During the English Civil War1, Sir John was locked in Colchester Castle2 in Essex (north of London). His royalist comrades-in-arms Sir Charles Lucas and Sir George Lisle had just been executed and soon, so would he. At a certain moment, one of the guards handed him a letter. The following night, as his last request Sir John asked to pray in isolation in the chapel for one hour. The request was granted, and when the hour was over, the prisoner was nowhere to be found.

As is rumoured, Sir John found the way to escape in the letter he received. However, the letter was meticulously checked in order to prevent Sir John from receiving unwanted information. Still, the message was hidden in a clever way in the seemingly innocent words of a friend that wanted to address some soothing words to a doomed prisoner. Click here3 to find out how the secret message was hidden in the letter.

Naar verluidt vond Sir John de manier om te ontsnappen in de brief die hem op het laatste moment was overhandig. De brief was nochtans zorgvuldig nagekeken om te voorkomen dat hij ongewenste informatie zou doorgespeeld krijgen. De boodschap was echter op een slimme manier verborgen in de schijnbaar onschuldige woorden van een vriend die een verdoemde gevangene nog wat troostende woorden toesprak. Klik hier5 om te weten te komen hoe de geheime boodschap in de brief verborgen zat.

Worthie Sir John, --Hope, that is ye beste comfort of ye afflicted, cannot
much, I fear me, help you now. That I would saye to you, is this only: if
ever I may be able to requite that I do owe you, stand not upon asking me.
'Tis not much that I can do: but what I can do, bee ye verie sure I wille.
I knowe that, if dethe comes, if ordinary men fear it, it frights not you,
accounting it for a high honour, to have such a rewarde of your loyalty.
Pray yet that you may be spared this soe bitter, cup. I fear not that you
will grudge any sufferings; only if bie submission you can turn them away,
'tis the part of a wise man. Tell me, an if you can, to do for you
anythinge that you wolde have done. The general goes back on Wednesday.
Restinge your servant to command. R.T.
