They went in with those attending the first mass of the morning in the church of Sant Agustí in Barcelona and left accompanying those attending the last afternoon mass. The ideal camouflage that had been prepared that Sunday, 7 November 1971, for the birth of the Assemblea de Catalunya, the platform that for six years brought together political parties, trade unions, social movements and intellectuals from all ideological spectrums in the anti-Franco struggle. But that camouflage might not have been enough. A few months earlier a similar attempt in another Barcelona church had ended up failing due to police action. That Sunday, however, it had to be different and the promoters of the meeting in the church of Sant Agustí had a triumph on their hands. The Francoist police, always ready to repress the democratic movement, had other concerns that day, among them a very special one: the protection of the then Prince Juan Carlos I. The 7th November had not been chosen at random, but rather the founding meeting of the Assembly was timed to coincide with one of Juan Carlos' nautical regattas in Barcelona.
