Hesse-Engelburg Warships in Tradgarland?

A small Hesse-Engelburg squadron comprising three frigates and two smaller vessels has reportedly been noted entering Tradgarland through the river which joins the two countries, sailing north at best speed. Several observers have indicated that one of the smaller vessels is a dispatch cruiser bearing the state flag and the personal arms of Colonel Freidrick von Heiner, previously known to have been engaged in delivery of diplomatic messages to such nations as Vulgaria.

With the non-agression pact between Hesse-Engelburg and Tradgarland on the one hand, and the recent declaration of a free state by the former Tradgarland forces on Shetland, speculation is rampant as to the squadron's intent, but by all present appearances it is making for the sea.
