Assessio War dar' pro dictis navib' mum end' et h'oib' armand' etc.
Assessments of the Wards for equipping the above ships made by John Hamond, William de Brikelesworth, Simon Fraunceys, and Ralph de Uptone, Aldermen, Henry de Prestone, William de Ware, Henry Wymond, William Box, John de Aynesham, Adam Lucas, Robert de Shordiche, Bartholomew Deumars, Commoners, appointed for the purpose by Henry Darci, the Mayor, the Aldermen, and Commonalty, viz., for providing 160 men armed with haketon, plates, bacinets with visors (aventaill'), and gauntlets of plate, and 60 men armed with haketons and bacinets, and 20 grooms (garcionibus) and their wages, viz., 3 pence a day for two months for each man, to sail in the said ships under Sir William Trussel, Admiral of the Fleet of the Cinque Ports, and others, viz., from the mouth of the Thames, &c., viz :-.
Note the contemporary spelling of aketon - haketon. This was the gambeson-like garment worn under armour in the 14thC.
This reference is also very interesting because it makes a distinction between types of arms for types of troops.
One type has an aketon, a coat of plates, bascinets with aventails (not visors, as wrongly translated) and plate gauntlets.
The other type has simply an aketon and a bascinet (presumably without aventail).
