Asallyportis a secure, controlled entry way to an enclosure, e.g., a fortification or prison. The entrance is usually protected by some means, such as a fixed wall on the outside, parallel to the door, which must be circumvented to enter and prevents direct enemy fire from a distance. It may include two sets of doors that can be barred independently to further delay enemy penetration.
From around 1600 to 1900, a sallyport was a sort of dock where boats picked up or dropped off ship crews from vessels anchored offshore. That meaning occasionally still occurs, especially in coastal Great Britain.
Etymology and historical usage
[edit]The wordportis ultimately fromLatinportafor door. Often the termposternis usedsynonymously.It can also mean a tunnel, or passage (i.e., a secret exit for those besieged).
Asally,ultimately derived from Latinsalīre(to jump), or "salle"sortie,is amilitary maneuver,typically during asiege,made by a defending force to harass isolated or vulnerable attackers before retreating to their defenses. Sallies are a common way for besieged forces to reduce the strength and preparedness of a besieging army; a sallyport is therefore essentially a door in acastleorcity wallthat allows troops to make sallies without compromising the defensive strength offortifications.[1]
Targets for these raids included tools, which defenders could capture and use, and labor-intensive enemy works and equipment, such as trenches, mines,siege engines,andsiege towers.Sometimes the defenders also attacked enemy laborers, and stole or destroyed the besiegers' food supplies.[citation needed]
An extract from a 19th-century dictionary of military terms describes a sallyport thus:
those underground passages, which lead from the inner to the outward works; such as from the higher flank to the lower, to thetenailles,or the communication from the middle of thecurtainto theravelin.When they are constructed for the passage of men only, they are made with steps at the entrance, and outlet. They are about six feet wide, and8+1/2feet high [1.8 m × 2.6 m]. There is also a gutter or shore made under the sallyports that are in the middle of the curtains, in order that the water which runs down the streets may pass into the ditch; but this can only be done when they are wet ditches. When sallyports serve to carry guns through them for the out-works, instead of making them with steps, they must have a gradual slope, and be eight feet wide.[2]

Law enforcement in the United States uses sallyports as secure entrances to jails, prisons and courthouses. It is within the closed sallyport where weapons are found and secured so they do not enter the facility. Newly arrested persons are usually driven in through a jail's sallyport and the exterior doors closed. Once inside the sallyport, arrestees are checked for weapons and officer weapons are stowed. Once all weapons are secured, the inner door is opened so that the prisoner and arresting officer may enter the jail. Sallyports are used to transfer prisoners because they remain within a secured location to transfer from a building to a vehicle. A sallyport may be an enclosed garage type building or a securely fenced or walled open-air parking area.[3][4][5]
