ENThis article presents six groups of relations about the capture of Smolensk in the year 1611 by Sigismund III Waza's army. All texts contain a description of attacks and stages of occupancy of the fortress and city. The texts belong to a few literary genres. We distinguish: letters, diaries, news, triumphs, epinicions, epic-verse relation, biographical epos and chronicles. Attributing the text to the chosen categories decides the situation of communication: times, occasion, sender's purpose, places where a message was prepared, and the interest of the recipients. In the first group we have rudimental relations prepared at the places in Smolensk; in the second group fits the relations published at Vilnius, near the field of battle; in the third group are a texts which were printed in the central part of Republic: in Kraków and Poznań; in fourth group are descriptions of triumphs organized in the principal cities of regions, and a P. Skarga's sermon; the fifth group contains relations which jointly presents a relation and description of triumph; finally in the sixth group we have a chronicle, epos and diary. They are large forms in which a relation from Smoleńsk is only a small part of communication. The authors occasional texts are writing to the their contemporaries, in turn historians and writers of epics address to descendants, not only informing them, but also interpreting events for them. Also we observe exchanges in the choice of literary forms. From these occasional forms, they evolve to the relations in which presentation of events constitute a part of the historical process.
