on august 30 the polish navy, realizing what was about to happen, sent 3 destroyers (błyskawica, grom, and burza) to the uk. the group was spotted the 30th in the southern ostsee by the u 31 and again, in the skagerrak, by u 19 on the 31st.  since the war hadn’t started they were unmolested. with the destroyers gone some of the ships deployed to the ostsee were recalled and some sent to the nordsee. the fleet was in the process of shifting its deployment when the war broke out.  (later, the submarines orzeł and wilk also made it to the uk, while the sęp, ryś and żbik, sought internment in sweden.)
