The following constitutes the Schedule 13D filed by the undersigned (the "Schedule 13D").

Item 1.

Security and Issuer.

This statement relates to the Common Stock, par value $0.01 per share (the "Shares"), of Peabody Energy Corporation, a Delaware corporation (the "Issuer"). The address of the principal executive offices of the Issuer is 701 Market Street, St. Louis, Missouri 63101.

Item 2.

Identity and Background.

As the two controlling shareholders of the Master Fund, each of the US Feeder and the Cayman Feeder may be deemed to beneficially own the Shares owned by the Master Fund.  Mangrove Partners is the investment manager of each of the Master Fund, the US Feeder and the Cayman Feeder. Mangrove Capital is the general partner of the US Feeder. Mr. August is the director of each of Mangrove Partners and Mangrove Capital.  By virtue of these relationships, each of Mangrove Partners, Mangrove Capital and Mr. August may be deemed to beneficially own the Shares owned by the Master Fund.

Item 3.

Source and Amount of Funds or Other Consideration.

A total of approximately $7,121,051 was paid to acquire the securities reported as beneficially owned by the Master Fund. The funds used to purchase these securities were obtained from the general working capital of the Master Fund, including margin account borrowings made in the ordinary course of business, although the Reporting Persons cannot determine whether any funds allocated to purchase such securities were obtained from any margin account borrowings.

Item 4.

Purpose of Transaction.

The Reporting Persons purchased the securities of the Issuer reported herein based on their belief that such securities are undervalued and represent an attractive investment opportunity. Depending upon overall market conditions, other investment opportunities available to the Reporting Persons, and the availability of securities of the Issuer at prices that would make the purchase or sale of such securities desirable, the Reporting Persons may endeavor (i) to increase or decrease their respective positions in the Issuer through, among other things, the purchase or sale of securities of the Issuer on the open market or in private transactions or otherwise on such terms and at such times as the Reporting Persons may deem advisable and/or (ii) to enter into transactions that increase or hedge their economic exposure to the Shares without affecting their beneficial ownership of Shares.

The Reporting Persons are in the process of retaining legal and financial advisors to assist them in seeking the formation of an official equity committee and to preserve and realize on the substantial value of the Shares. In addition, the Reporting Persons intend to contact and speak with other holders of the Shares for the foregoing purposes.

No Reporting Person has any present plan or proposal which would relate to or result in any of the matters set forth in subparagraphs (a) - (j) of Item 4 of Schedule 13D except as set forth herein or such as would occur upon or in connection with completion of, or following, any of the actions discussed herein. The Reporting Persons may take positions regarding or make proposals with respect to, or with respect to potential changes in, the Issuer's: operations, management, certificate of incorporation and bylaws, composition of the Board, ownership, capital or corporate structure, dividend policy, potential acquisitions or sales, businesses or assets, strategy and/or plans of the Issuer as a means of enhancing stockholder value. The Reporting Persons may change their intention with respect to any and all matters referred to in Item 4. The Reporting Persons intend to review their investment in the Issuer on an ongoing basis and may from time to time in the future express their views to and/or meet with management, the Board, other stockholders or third parties, including, potential acquirers, service providers and financing sources, and/or may formulate plans or proposals regarding the Issuer, its assets or its securities. Such possible plans or proposals may include one or more plans or proposals that relate to or would result in one or more of the changes referred to herein, or any of the matters set forth in subparagraphs (a) - (j) of Item 4 of Schedule 13D.

Item 5.

Interest in Securities of the Issuer.

As of the date hereof, the Master Fund beneficially owned 971,058 Shares, including 75,558 Shares issuable upon conversion of the 4.75% Convertible Junior Subordinated Debentures due 2066 of the Issuer held by the Reporting Persons, constituting approximately 5.2% of the Shares outstanding. By virtue of their respective relationships with the Master Fund discussed in further detail in Item 2, each of the US Feeder, the Cayman Feeder, Mangrove Partners, Mangrove Capital and Mr. August may be deemed to beneficially own the Shares owned directly by the Master Fund.

Each Reporting Person, as a member of a "group" with the other Reporting Persons for the purposes of Section 13(d)(3) of the Securities Exchange Act of 1934, as amended, may be deemed the beneficial owner of the Shares directly owned by the other Reporting Persons. Each Reporting Person disclaims beneficial ownership of such Shares except to the extent of his or its pecuniary interest therein.

Item 6.

Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

On October 24, 2016, the Reporting Persons entered into a Joint Filing Agreement (the "Joint Filing Agreement"), in which the Reporting Persons agreed to the joint filing on behalf of each of them of statements on Schedule 13D with respect to the securities of the Issuer to the extent required by applicable law. The Joint Filing Agreement is attached as Exhibit 99.1 hereto and is incorporated herein by reference.

The Reporting Persons currently own 4.75% Convertible Junior Subordinated Debentures due 2066 of the Issuer in the principal amount of $64,779,000.

Other than as described herein, there are no contracts, arrangements, understandings or relationships among the Reporting Persons, or between the Reporting Persons and any other person, with respect to the securities of the Issuer.
