Prince William is making a surprise two-day visit to Poland, starting with a military base along the border with Ukraine Wednesday to thank troops for their commitment to helping the country defend itself against Russia. "I just wanted to come here in person to say thank you for all that you’re doing, keeping everyone safe out here and keeping an eye on what’s going on,'' the Prince of Wales told British and Polish troops gathered in Rzeszow, a city in the southwest of the country that has become a hub for shipments of military and humanitarian aid bound for Ukraine. The city is around 40 miles from the Ukrainian border and is also a transit hub for refugees. "You’re doing a really important job out here and defending our freedoms is really important, and everyone back home thoroughly supports you," he added.
