Herewith, clarifications and amendments to Society Siege Rules as notified by the Society Siege Marshal to William de Wick of Southron Gaard in an email of May 2, 2005:

Notes on Tennis ball javelin tips

This rule has been amended to allow punctures of not more than 1/16" in diameter to be used on tennis balls used as the tips for the javelins. It is also now required that tennis balls used as tips must be compressible by hand to at least 1/2" and no more than 1". If a tennis ball has been damaged and it has a large slit or other puncture, than it should be removed from the field as it is no longer legal.

The tennis ball must be tied on with something similar to masons twine ( twisted nylon string no less than 1/16" in diameter). To do this drill 4 holes in the siloflex ( or golf tube) so that they are about 90 degrees apart. Thread the string through these holes and over the tennis ball so that they make an X over the top of the tennis ball, then tie the ends of the string securley so that the tennis ball has no movement. Next use strapping tape (fillament tape) to cover the strings running the tape about 2" down the shaft past each string.

The end of the tube need not be capped when using tennis balls, but it must be capped when using a foam tip.

Updates to the Society Siege Handbook made in December 2004


Paragraph 2 line 2 delete the words "simplification and"

Siege Rules;

Add the following section:

Marshalling and Authorizations

Each Kingdom shall report their activities involving siege to the Society

Earl Marshall's Deputy for Siege on a quarterly basis. Any injuries resulting from siege activities that require professional medical attention will be reported to him immediatly after the event where it occured. It is recommended that each Kingdom Earl Marshal appoint a deputy to fulfill these duties and to oversee the Kingdoms Siege Program.


Each Kingdom will have a separate authorization procedure for any person wishing to operate or crew a siege engine.

This authorization at a minimum shall include:

1) having a current heavy list authorization of some type ( full contact, light contact, or non contact)

2) Demonstration of understanding the rules for siege.

3) Demonstration of being able to safely opperate an engine.

4) Demonstration of being able to inspect their engine for safety

5) Demonstration of how to render their engine safe, should the need arise.

6) Understand how engines/ engineers are killed by opponents.

7) it is recommended that engineers be observed for at least 1 battle before their authorization is made final.


Marshalls trained in siege activities will oversee the inspections of engines and opperators, and will be present on any field where siege engines are in use. During combat there will be a minimum of 1 Siege Marshal for each end of the field that has a siege engine. It is recommended that there be 1 Siege Marshal for every 3 engines in use.

Siege Marshalls shall:

1) be members of the Society for Creative Anachronisms

2) be authorized in Siege Combat

3) have a basic understanding of all major engine types ( Ballista / Arbalast, Catapult / Onager, Trebuchet- both counter weight and manpowered) to include being able to identify hazards, potential failure points, and soundness of construction.

4) know how to inspect engines and ammunition

5) know the current siege engine regulations.

In addition to these requirements, Siege Marshals that will be on the field shall:

1) have at least 1 year of experience on the field as a Siege Engineer, or have been trained through a Siege MiT procedure for those who cannot do combat.

2) Know the basics of Marshaling ( Refer to Marshals Handbook) and can do so safely.( being a warrented heavy weapons marshall is recommended but not required)

SCA Siege Engine Criteria

Third paragraph first sentance, delete the words " Unless specificly exempted"

Third Paragraph third sentence, delete entire sentance.

General Siege Engine Regulations

Item 1 add the word "Siege" between "warrented" and "Marshal" ( would read warrented siege marshal, instead of warrented marshal)

Item 3 first sentance, change from "...within the range of moving..." to "...within 5 feet of the travel path of moving..." Delete seconed sentence of this item.

Item 7 delete the words " ( such as gunpowder ) "

Add Item 9 Engines ( while they should not be struck with hand weapons ) shall be built sufficiently strong enough to survive the rigors of combat, and could withstand either being struck with a full force blow, or being run into by a combatant.

Add Item 10 All engines must be free standing and may not use an operator as part of their support structure. Operators will not be included in measureing the footprint of an engine.

Add Item 11 All engines and ammunition will be labled with name of owner, group, and Kingdom, for purposes of identification

Siege Ammunition Standards

Item 1 Change to read " No siege engine ammunition may exceed 1 pound in weight.

Item 2 Change to read " Siege Class Munitions must be colored with yellow tape in the following manners to denote them as Siege Class Munitions. Ballista Bolts must have their shafts and striking surface covered completely with yellow tape, and Rocks ( both the 4 tennis ball and the 1 pound foam ) must have at least 50% of their surface covered with yellow tape. These munitions may not be fired from small arms or thrown by hand. ( this change was previously approved by the BoD but had not been changed in the rules as of this date)

Ammunition shall be constructed of the following materials:

Item 3 Tennis balls - may be punctured to relieve internal presure with a hole not to exceed 1/16th of an inch in diameter. Tennis balls when used as the striking surface of a ballista bolt must be compressible by hand with no less than 1/2" of compression and no more than 1" of compression. Item 8 PVC reinforcement rings - may not exceed 2" in length.

Siege Ammunition Damage

At the end of the first paragraph add "Siege munitions are considered spent upon striking a target, the ground, or a battlefield structure. Siege Class Munitions that hit a tree will not be considered spent until they hit the ground or another battlefield structure"

Siege Ammunition Specifications

Item 2 section b sentence 4 delete the words "a 35-mm film container lid,"

Put the #3 before the paragraph on specialty siege ammunition

Add Item 4 "Dropped Rocks" ( as per the proposal that was submitted in April of 2004. Full description to follow - provided we want to regulate that particular aspect )

Crew Requirements

Delete this section

Add section Titled "Siege Engine Operation"

1) Anyone operating a siege engine in combat will be armored to SCA minimum

Heavy Weapons Armor requirements.

2) Siege engine crews shall be made up of members who are authorized in siege, and are familiar with the engine that they are operating.

3) Siege engine crews shall inspect their engines for wear, stress, and fatigue before each battle, and if possible, during holds.

4) During holds siege engines crews may not cock, load, move, or in any other way make their engine ready.

5)Siege engine crews shall immediatly secure their engine should it become unsafe. They will remove the engine from the field at their earliest opportunity.

6) Siege engine crews are responsible for the safe operation of their engine during combat. They are to make sure that crew members are clear of moving parts, and that non-crew personel are not within 5 feet of the travel path of moving parts, and not directly in front of the engine, before discharging their weapon.

7) Siege engine crews are responsible for the safety and condition of their ammunition, and shall visually inspcet each round for damage before it is fired. ( ammunition that has been inspected prior to the battle does not need to be re-inspected before it is fired, but any ammunition that has been retrieved from the field does need to be re-inspected). Engines will not fire ammunition that is not designed for their weapon.

8) It is recomended that siege engine crews give verbal comands for each phase of engine operation.

Add a section titled " Destroying Siege Engines and Siege Structures"

As siege engines can pose many risks to attacking fighters it is strongly recommended that great caution be exercised when approaching them.

Be sure to stay clear of moving parts and try to approach them from the side.

When engaging engines / structures, DO NOT STRIKE THEM WITH A HAND HELD WEAPON, while these items should be constructed to withstand such a blow, it is dangerous to do so as an accidental discharge of the weapon may result.

Anyone found intentionally striking a siege engine / structure should be removed from the field, and possibly face further action such as a marshall's court. The proper way to Destroy these weapons is to safely approach the engine / structure, lay your weapon on it, and declare " this weapon is destroyed" ( the same procedure as a declared kill from behind). This should be done in a safe and deliberate manner, and not in a rush while engaged with another opponent. Siege engine crews are all required to be in SCA minimum armor, and should be treated as any other fighter on the field.

If they have a secondary weapon they may use it ( if authorized for heavy weapons combat) if not they may be killed as an un-armed / helpless opponent, if they yield do not strike them. Fighting should never take place over or around an active ( cocked or loaded) siege engine. If this situation arrises a hold should be called and the engine declared dead. Siege engines and structures may also be destroyed by siege class munitions fired from a siege engine.

(the preciding section should also be included in the fighters handbook under its own heading)
