by John Marshall, Royal Naval Biography — Butterfield… (1823)
“ There is no service more arduous and unprofitable than that of convoying merchantmen. Most of those placed under Captain Butterfield’s care were heavy sailers, deeply laden, weakly manned, badly found, and sometimes leaky; demanding the greatest skill, perseverance, and patience, to keep them together. Privateers were continually on the watch, waiting only for a gale of wind, or a fog, to separate the unskilful from the rest; yet, with all these difficulties to contend with, Captain Butterfield had the good fortune never to lose a single vessel confided to his charge. ”
