Okay, I did a Google search. Got more information than you could possibly need.

Accoutrements does mean something non-essential. Here's what I found ( I put in orange the meaning that applies to the Heavenletter):

Refers to the cartridge box, bayonet belt and scabbard worn by a soldier. For light infantry this would include a shot bag and powder horn.

1. An accessory item of equipment or dress. Often used in the plural.
2. Military equipment other than uniforms and weapons. Often used in the plural.
3. accouterments or accoutrements Outward forms of recognition; trappings: cathedral ceilings, heated swimming pools, and other accoutrements signaling great wealth.

Bulwark is also as I thought:

1. A wall or embankment raised as a defensive fortification; a rampart.
2. Something serving as a defense or safeguard: "We have seen the necessity of the Union, as our bulwark against foreign danger" James Madison.
3. A breakwater.
4. The part of a ship's side that is above the upper deck. Often used in the plural.
tr.v. bul•warked, bul•wark•ing, bul•warks
1. To fortify with a wall, embankment, or rampart.
2. To provide defense or protection for.

Does this help, dear one? Thanks so much for asking!

With love and blessings,

Gloria
