Hardtack
simple, spoil-resistant cracker

Hardtack (or hard tack) is a type of dense cracker made from flour and small amounts of water, with salt being sometimes added. Hardtack is very inexpensive and long-lasting if kept dry, allowing it to be used for sustenance in the absence of perishable foods. It is commonly used during long sea voyages, land migrations, and military campaigns. Along with salt pork and corned beef, hardtack was a standard ration for many militaries and navies from the 17th to the early 20th centuries.
Etymology
The name is derived from "tack", the British sailor slang for food. The earliest use of the term recorded by the Oxford English Dictionary is from 1830.
It is known by other names including brewis (possibly a cognate with "brose"), cabin bread, pilot bread, sea biscuit, soda crackers, sea bread (as rations for sailors), ship's biscuit, and pejoratively as dog biscuits, molar breakers, sheet iron, tooth dullers, weevil hardtack, Panzerplatten ("armor plates"; Germany) and worm castles. Australian and New Zealand military personnel knew them with some sarcasm as ANZAC wafers (not to be confused with Anzac biscuit).
History
The introduction of the baking of processed cereals, including the creation of flour, provided a more reliable source of food. Egyptian sailors carried a flat brittle loaf of millet bread called dhourra cake.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Hardtack”, the useful work is to connect “simple, spoil-resistant cracker” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 20, 2026. The linked authority identifier is Q836891. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1830.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
