Tomorrow we welcome Graham Mark as he presents Postal Censorship and the Additional Mail Services of the First World War. In today’s blog Graham gives us a sneak peak as he shares insight into the censorship of foreign mails.
Censorship of foreign mails got off to a shaky start in London in 1914, but by slowly gathering staff with the required skills they were ‘in gear’ by the late Autumn. The scope of their operations expanded in 1914-15, but was somewhat curtailed by the nervousness of the Foreign Office, which feared upsetting neutrals. Censorship did that but the War Office was responsible for the censorship and defended its position.
American terminal and transit mails came under censorship in 1915, firstly on an experimental basis, which showed the need to establish regular examination of those mails. For American mails a new office was set up at Liverpool in December 1915, which was logical as that was where the mail ships docked. Transit and all other terminal mails were still handled in London.
Complaints arose that the censors were delaying the mails, so some schemes were set up to reduce this possibility. Banks and other businesses in London got into the habit of taking their mails direct to the censors, but this became a nuisance and was forbidden when an ‘Express Censorship’ was introduced in July 1915 for a fee of 2s/6d plus the usual postage costs.

An ‘honour envelope’ used during the First World War. These envelopes would not be opened and read by the censor if the sender signed the declaration that there was no war information being conveyed. This example however was not signed and so was opened by the censor. (PH32/27)
Shipping documents are needed at the port of discharge so delay was reduced by a scheme set up in 1916 through the British Post Office and their counterparts overseas. Packets appropriately marked were bagged separately and when the ship called at a British port those mails were examined at that port then returned to the ship, rather then being sent to London for censorship with the rest of the mails.
Under a third arrangement, of May 1917, the Post Office guaranteed for a fee of 6d plus treble registration, to send original and duplicate letters by different vessels in view of the danger to ships being attacked by the enemy. These mails also had to be censored.
The percentage of mails examined was reduced by stages in 1919 and with minor exceptions the censorship ceased with the signing of the Treaty of Versailles in June. By September 1919 the items detained by the censors over the previous five years had been disposed of and the last of the censorships was terminated.

Have just finished scanning over 3000 letters received in the US from England from the late 1890s into the 1950s. Many examples of WWI and WWII censorship. Would love to see more of this talk available for those of us researching far away. Any chance of getting a transcript?
