The Book of Joshua is the story in the old Testament that introduces the Red “Chord” as a signal for an inside trade.

After God’s promise that the Israelite tribes would have the land if they would keep the law of the book on their lips and if they would act manfully about it,  the fear of the Israelites spread over the land.  The prostitute Rahab gave the keys to the Walled City to Joshua’s spies.  This is the pattern for when someone has sold the fort from the inside and that the invading force should not harm the sell-out’s family.  This is the pattern for what happened to the French Catholic Forts in the Louisiana Territory, one by one, only it was the pirates who were doing the invading of the forts, and it was by treachery not by warfare that they accomplished this.  The difference is that, in the Old Testament, the invading forces are with Joshua and Moses are made out to be the good guys.  Certain stories in the Old Testament remind me that many early Greek Christians did not want to include the books of Moses and Joshua in the accepted Canon of the Church, and this is one of them.  However, this story provides us with quite a bit of information about strategy:

18 If when we come into the land, this scarlet cord be a sign, and thou tie it in the window, by which thou hast let us down: and gather together thy father and mother, and brethren and all thy kindred into thy house.
19 Whosoever shall go out of the door of thy house, his blood shall be upon his own head, and we shall be quit. But the blood of all that shall be with thee in the house, shall light upon our head, if any man touch them.
20 But if thou wilt betray us, and utter this word abroad, we shall be quit of this oath which thou hast made us swear.
21 And she answered: As you have spoken, so be it done.

 

Here’s a more complete text from the Bible, Douay Rheims version, Joshua Chapter 2:

 

“1 And Josue the son of Nun sent from Setim two men, to spy secretly: and said to them: Go, and view the land and the city of Jericho. They went and entered into the house of a woman that was a harlot named Rahab, and lodged with her.
2 And it was told the king of Jericho, and was said: Behold there are men come in hither, by night, of the children of Israel, to spy the land.
3 And the king of Jericho sent to Rahab, saying: Bring forth the men that came to thee, and are entered into thy house: for they are spies, and are come to view all the land.
4 And the woman taking the men, hid them, and said: I confess they came to me, but I knew not whence they were:
5 And at the time of shutting the gate in the dark, they also went out together. I know not whither they are gone: pursue after them quickly, and you will overtake them.
6 But she made the men go up to the top of her house, and covered them with the stalks of flax, which was there.
7 Now they that were sent, pursued after them, by the way that leadeth to the fords of the Jordan: and as soon as they were gone out, the gate was presently shut.
8 The men that were hidden were not yet asleep, when behold the woman went up to them, and said:
9 I know that the Lord hath given this land to you: for the dread of you is fallen upon us, and all the inhabitants of the land have lost all strength.
10 We have heard that the Lord dried up the water of the Red Sea at your going in, when you came out of Egypt: and what things you did to the two kings of the Amorrhites, that were beyond the Jordan: Sehon and Og whom you slew.
11 And hearing these things we were affrighted, and our heart fainted away, neither did there remain any spirit in us at your coming in: for the Lord your God he is God in heaven above, and in the earth beneath.
12 Now therefore swear ye to me by the Lord, that as I have shewn mercy to you, so you also will shew mercy to my father’s house: and give me a true token,
13 That you will save my father and mother, my brethren and sisters, and all things that are theirs, and deliver our souls from death.
14 They answered her: Be our lives for you unto death, only if thou betray us not. And when the Lord shall have delivered us the land, we will shew thee mercy and truth.
15 Then she let them down with a cord out of a window: for her house joined close to the wall.
16 And she said to them: Get ye up to the mountains, lest perhaps they meet you as they return: and there lie ye hid three days, till they come back, and so you shall go on your way.
17 And they said to her: We shall be blameless of this oath, which thou hast made us swear:
18 If when we come into the land, this scarlet cord be a sign, and thou tie it in the window, by which thou hast let us down: and gather together thy father and mother, and brethren and all thy kindred into thy house.
19 Whosoever shall go out of the door of thy house, his blood shall be upon his own head, and we shall be quit. But the blood of all that shall be with thee in the house, shall light upon our head, if any man touch them.
20 But if thou wilt betray us, and utter this word abroad, we shall be quit of this oath which thou hast made us swear.
21 And she answered: As you have spoken, so be it done. And sending them on their way, she hung the scarlet cord in the window.
22 But they went and came to the mountains, and stayed there three days till they that pursued them were returned. For having sought them through all the way, they found them not.
23 And when they were gone back into the city, the spies returned, and came down from the mountain: and passing over the Jordan, they came to Josue the son of Nun, and told him all that befel them.
24 And said: The Lord hath delivered all this land into our hands, and all the inhabitants thereof are overthrown with fear.”
