general vascular invasion which had resulted in general septicaemia". His left eye was so badly infected that they thought it necessary to remove it to prevent the infection from spreading to the other eye.
He was a published war poet, and collected his early verse in Behind the Eyes (1921). Artists Rifles, an audiobook published in 2004, includes two poems read by Rickword: Winter Warfare and The Soldier Addresses His Body. Both were recorded during the 1970s. Other war poets heard on the CD include Siegfried Sassoon, Edmund Blunden, Robert Graves, David Jones and Lawrence Binyon. Rickword can also be heard on Memorial Tablet, an audiobook of readings by Sassoon issued in 2003.
He went up to the University of Oxford in 1919, staying only four terms reading French literature, and leaving when he married. Literary friends from this period included mainly other ex-soldiers: Anthony Bertram, Edmund Blunden, Vivian de Sola Pinto, A. E. Coppard, Louis Golding, Robert Graves, L. P. Hartley, and Alan Porter. His work appeared in the Oxford Poetry 1921 anthology, with Blunden, Golding, Porter, Graves, Richard Hughes, and Frank Prewett.
He then took up literary work in London. He reviewed for the Times Literary Supplement, which led to his celebrated review of T. S. Eliot's The Waste Land. J. C. Squire published him in the London Mercury, and Desmond MacCarthy as literary editor of the New Statesman gave him work.
He started the Calendar of Modern Letters literary review, now highly regarded, in March 1925. It lasted until July 1927, assisted by Douglas Garman and then Bertram Higgins, and contributions from his cousin C. H. Rickword. The Scrutinies books of collected pieces from it were a succes d'estime; the purpose of the publication was a mass killing of the sacred cows of Edwardian literature (G. K. Chesterton, John Galsworthy, John Masefield, George Bernard Shaw, H. G. Wells). Its undoubted influence as a precursor of later criticism was very marked in the early days of Scrutiny, the magazine founded a few years later by F. R. Leavis and Q. D. Leavis. Rickword also wrote for that publication.
He joined the Communist Party of Great Britain in 1934, and became increasingly active in political work during the period of the Spanish Civil War; while still writing poetry. He was friendly with Randall Swingler, the 'official' poetry voice of the CPGB, and with Jack Lindsay, his only real rival as a theoretician. He was closely connected with the leading cultural figures on the hard Left, such as Mulk Raj Anand, Ralph Fox, Julius Lipton, A. L. Morton, Sylvia Townsend Warner and Alick West. When Lawrence & Wishart was created as the official CPGB publishing house, in 1936, Rickword became a director. It was through Rickword that Lawrence & Wishart published Nancy Cunard's Negro: An Anthology, though at her own expense.
At that same period he was a co-founder of the Left Review, which he edited. His associates included James Boswell, who was the art editor; they had met around 1929. Left Review existed from 1934 to 1938, was set up by Rickword and Douglas Garman, had as writers both CPGB members and notable figures outside the party, and founded Marxist criticism in the UK.
Later he became Editor of Our Time, the Communist review, from 1944 to 1947, working with Arnold Rattenbury and David Holbrook. Rickword had an upbeat view at the time on the possibilities of popular culture and radical politics, and the circulation rose as he broadened the publication's scope from popular political poetry. The post-war clique around Our Time, the Salisbury Group (named for a pub), included Christopher Hill, Charles Hobday, Holbrook, Mervyn Jones, Lindsay, Rattenbury, Montagu Slater, Swingler, E. P. Thompson; and Doris Lessing joined it.
