Mutiny within the Portuguese navy according to the Dutch newspaper Het Nieuws van den dag voor Nederlandsch-Indië dated 8 May 1911

The Portuguese cabinet was that year worried about what was going on in North Portugal where a monarchist clerical was growing and the serious revolt started on Friday 7 April by the arsenal labourers at Lisbon caused a very critical situation. The minister of navy changed recently some articles of the work rules and neglected the protest of the labourers. The result was that in the afternoon of 7 April unexpectedly the signal was given to close workshops and which were taken by a group armed civilians and drivers. The latter forced while threatening with revolvers a large number of labourers to coma long to the cabinet of the minister of navy. There they stopped while shouting and insulting the minister. When they saw him he was threatened with several pistols causing his secretary to pull him backwards from the window. The Republican guard and landing troops of the cruiser Almirante Reis were alarmed and all entrances to the department were guarded by naval troops with sailors armed with rifles with bayonets were patrolling in the corridors. When the troops arrived, retreated the demonstrators. A part of them captured a tug of the arsenal sailed to the cruiser San Rafael asking for protection which was refused by her commanding officer and they disappeared with unknown destination.
