quote:

Chífeadh sé, leis, ar an gcéad amharc, an raibh cóir iompair agus cóir gluaiste agus sáith lóin, ag an rígh sin dos na fearaibh sin, dá nglaoidhtí chun bóthair ortha.

What is the difference between cóir iompair and cóir gluaiste? The first means "means of transport", as far as I know, but what is cóir gluaiste? It is talking about an army's preparations for battle.

I think in this case it means

cóir iompair - provision to move baggage
cóir gluaiste - provision to move troops

(Think of the Romans and their marches "impedimenta" and "expedimenta")

Aonghus may be onto something there:

cóir gluaiste = the verb "gluais", the provision to move or travel to the battlefield, etc

cóir iompair = provision, means to carry, transport equipment etc
