A passage from De Jonge about the fleet sent to aid Venice in 1618

This is based on my first cut at a translation of a passage from De Jonge's book , Geschiedenis van het Nederlandsche Zeewezen, Vol.I, from 1858:

It deserves to be noted that it assisted the Dutch common good in these years of truce to aid the Republic of Venice not only with soldiers but also with warships. Twelve ships under the command of Admiral Melchior van den Kerckhove left in the year 1618, and others followed. The Dutch assistance fleet behaved courageously and proved to be valuable to the Venetian service. In the meantime, it was less from the services performed for pay that the aid fleet was sent. It was more to prove to what degree the power of the United Netherlands had grown. It was now able to provide other nations with assistance and the renown of its navy had already been established in these days that others called upon its help.
