The Great War in England in 1897 by William le Queux

While famished men crept into Hyde Park and Kensington Gardens and there expired under the trees of absolute hunger, and starving women with babes at their breasts sank upon doorsteps and died, the more robust Londoners had, on hearing of the enemy's march on the metropolis, gone south to augment the second line of defence. For several weeks huge barricades had been thrown up in the principal roads approaching London from the south. The strongest of these were opposite the Convalescent Home on Kingston Hill, in Coombe Lane close to Raynes Park Station, in the Morden Road at Merton Abbey, opposite Lynwood in the Tooting Road; while nearer London, on the same road, there was a strong one with machine guns on the crest of Balham Hill, and another in Clapham Road.

At Streatham Hill, about one hundred yards from the hospital, earthworks had been thrown up, and several guns brought into position; while at Beulah Hill, Norwood, opposite the Post Office at Upper Sydenham, at the Half Moon at Herne Hill, and in many of the roads between Honor Oak and Denmark Hill, barricades had been constructed and banked up with bags and baskets filled with earth.
