A dispatch from Cienfuegos, Cuba, dated Feb. 1, says: Col. Gardener received orders from Gen. Bates this afternoon to take his regiment to Amaro, near Sugua la Grande, three miles east of Rodrigo, a railroad station. The first battalion, under command of Maj. Hunt and Col. Gardener, will go by rail to Rodrigo tomorrow. The officers and men will take shelter tents along until all the regimental baggage arrives. They will unload and guard the baggage and stores until the regiment arrives. - The second and third battalions will remain in Cienfuegos and guard the regimental property until it is loaded on the cars. During their sojourn in Cienfuegos, the second and third battalions will sleep in pup tents. Amaro is about 80 miles from Cienfuegos, and is about 20 miles from the northern coast of Cuba. It is a summer resort for wealthy Cubans. Capts. Fenton and Smoke were aboard the Chester this afternoon. The Alava, loaded with Spanish troops returning to Spain, passed our steamer this evening.
