Artilleryman’s loop

This is another of those knots intended to be tied in the bight. It has been used to secure the

middle one of a trio of climbers, but acquired its name from its earlier use in manhandling field
guns, when a series of shoulder loops were created in draglines for men to haul upon. In this
way it could also ease the load upon horses struggling to pull coaches and carriages uphill, hence

its other name of “manharness” knot or hitch. Another application, by horse riders in the US,
has been as a static picket-line knot to tether their steeds at overnight campsites.

Make a loop with the working end on top (1). Then pass it beneath the loop just formed (2). Pull
the right-hand section of line under, then over, and up through the original loop (3), to replace it
and create the final loop (4). Remove any slack by pulling first on both standing parts of the line,
and then by tugging on the loop itself (5).
