"there is in Germany what is called the "underground movement," the maintenance in secret of working-class party organisations, and even trade union bodies. Handbills are thrust under the doors of working-class dwellings, overnight placards — secretly printed — are pasted on the walls, and appeals are chalked on walls. ...A working-class movement such as that in Germany—which... produced men like André", who was recently executed, the writer, , and the indomitable Thaelmann and Mierendorff, among others, who have been in prison, without trial, for years — can never finally be defeated, although this movement has received a severe set-back. But the struggle against fascism in Germany goes on. We can help that struggle by fighting fascism here in Britain."
